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!  Hunting seasons are underway and all riders are urged to wear orange while on the trails.
