Merrimack Valley NEMBA builds, stewards and rides trails in the northwest quadrant of metro-Boston. This includes the State Parks like Lowell-Dracut-Tyngsboro State Forest and Great Brook Farm State Park, as well as local conservation lands such as Russell Mill in Chelmsford. Our group is passionate about riding and taking care of the trails we ride. We also offer skills classes and have lots of ways for riders to get involved. Our big annual event is our MTB Adventure ride at Great Brook.

Come ride with us and help make great trails to ride. Below are some of the many events we put on.
