Blackstone River Canal
Heritage State Park
The towpath that parallels the Blackstone River and Canal is a fantastic place for beginners just getting their feet into mountain biking. It provides a scenic and relatively non-technical ride until one reaches the lower Goat Hill trail toward the middle of the park. Once you cross the lock and turn left, this section of the trail provides some rock gardens so one can begin learning to pick a line through rock gardens, but the path is wide, so it's not too intimidating. If you are looking for a cardiovascular workout, you can head straight across the lock on the upper Goat Hill trail. I personally wouldn't recommend riding it from this direction, as it is steep and technical, and would be a miserable hike a bike. Instead, I would ride to the southern end of the lower Goat Hill trail and turn back north, forming a clockwise loop back to the lock. You will probably still end up hiking your bike down the trail, but it is much better than trying to ascend it.
