🏆 Official Guide: Otter Brook State Park — A scenic recreation area managed by the U.S. Army Corps of Engineers in Keene/Roxbury, New Hampshire — featuring fishing (brook trout, rainbow trout, bass, perch), a boat ramp (no-wake), hiking trails through forest and wetlands, picnic areas with shelters, disc golf, and winter activities including ice fishing, cross-country skiing, and snowshoeing.

Otter Brook State Park is a quiet, nature-focused recreation area built around a flood-control reservoir in the rolling hills of southwestern New Hampshire. While the swimming beach is permanently closed, the park remains a valued destination for anglers (trout-stocked waters), paddlers, hikers, and winter recreationists. The wooded setting and diverse habitats make it an excellent spot for wildlife observation year-round.

💡 Pro Tip: The state stocks Otter Brook (upstream and downstream of the lake) with brook and rainbow trout, making this a prime fishing destination for fly anglers. The no-wake policy keeps the lake peaceful for paddlers — kayaking here is serene. In winter, ice fishing for perch and pickerel draws a loyal following. Always call ahead to confirm gate status — when the gate is closed, it’s walk-in only with no facilities.
