The Friends of Raystown Lake received a lease from the U.S. Army Corps of Engineers to build and operate the 36 mile long Allegrippis Trail System.  These trails have received formal and informal acclaim for their design, sustainability, economic and other benefits.  The trails offer some of the best mountain biking opportunities on the east coast and are a mecca for enthusiasts from across the country- thanks to The Friends of Raystown Lake and to the dedicated members of the Raystown Lake Mountain Bike Association (RMBA) who maintain the trails year-round!
