Connecting people to nature is what we do. Environmental education programs are offered for all ages year-round!


Come for a hike on our 35 miles of maintained trails. Be sure to view the map for trail usage information. 


Enjoy 13 beautiful gardens, a wisteria arbor, a demonstration compost court, and a wide variety of flowers and shrubs.


The Beaver Brook office at Maple Hill Farm is located 1 mile off of Rt. 122 in Hollis NH. Beaver Brook trails may be accessed from several different public roads. Our trails are open to the public, 365 days a year, from dawn until dusk. When planning your hike, consult the map first.


Beaver Brook relies on contributions from our visitors and the community to maintain our lands, trails and the many historic buildings used for environmental education programs.
