Located in the towns of Dunbarton and Weare, the area is one of the oldest of the State’s public riding areas and one of the few in southern New Hampshire. A Federal flood control zone owned and managed by the Army Corp of Engineers, the NH Bureau of Trails leases the property on an annual basis. All of the trails and infrastructure were developed with volunteer labor from the Merrimack Trail Riders (MVTR) beginning in the early 1980s. Since that time, MVTR and the State’s Bureau of Trails have partnered to maintain the OHRV trails within the riding area. MVTR utilizes self generated funds and monies from the State’s Grant-in-Aid Program (GIA) to cover the cost of maintenance. The GIA monies are derived primarily from OHRV registrations. The area is closed as warranted by Army Corp. flood water retention requirements and mud season, (mud season is typically late winter to May 23rd).

Please report trail maintenance issues, with the trail name and closest mile marker, by clicking on the following names:

MVTR Trail Administrator: James Soucy

There is a considerable amount of work required throughout the year in maintaining the trails for use by all OHRVs (ATVs, Trail Bikes and UTVs). Volunteers are always needed and can offer their help with work parties by contacting the Trail Master or Administrator. For more on work parties, please visit here.

As a multi-use trail system, the trails are open to hikers, mountain bikers, horses, and dog sleds. Exercise caution and treat other trail users with respect.
