Oh, yet another place I haven't been to!
My local rides are Hale Reservation and Noanet Woodlands in Dover/Westwood, as well as a small place called Lowell Woods in Westwood. But it got me thinking, where have I been? After some thought, I realize how incredibly lucky we are to be in Massachusetts and how many places we do have. Here goes (and I'm sure I'm missing some, and some are places I've only ever gone once and maybe 20 years ago, and some -like World's End -I don't really consider mtbing. These are all in Massachusetts, and I've been to other New England states mtbing, but less so):
Lowell Woods
Hale Reservation
Noanet Woodlands
Rocky Woods
Noon Hill
Adams Farm
Framingham State Park
Dedham Town Forest
Dogtown
Ravenswood Park
Needham Town Forest
Cutler Park
Weston College Land
Land Locked Forest
Otter River State Forest
Ware River Watershed
Harold Parker State Park
Wompatuck State Park
Callahan State Park
Great Brook Farm State Park
Borderland State Park
Hopkinton State Park
Bradley Palmer State Park
Willowdale State Park
F Gilbert Hills State Park
Wilson Mountain Reservation
Middlesex Fells
Upton State Park
Nickerson State Park
Franklin State Park
Wrentham State Forest
Lynn Woods
Borderland State Park
The ones I want to mtb next have to be Ames Nowell (hiked in there, just never got around to cycling) and Myles Standish (similar). I'd also like to try Ridge Hill in Needham and Needham Conservation land.
But my local rides are definitely Hale/Noanet and Lowell Woods. It's hard to say which place I like the best, but I do enjoy Needham Town Forest and had I not overcycled it, Land Locked Forest in Burlington. Great Brook Farm State Park is also one of my favourites, but tends to be pretty busy these days. Rocky Woods is very pretty too. Cutler Park also has its appeal with the "back" loop, but the main loop trail you cycle on has too many people walking dogs there for me.
