The closest to the Bridges Inn, and our personal favorite, is Richardson Park, on Swanzey Lake.
Open from Memorial Day through Labor Day, daily, 10 a.m. to 8 p.m. It's a shady beach with a nice view and water quality is generally considered good. There's no charge to get in and plenty of parking. Shown below, Richardson Park is for Swanzey residents only, including guests of the Bridges Inn.
Otter Brook Lake Recreation Area in Keene and Roxbury and Surry Mountain Lake Recreation Area in Surry (shown below) are operated by the Army Corps of Engineers. Both are picturesque, family-friendly places for swimming, picnicking, and canoeing. There's a sandy beach, roped-off swimming area and plenty of grassy areas to set up games throughout each park. There are also picnic tables and rest rooms.

In addition to directing Bridges Inn guests to places to swim, we can help you plan other activities to fit your particular interests.
