The path is great, some downhill and can be taken either way. Just watch out, about 1/4 of the way in, there is a stream with rock in it. Walk or ride over, its still a fun trail. Empties out onto Tinkham road.
Park at the Minnechaug Regional High School Senior Lot (After school hours, car will be towed if you park durring school time). Bike To the left side of the track and bear left when the option is available. After a cement path there will be an opening in the woods to the left. Take that.
