October Mountain State Forest is Massachusetts' largest state forest (16,460 acres) offering a campground with 44 campsites, three yurts, and eight RV sites near Lee in Berkshire County.

The campground provides access to extensive hiking trails including the Appalachian Trail, plus fishing and non-motorized boating opportunities at October Mountain Reservoir and other ponds; note that RV sites lack hookups and advance reservations are required.

Campers should be aware of noise from a nearby power station and that firewood must be purchased on-site ($7/bundle, credit card only).
