From Keene, NH: Travel northeast on NH-9/Franklin Pierce Highway. The entrance to Otter Brook Lake Beach is located on the right, 2.8 miles past the junction of NH-9 and Washington Street. The entrance is marked by a large brown park sign and a gate with a booth.


Otter Brook Lake offers many recreational opportunities that everyone can enjoy. A sand swimming beach, ball fields, and a large developed picnic area are all open to the public in the summer. In the winter, cross country skiing is allowed on the lake and along the paths which surround it. Gentle walking trails provide access to the marshy inlet of Otter Brook and wildlife viewing there. Flush toilets are available along with a changing area. Picnic shelters can be reserved for group events online or by phone at 1-877-444-6777.

Other Information

Please note that pets are not allowed at Otter Brook Lake and that users must carry out what they carry into the park.
Swimming is only allowed in designated swimming areas and at one's own risk, as there is no lifeguard on duty.
