Lots of single track loops off of a main doubletrack route. The terrain gets more challenging the farther from the parking area you travel. We rode for 2 1/2 hours and had to stop to find our way back out. It is easy to get sucked in and keep rallying and easy to forget how many lefts and rights you've made. Print out a copy of the map from the NEMBA website and all will be fine...(throw some money at them too...they kick @$$)
Route 2A east through Fitchburg...veer onto 225 (left)...right to stay on 225...right on Town Forest Rd...follow signs to parking...
