Dear friends,
In support of the directives issued by the governors of Massachusetts and New Hampshire asking their citizens to stay at home and in direct response to the request of the Director of Emergency Management in Hollis to help to control crowds that could lead to an increase in the spread of the virus, Effective immediately the Beaver Brook hiking trails in Hollis, Brookline,
and Milford are closed to the public until further notice.
We certainly regret the need to do so. In normal times we welcome all visitors to explore the trails at Beaver Brook; but these are obviously not normal times. We have been advised that the unusually large crowds of people who have flocked to the Ridge Road, Wildlife Pond, and Diamond Casting trailheads have posed a greater risk of transmission and placed an additional
burden on Hollis’ already short-staffed rescue personnel. At a time in this pandemic when the need for their services is expected to increase dramatically over the next two weeks we cannot risk their being called to render aid to a hiker.
We apologize for encouraging you to come here to hike when it has rapidly become inadvisable to do so. Physical activity like hiking and immersion in nature are and always will be therapeutic and good for body and soul, but doing so at this time should not be allowed to contribute to the spread of this highly contagious virus. The trails will still be ahead of us when
this pandemic is behind us. Thank you for understanding the responsibility of Beaver Brook to do our part to slow the spread and thank you for doing yours.

Thom Davies
Volunteer Executive Director

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.

We recommend jog strollers or child carriers on the trails. Also obtain a map on this website or at the kiosk near trailheads.

1) At Maple Hill Farm 117 Ridge Road –the Gardens and the Wildflower trail are accessible by rugged stroller.

2) Parking at the lot on route 130 across from Diamond Castings, the Beaver Brook trail is accessible and flat for a while.

3) Park at the Wildlife Pond parking lot on Route 130, (route 130 1.7 miles west of route 122). Take “Dam Road” –it has one his but is feasible for a strong parent and a rugged stroller and will bring you to the big Wildlife Pond.

4) The Potanipo Rail trail accessed on West Hollis Street is flat and will lead you to a large “Great Meadow” wetland. There is a large parking lot here near the junction of Worcester Road and West Hollis Road and adjacent to the Nissitissit River.
