Beaver Brook Association has 2,187 acres of forest, fields, and wetlands in Hollis, Brookline, and Milford, New Hampshire. This 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. On this landscape is a network of over 35 miles of trails, which provides a quiet and contemplative setting for daytime excursions. Forest and wildlife management is practiced throughout the property to protect and encourage a diverse array of native species.

BBA also protects significant portions of two watersheds and has designated natural areas. We encourage the public to visit our gardens and trails, which are open from dawn to dusk seven days a week, and rediscover the natural world.


BBA is 57 years old so we are going to give you 57 hikes to do to stay healthy & calm.  See the list…
