Mink Brook Nature Preserve, just south of Hanover and managed by the Hanover conservancy, is a 100-acre nature preserve of white pine and hemlock, and the home of brook trout, bears, and lots of flora. The property has two brooks: Trout Brook, which winds northward to join Mink Brook, and Mink Brook, a tributary of the Connecticut River. Two trails offer a variety of walking terrain. Leashed dogs are allowed. Fishing is permitted; trapping, hunting, and fires are not allowed.
