Beaver Brook Association is a mission-driven, privately held, non-profit organization dedicated to promoting the interrelationships in the natural world and encouraging the conservation of natural resources through education and land stewardship.

Beaver Brook Association is located on Ridge Road, Hollis. From US-3 exit 6 in Nashua, go west on NH-130 for about 6 miles. Bear right at the split and go to the stoplight at NH-122. Turn left and go about 1 mile. Turn right on Ridge Road and go about 1 mile to Maple Hill Farm at 117 Ridge Road, the Association’s headquarters. This parking area provides easy access to the trails south of NH-130.

For quicker access to the trails and ponds north of NH-130, continue past NH-122 about 1.5 miles to a large parking area on the right.
