This is a hard review to give. The line is very long and I’m not sure it is any better than the boat trip that comes up to the falls. The two tunnels that you go look at when you are down there are somewhat pointless, all you see is water? I would probably just do the boat tour.

Seeing the falls from this perspective was amazing. The people working the attraction were friendly and informative. We went over Memorial Day weekend, and the line was extremely long. We pre-purchased our tickets for a 2pm times slot. We got on the line at 1:40 pm and entered the attraction at 2:50 pm. I hope that the lengthy wait time is not the norm, and that the crowd and long line was because it was a holiday weekend in the U.S. Once in the attraction, there were more lines in order to see the lookout points from inside, prior to the end where you are out on a deck. You are permitted to skip those lookouts and go straight to the deck area. We looked at both, but if the lines are long, I recommend checking one out and skipping the other, as I think they are similar. I don't mean to dissuade anyone from doing this experience, because it was interesting, but be careful about timing reservations for dinner, or another activity following this one, especially on weekends and other busy times.

They provide a poncho, so don't worry. I would recommend skipping the long lines in the tunnels and go straight to the observatory. The tunnels are ... listen! You take a picture with water few feet behind you. Really? Don't waste your time. The jewel is the observation because you get the full view of the falls and its where the real fun is!

Bit short, not a ton of information but still neat! Expect to wait in a dark tank tunnel with shrieking teens who have discovered it echos and just acknowledge you’ve entered the 1st circle of hell for 30 minutes. But once you get to the falls, it’s amazing. You can hear and feel the power. Even with the noise I’d go again.

It was ok. We waited in a long line to get to what we thought was the main spot. We ended up in the tunnel, which at the end only allowed you to take a pic from inside the tunnel. Not at all worth the wait. The best place is the observation deck. Don't bother with the tunnel.

This was a little disappointing. No tour guide. You literally take an elevator down, walk through a tunnel where one view is out like a window to “see behind the falls.” Then the other view is to take a picture of the waterfalls which you can do from the side of the road. If you are on the fence of doing this tour or not I would say skip it and spend the money elsewhere.

It was great to get that close to the falls but there were multiple tunnels and no real direction by anyone. Found lines that we had no idea where they went. Found out we could see the same thing standing in one line instead of waisting time waiting in all of them. For issues with time, go stand in one line to see the water flowing down then goto the area where it opens up. That’s where the fun really is. That’s where you get wet and enjoy what you see.

So it was a thing to do but if you have the ability to cross the border and go to cave of the winds it is much more fun and wet. Journey behind the falls is basically one long tunnel with 2 windows. You may have to wait in line to look out the windows. The best part is the platform you can walk out onto and stand in the spray from the horseshoe falls. You will get wet if you go to the right of the platform but not so much if you stay to the left. All in I took about 20 minutes. Mostly waiting for the windows or the elevator. Going to the bottom of the falls is a must but again if you have the choice, choose the cave of the winds. If you can’t cross the border do journey behind it’s still cool to be at the bottom.

Nice visit to the bottom of the falls and a look behind the falls. Only takes about 30 minutes total. But the wait in line for the elevator down and back up took much longer. It was pretty crowded.

Lines for entry to the experience were long, winding, and tedious. For what you get to experience, it wasn't worth our time. You get a good view from the "deck" but the trek down the "tunnels" was a waste of time. You see nothing but mist and you are restricted by a barrier 20ft a way from the water. We were underwhelmed and wished we hadn't gone through the motions.
