U.S. News Insider Tip: In between surf sessions, refuel with a Banán bowl at its Waikiki Shack off Kalakaua Avenue. Its soft serve "ice cream" is made from locally grown bananas with toppings like macadamia nut honey butter, fresh papaya and dark chocolate. – Sharael Kolberg, Contributor, Travel

Nineteenth-century Hawaiian royalty used to come to the Honolulu neighborhood of Waikiki to relax and surf, just as scores of tourists do today. That's because this area's famous beach (which is a string of several beaches dotting the island's southwest coastline) is the go-to spot for its soft, honey-colored sand and the high waves that lap the shores during the winter months. But you don't have to be a surfer to appreciate Waikiki Beach; just lie back on a beach towel, relax and gaze at the majestic, Le'ahi, or Diamond Head State Monument, in the distance.

U.S. News Insider Tip: Plan for a full day at Pearl Harbor. Even if you don't spend the whole day here, it's a lot to take in and you won't want to rush to another activity or dinner reservation. – Amanda Norcross, Content & SEO Strategist

Located less than 10 miles northwest of downtown Honolulu in the Central O'ahu region of the island, the Pearl Harbor National Memorial is home to the USS Arizona Memorial, which is the final resting place of more than 900 sailors and marines killed during the Pearl Harbor attack in 1941. The sunken battleship is still visible from the memorial floating above it. Many visitors say this is a "must-do" attraction, and recommend reserving your free ticket well in advance since availability is so limited due to high demand.

The Hawaiian name for Diamond Head is Le'ahi. It is a tuff cone (consolidated volcanic ash) crater that was created 300,000 years ago during a single volcanic eruption that spewed ash into the air. That ash settled over thousands of years, and today, Diamond Head State Monument's ridgeline is one of the most recognizable features of O'ahu's skyline, not to mention home to one of the island's most scenic hiking trails.

Though the 0.8-mile hike from the trailhead to the summit is steep and strenuous, gaining 560 feet, travelers say you'll be rewarded with a surreal view of Waikiki Beach and the Pacific Ocean once you reach the top. But keep in mind that this natural wonder is one of Honolulu's most popular attractions, so consider arriving early to beat the heat and the crowds. Also, remember to bring plenty of water, since no water fountains are available on the trail. For a different (less strenuous) perspective, consider opting for a helicopter tour. Many of the island's air tours fly directly over the crater.

Located about 10 miles east of Waikiki, the family-friendly Hanauma Bay Nature Preserve is one of the best places to snorkel with exotic fish and marine life. It is also a state park and is situated within a volcanic cone, which naturally protects it from the elements, such as wind and waves.

To reach Hanauma Bay, you can take an Uber or drive yourself (it costs $3 to park); tour buses are not allowed to enter the park. Be aware that the parking lot fills up quickly. Entrance to the park costs $25. Children 12 and younger, active military and kama'aina (Hawaiian residents) can enter for free with state ID. Tickets must be reserved online and paid for in advance through the Honolulu Parks & Recreation website. Since there is a restriction on how many visitors are allowed per day due to conservation efforts, recent travelers complained that it is difficult to get a reservation, and suggest booking well in advance. Once there, reviewers raved about the number and variety of reef fish.

Launched in 1944, the USS Missouri (or "Mighty Mo") is best known for hosting a meeting between Allied and Axis representatives that led to Japan's surrender and the end of World War II. After the war, the ship served in the Korean War and the Gulf War before docking in Pearl Harbor and opening as a memorial. It holds the distinction of being the world's last active service battleship.

According to recent visitors, the Battleship Missouri Memorial's war artifacts and exhibits complement the displays at the Pearl Harbor National Memorial. Many past travelers also praised the attraction's knowledgeable tour guides. However, some wished bags/purses could be taken on board and suggested leaving personal items behind to avoid paying a $7 per bag storage fee.

Less than 6 miles northeast of the Koko Crater Trail lies the 2-mile round-trip Makapu'u Point Lighthouse Trail. Easier to trek than the one at Koko Crater, this free trail overlooks the Pacific Ocean and is a prime spot for spotting seabirds and whales between November and May. The path also leads to the red-roofed Makapu'u Lighthouse, which was built in 1909.

Visitors love that the Makapu'u Point Lighthouse Trail is paved and features ample benches, making it easy for travelers of all ages to explore. Many also rave about the trail's "amazing" views, adding that bringing a camera is a must. But remember, this path is mostly exposed to the sun and wind, so dress appropriately, wear sunscreen and pack plenty of water. Hawaii's Department of Land and Natural Resources recommends allotting at least two hours to complete this hike.

U.S. News Insider Tip: Arrive to the trailhead by 5 a.m. to beat the heat and allow time for breaks so you can reach the summit by sunrise. You'll also want to bring a headlamp as you'll be traversing uneven steps in the dark. – Amanda Norcross, Content & SEO Strategist

The 1.6-mile round-trip hike to the top of Koko Head Crater features more than 1,000 steps made from abandoned railroad ties. At the trail's summit, visitors will find panoramic vistas of the Hanauma Bay Nature Preserve and Diamond Head State Monument.

Travel about 15 miles northeast of downtown Honolulu to the Windward Coast and you'll discover two of the island's most popular beaches – Kailua Beach Park and Lanikai (or Ka'ohao) Beach. Of the two, Lanikai is more tranquil and offers relatively calm waters. This family-friendly beach is also within view of the postcard-perfect Mokulua Islands (or Na Mokulua), which is a popular spot to kayak to.

Beachgoers praise Lanikai Beach's beautiful water, adding that its location in a mostly residential part of Kailua makes it less crowded and more relaxing than Waikiki Beach. But the beach's Kailua address is also its biggest drawback: Several visitors warn that parking in the area is limited. Even with the limited parking, reviewers praise the beach's soft sand and brilliant water.

In ancient Hawaiian times, the Puowaina (Punchbowl) Crater was used for human sacrifices to the Polynesian gods. Now, it's the final resting place for men and women who served in the U.S. military. The National Memorial Cemetery of the Pacific stretches across much of the crater and contains several moving tributes, including the Honolulu Memorial, which is dedicated to armed forces who fought in the Pacific during World War II, the Korean War and the Vietnam War. Notable veterans buried here include Ernie Pyle (the famous World War II correspondent) and Stanley Armour Dunham (the maternal grandfather of former President Barack Obama).

Previous visitors raved about the cemetery's beautiful and peaceful setting, adding that its memorial markers are very informative. Many compared it to Arlington National Cemetery and the Vietnam Veterans Memorial. Others highlighted the spectacular views as reasons to plan a visit.

U.S News Insider Tip: This should be a "must do" when visiting Oahu. Stop here early in your trip for a better appreciation of Hawaiian history and Polynesian culture. – Sharael Kolberg, Contributor, Travel

If you want to find out more about Hawaiian history and culture, then head to the Bishop Museum. It was founded in 1889, in honor of the wife of museum founder Charles Reed Bishop, Princess Bernice Pauahi Bishop – the last descendant of the Kamehameha royal family. The property houses more than 25 million historical, cultural and natural artifacts about Hawaii and the Pacific. Exhibits include the three-story Hawaiian Hall (where visitors can learn about Hawaiian gods, key events in Hawaiian history and more) and a planetarium. The planetarium features "Wayfinders," a full-dome projection program that puts viewers on the deck of the voyaging canoe, Hokule'a, as it travels from Tahiti to Hawaii using traditional Polynesian navigation techniques.

U.S. News Insider Tip: Manoa Falls is located in Manoa Valley, home to the University of Hawai'i at Manoa. The university's football team, the Hawaii Rainbow Warriors, gets its name from the rainbows often spotted in the valley. – Sharael Kolberg, Contributor, Travel

This approximately 150-foot-tall waterfall, which sits 5 miles northeast of downtown Honolulu, is easily accessible. All you need is proper footwear, insect repellant, drinking water and the stamina to hike about 1½ miles on a well-worn path. The rainforest scenery is otherworldly, with enormous prehistoric ferns and the snaking roots of banyan trees. It's no wonder why Steven Spielberg filmed scenes from "Jurassic Park" here. You probably won't see any dinosaurs but be prepared: The path to the falls can be quite slippery with mud, so wear sturdy hiking shoes that you don't mind getting dirty.

Completed in 1882, this 10-room historic house, museum and National Historic Landmark details the reigns of King Kalakaua and his sister, Queen Lili'uokalani, Hawaii's final monarchs. It is the only official state royal residence found in the U.S. Among its opulent features are a grand Hawaiian koa wood staircase, portraits of Hawaiian kings and queens, royal thrones and decorative objects from around the world.

Recent travelers appreciated the unique glimpse into Hawaii's culture that this attraction offers. However, you'll need to keep a few rules in mind when touring the property. Kids younger than 5 must be strapped into a child carrier or palace-provided stroller at all times. Wearing cloth booties to protect the palace's floors is also required.

U.S. News Insider Tip: Kailua Beach tends to be windy. For a nearby alternative, head over to picturesque Lanikai Beach, which is accessible off Mokulua Drive at Mokumanu Drive. – Sharael Kolberg, Contributor, Travel

If you like to kite surf or windsurf (or watch others participate in the sports), head to Kailua on the Windward Coast and find a perch at Kailua Beach. This 2 1/2-mile stretch of white, shaded sand and warm, turquoise-hued water appeals to both families and adrenaline junkies thanks to its gentle waves and ample facilities, including picnic tables, restrooms and free parking.

This is a must-see attraction to learn about the rich heritage of the Pacific Islands, including Hawaii, Fiji, Samoa and Tahiti. The 42-acre property features "villages" representing six different islands, with traditional music, art, food, dance, games, architecture and plenty of hands-on activities for the kids. Admission starts at $79.95 for adults and $63.96 for children ages 4 to 11 – these prices include a self-guided tour of the villages and a digital photo.

After visiting the attractions, stay for an authentic lu'au dinner and show. Lu'au packages cost $189.95 for adults and $151.96 for children ages 4 to 11. It also includes a guided tour through the villages, among other perks.

The Hawaiian Islands boast more than 1,200 miles of coral reef, so it's hardly surprising that two of O'ahu's most popular activities are snorkeling and scuba diving. Dive into the island's surrounding turquoise water and you'll likely find an array of colorful fish (think: bright yellow tang, rainbow runners and Hawaii's state fish, humuhumunukunukuapua'a, or rectangular triggerfish), plus bigger marine creatures like dolphins and sea turtles.

Past travelers loved snorkeling for free at public beaches like Sans Souci Beach Park on the south end of Waikiki and Shark's Cove on the North Shore (don't let the name scare you – it's a great place for spotting sea turtles), citing the ample marine life and clear water as reasons to return. If you don't have your own snorkel equipment, your hotel or resort may provide gear. If not, you can rent some; fees vary by shop and rental period. Popular locations include Snorkel Bob's, Aqua Zone Scuba Diving & Snorkeling and Hawaii Beach Time. If you'd prefer a guided snorkeling tour, try traveler-approved Hanauma Bay Tours, which provides round-trip transportation between Waikiki and Hanauma Bay Nature Preserve, as well as snorkel equipment.

U.S. News Insider Tip: The hike to Waimea Falls is about 3 ½ miles of flat, paved road with breathtaking scenery. Pack a picnic, take a swim and enjoy the surroundings. Also leave time to visit Waimea Bay Beach across the highway. – Sharael Kolberg, Contributor, Travel

Not only is Waimea Valley a beautiful place to explore, with lush landscaping, 52 themed botanical gardens, native ecosystems, native birds and a waterfall, but it is also, more importantly, a sacred Hawaiian historical and cultural site. Waimea Valley is rooted in Hawaiian history and continues to be a steward for Hawaiian spirituality and traditions. On the property, you'll find six significant cultural sites, including traditional Hawaiian shrines, houses and agricultural terraces. Resident artisans share their knowledge of Hawaiian history, artistry and craftsmanship.

On the south end of Waikiki, you'll find Kap'Iolani Regional Park, which includes the Honolulu Zoo and Waikiki Shell (a venue for outdoor concerts). It is one of the largest public parks and the second-oldest park on O'ahu. Facilities include tennis courts, soccer fields, an archery range and a 3-mile jogging course. It is a popular destination for locals and visitors alike. Recent visitors say it is a wonderful place to take a stroll and recommend pairing it with a stop at the Honolulu Zoo if you're traveling with kids. Others recommend the park for its views of Diamond Head and its quiet atmosphere.

Metered and free parking are available along the streets bordering the park. Across the street from the park is Kap'Iolani Park Beach and Kaimana Beach, as well as the Waikiki Aquarium and the traveler-approved Barefoot Beach Café. The park, which is free to access, is open daily from 5 a.m. to midnight. For more information, visit the Honolulu Parks & Recreation website.

If horseback riding, e-bike tours, zip lining or a jungle Jeep excursion are on your vacation to-do list, a visit to Kualoa Ranch is a must. Not only is the lush landscape stunningly beautiful, but it is also an adventure-lovers dream. Movie buffs will also dig it since it was the filming location for the "Jurassic Park" franchise, among other films. The 4,000-acre property on the Windward Coast is a private nature reserve and working cattle ranch, and is located about 20 miles from central Honolulu and 30 miles from the North Shore. The ranch is located just across the highway from the ocean (with picturesque views of Mokoli'i), which means water sports activities like catamaran tours and kayak and paddleboard rentals are also an option. All tours are guided and range in activity level. Tour lengths range from 90 minutes to three hours.

Breathtaking scenery and movie memories are what some recent visitors liked most. Many reviewers recommended the e-bike and all-terrain vehicle tours.

It's no secret: O'ahu is home to some of the world's best surfing spots. Every winter (when surfing conditions are at their best), professional surfers from across the globe flock to O'ahu's North Shore to shred some gnarly waves in the Vans Triple Crown of Surfing. Basically, the Super Bowl of surfing, the Triple Crown is held during the winter months when massive swells roll in from the stormy northern Pacific Ocean. But you don't have to be a pro to hang 10 on O'ahu. There are plenty of surf schools that will take you from a grom (local slang for a surfing newbie) to a "Big Kahuna" (or master surfer) in the course of a day. Best of all: No one will laugh if you wipe out (and you will).

Previous first-timers loved surfing Waikiki Beach's calm waves, while the most experienced surfers tackled the large swells found at Waimea Bay on the North Shore. If you plan on taking surfing lessons, consider traveler-approved surf schools like Ohana Surf Project, Polu Lani Surf Lessons & Adventures and Hans Hedemann Surf School. Most will teach anyone who's willing to learn, no matter their skill level.

Managed by the University of Hawai'i at Manoa, the Lyon Arboretum is a 200-acre arboretum and botanical garden located at the upper end of Manoa Valley about 5 miles north of Waikiki. In addition to more than 6,000 plants, the arboretum features more than 7 miles of hiking trails.

Past visitors recommend wearing shoes with sturdy soles as many of the paths are very rocky, but many say they enjoyed the beautiful gardens. Despite its close proximity to downtown Honolulu, reviewers said the arboretum felt world's away.

The Ho’omaluhia Botanical Garden is spread across 400 verdant acres and features plants from major tropical regions around the world grouped geographically. Regions represented include Malaysia, Polynesia and Africa, among others. Opened in 1982, the garden was designed and built by the U.S. Army Corps of Engineers to provide flood protection for Kane'ohe.

The scenic view of the cliffs, lush gardens and a lake full of fish were just some of the highlights enjoyed by recent visitors. Reviewers recommend wearing sturdy walking shoes to make use of the many trails. Others said a stop here is a great way to spend a day away from the beach and recommend bringing supplies for a picnic.

In 2011, the Honolulu Academy of Arts joined forces with The Contemporary Museum to create the Honolulu Museum of Art. This museum features an art collection that spans across seas, styles and centuries. Along with pieces by Europe's great painters (Picasso, Gauguin and van Gogh, to name a few), the Honolulu Museum of Art showcases one of the world's best Asian art collections. The museum is also home to the Doris Duke Theatre, which screens independent, documentary and international films.

Many visitors praise the property's Asian art, but for a truly unique experience, several recommend checking out the Arts of Hawai'i collection, where you can view Georgia O'Keeffe's Maui landscapes, along with indigenous feather capes. Several reviewers noted that admission to the museum is included with your purchase of a tour of Shangri La, the former home of philanthropist and heiress Doris Duke. 

Like the Battleship Missouri Memorial, the USS Bowfin Submarine Museum & Park sits in Pearl Harbor. This historic vessel, which went on nine patrols during World War II, is one of only 15 U.S. World War II-era submarines that still exist. It now serves as a walk-through exhibit alongside a museum with various war artifacts, including battle flags and a submarine bell. Additional items, such as a cruise missile, a torpedo and a submarine rescue chamber, are on display in the surrounding park.

Some former travelers lamented the limited elbow room offered inside, but overall, many appreciated getting a firsthand look at the tight living quarters sailors had to endure while stationed on this submarine. Others enjoyed the self-guided audio tours covered by museum and submarine admissions.

For a scenic and serene alternative to the beach, head to the Valley of the Temples Memorial Park, where you'll find the Byodo-In Temple, a Hawaii State Landmark that was established on June 7, 1968, to commemorate the 100-year anniversary of the first Japanese immigrants to Hawaii. The temple is a non-practicing Buddhist temple that welcomes visitors of all faiths to worship, meditate or simply admire its beauty. The lush grounds are located at the foot of the Ko'olau Mountains on the Windward Coast, about 15 miles north of downtown Honolulu. Along with the temple, the stunning grounds include a large reflecting pond, meditation niches, small waterfalls, the golden Amida buddha, bon-sho sacred bell and koi ponds. If you visit, you'll want to keep a few things in mind: Be respectful and quiet while in the Valley of the Temples – it is a solemn, religious area. Remember to remove your shoes before entering the Byodo-In Temple.

Ringing the bell is a must-do, according to recent visitors. Many enjoyed the peaceful atmosphere and the beautiful backdrop for snapping pictures. Reviewers recommend arriving early to avoid the tour bus crowds that descend on the grounds by midday.

Located at the north end of Waikiki, Fort DeRussy Beach Park is 71-acre beachfront military reservation that is almost entirely open to the public. The park is bordered by a section of Waikiki Beach and features a playground, workout stations, picnic tables, barbecue grills, pickleball courts, racquetball courts, volleyball courts and the U.S. Army Museum of Hawaii.

Past visitors said this is a great place to go for a relaxing stroll thanks to its beautiful trees and well-groomed lawns. Others said the park and its section of Waikiki beach are ideal for children as the waters are calm and shallow.

The philanthropist and American tobacco heiress Doris Duke spent her winters living in this opulent oceanfront home near Diamond Head State Monument. Today, it's a museum of Islamic art, culture and design. Duke began building it in 1937 and then spent nearly 60 years filling its walls and rooms with art and furniture from Egypt, India, Morocco, Spain, Syria and Turkey. By the end of her life, she had amassed approximately 4,500 objects, which are now available for you to see on a tour of her home.

Art lovers should definitely make plans to stop by Shangri La, but you should also consider visiting the home if you're just a teensy bit curious about the enigmatic heiress. Many recent travelers were more than impressed with this museum, describing its collection as "unbelievable" and well worth a visit. Several also pointed out that the property itself – which is often compared to grand estates like Topkapi Palace in Istanbul and the Taj Mahal in Agra, India – can't be missed.

If you're looking for a kid-friendly outing, plan a visit to the 42-acre Honolulu Zoo (which sits across the street from the southern end of Waikiki). It is home to a variety of amphibians, birds, mammals and reptiles, including black rhinoceros, Asian elephants, cheetahs, giraffes, lions, primates, zebras and more. The zoo is divided into the following sections: African Savanna, Reptiles, Birds and Primates. There is also a Keiki (Kids) Zoo, a picnic lawn, a playground, several gardens, a snack bar and restrooms.

Families who visited said it was nice to have an alternative to the beach and shopping, and were impressed with the wide variety of animals. However, a few noted that the zoo is small.

For all things pineapple, visit the Dole Plantation. About 10 miles inland from the North Shore and 20 miles northwest of Honolulu, the plantation offers activities and tours that are fun for the entire family. Hop aboard the narrated Pineapple Express Train, stroll through the Plantation Garden, get lost in the Pineapple Maze Garden, learn how to cut a pineapple, watch a chocolate-making demonstration or feed the fish in the pond. The on-site Plantation Grille serves island favorites, including teriyaki chicken plates, kalua pork plates and loco moco (white rice topped with a hamburger, a fried egg and brown gravy), as well as the must-try Dole soft serve.

Many visitors complained that the Dole Plantation is an overcrowded tourist trap, but most agreed that the Dole Whip was the highlight.

There are many places in Honolulu to put down some cash and pick up some souvenirs, but none are as extensive as Ala Moana Center. Located northwest of Waikiki Beach and roughly 2 miles southeast of the city center, this behemoth open-air shopping center boasts a collection of high-end stores like Chanel and Gucci, department store staples like Nordstrom and Neiman Marcus, and tourist-kitsch shops like Jams World. Its 350-plus shops and restaurants can take as little as an hour or as much as a whole day to explore.

Although some visitors warn that items sold at Ala Moana Center can be quite pricey, many enjoy shopping here, especially on rainy days. Others rave about the on-site dining options, especially the poke bowls at Foodland Farms and the Japanese snacks and prepared foods at Nijiya Market. Reviewers also say the free, 20-minute evening hula show cannot be missed.

U.S. News Insider Tip: Hold on to your hat if you make a stop here – it's quite windy on this side of the island. – Ann Henson, Assistant Managing Editor

For a glimpse of a natural wonder, plan a visit to the Halona Blowhole, considered O'ahu's own Old Faithful. Situated less than 15 miles east of Waikiki, the blowhole was formed by molten lava tubes from volcanic eruptions that occurred thousands of years ago. Depending on the size of the ocean waves, water can shoot up to 30 feet in the air. Aside from observing the natural phenomenon, you may also be able to see the islands of Moloka'i and Lanai on a clear day.
