Most of the Woodlands trails are singletracks. The most scenic wind through the woods on ground that's high above the Mashpee River. The views are spectacular. The trails twist through the trees climbing and descending short hills. They are very pleasant to ride, the only downside being that there are too few of them.
In all there's about 4 miles of trails here. The solution - ride them in both directions. These scenic trails look entirely different in the opposite direction.
The Map link above is borrowed from the Trustees of Reservations. This TTOR property in Mashpee is currently closed to bikes. However all of the Town of Mashpee land welcomes mountain bikers. Indeed, local bikers do most of the trail clearing and trash pickup. Cape Cod NEMBA is working on a map of it's own that will clear up this confusion.
Expect to spend about at least an hour and a half exploring Mashpee Woodland's trails. More if you bring a lunch and stop at one of the many benches overlooking the river. In warm weather you may also want to jump in the river for a refreshing swim. But mostly you'll be there to explore and enjoy the trails.
The parking area is isolated. It's deep in the woods at the end of a short dirt road. You'll see a sign on Quinaquisset Ave. A little further down Quinaquisset there's a smaller roadside parking area.
Mashpee Woodlands trails here are rarely too difficult to ride for newer riders. Kids on small wheeled single speed bikes might have to walk a few of the hills but otherwise the trails are fine for family rides.
You'll enjoy the Mashpee Woodlands. I certainly do.
