Singletrack heaven. Good luck not getting lost. Lots of good peeps ride and do trail work here. Pitch in, join NEMBA, Be respectful and ride hard. Many miles to ride.
Take rte 28 west from Hyannis, veer right onto rte 151 after Rotary. Take 151 almost to the junction with rte 28 and just before the ramp on the right is a pull off parking area with a mound of sand. Park here.
