Mixed bag of terrian. Fire roads, singletrack, doubletrack and some dirt roads. Extremely rocky with high technical score. Trails stretch out and can be ridden all the way to Buck Hill in Pascoag. Don't park at the Beach it will cost three bucks. Main trail parking lot. Check out the coffee house loop?
The forest is located off of Rte 16 in Douglas Ma. Easy to get to from 495 anywere.
