The Sunapee-Ragged-Kearsarge (SRK) Greenway Trail is a 75-mile loop of hiking trails in central New Hampshire. The Greenway Trail System circles the Lake Sunapee area and connects Sunapee, Ragged, and Kearsarge Mountains.

The Greenway’s mission is to create and maintain a forever green, great circle of trail corridors and conserved lands providing walkers with minimally-developed access to the mountains, lakes, vistas, and historical sites of the Lake Sunapee Region.
