Narragansett Trail official route

The Narragansett Trail in Connecticut is a multifaceted trail that passes thorough rich forestland and active wildlife refuge areas. The trail follows and crosses several brooks, traverses wild ravines, and passes five ponds and lakes. The trail offers many panoramic vistas along the way, including those from the summits of Lantern Hill and High Ledge. On a clear day, hikers may be able to see all the way to Long Island Sound. The trail joins the Pachaug Trail in Pachaug State Forest; it also passes near The Nature Conservancy's Gladys Foster Preserve, and offers opportunities for loop hikes where it connects with other CFPA trails.
The Narragansett Trail continues into Rhode Island at Camp Yawgoog and that section is maintained by the Appalachian Mountain Club. Along the border the trail shares footage with the Tippecansett Trail. The original 1932 route continues on yellow-blazed trails in Rhode Island maintained by the local chapter of the Appalachian Mountain Club. The club is actively working on restoring the original route all the way to Worden Pond. The trail through the Audubon Long Pond Preserve is considered by some to be the most challenging hike in Rhode Island and one of the most beautiful trails in all of New England. Note that Audubon does not allow runners, dogs, or bikes on the trail through their preserve.

Longer backpacking trips can be achieved by linking the Quinebaug, Pachaug, Nehantic, and Narragansett Trails. Four overnight shelters in the CT State Forest can be used by backpackers on a first-come, first-serve basis.
