Although Gettysburg's crime rate is relatively low, theft does occasionally occur, so lock your car when it's not in use and keep an eye on your belongings at all times. When visiting Gettysburg National Military Park, rangers recommend dressing accordingly for the season (including wearing sunscreen on sunny days), keeping a safe distance from wild animals and packing plenty of water for hikes and bike rides.

Those who venture off of walking trails should also be mindful of ticks, which are often spotted in areas with tall grass and brush during the warmer months. These tiny critters can transmit Lyme disease if they're attached to you for at least 24 hours. To protect yourself from ticks, apply insect repellent with DEET regularly and wear pants and a long-sleeved shirt. Don't forget to check your clothes and skin frequently and to shower shortly after being outside. If you are bitten by a tick, immediately remove it with tweezers. To learn more about how to avoid ticks at Gettysburg National Military Park, check out the park's Tick Safety page.
