Get in the Water at Harpers Ferry
Make time for some tubing or rafting at Harpers Ferry! There is plenty of history to check out, but you can get in the water too... There are a couple of places near the park that provide equipment, tours, shuttles, etc. For tubing experiences, you park your car in a designated place and they take you up river in a shuttle bus... you get in the water and float back to your start point. Great way to relax, cool off and have some fun with friends (once we can get back outside!)
For those who are looking for a little more adventure, you can do a rafting tour down through some of the rapids on the Potomac branch, a little upstream from the Park proper. Great fun !
