map & guides

Beaver Brook Association is comprised of 2,187 acres of forest, fields, and wetlands in Hollis, Brookline, and Milford, New Hampshire. The land lies where the southern transitional forest meets the northern hardwood forest, creating a diverse landscape of interest to the naturalist and the hiker alike.

dog policy

Dogs are welcome at Beaver Brook, but must be leashed at all times and kept under control by their owner. There are no exceptions to this rule and enforcement will be referred to the Hollis Police Department. Beaver Brook is a carry-in and carry-out facility and this pertains to cleaning up after dogs and taking the waste home for proper disposal.

Trail users are encouraged to stay on marked trails leaving the land, wildlife and plant life undisturbed.
