Ashland Town Forest
At 616 acres and incorporating parts of Ashland and Framingham ATF's 7+ miles of trails offer hardwood forests, stone outcroppings and wetlands. The trails can be wet in early spring, but dry out quickly.
Local mountain bikers that ride the ATF refer to it as a hidden gem. It's great place to get 8-10 loopy miles.
It's fun with a few punchy climbs but mostly flat.
ATF is a great place to ride. Explore it once, and you'll be back.
