This place is a lot of fun with pretty much every kind of riding (including road, if that's also your thing) except for huge technical climbs. For a state park in the northeast, it is enormous and the listed 15 miles of trails is way low. For context, the Landmine Classic, an annual MTB race, follows a 25-mile route of two large loops, one on each side of the park, and it doesn't repeat any trails as far as I know. It also doesn't include close to all the trails. All told, I would guess they have closer to around 50 miles of trail, which NEMBA and The Friends of Wompatuck work together to do an amazing job of building and maintaining. If you're on the south shore of Massachusetts, this is definitely one of, if not the, premier trail networks to visit.
EDIT: BTW, Friends of Wompatuck have created a very handy interactive map which you can download to your phone and use to view some routes and your location on the map. I used it to follow some of the Landmine Classic route and it was extremely helpful, especially considering how many trails there are. Here's the link: https://friendsofwompatuck.org/map/
