The riding in the Bourne/Falmouth area is usually referred to as riding at Otis Air Force Base. The base has been officially closed to anyone except official personal since the events of September 11th.

Most people don't realize that there is riding on Town Of Falmouth and Crane Conservation Land, which is not part of the base. Unfortunately, there is really no physical delineation between these areas. People are still riding Otis without being bothered by military police. If you happen to be crossing a paved road and encounter a base official, they will ask you to leave, or perhaps escort you out. They are not out there patrolling, looking for mountain bikers in the woods.

These best way to access the riding is from route 151. There are a lot of trails in this area which do not go onto base property. Parking is along Route 151 near the dirt mound on your left after you exit from MaAurther Blvd. (Rt.28). There is also parking a little further down the road through the yellow gate on Cloverfield Lane. From here, you bike to the end of the big field, cross the railroad tracks and enter the trails area.
