Warner Trail – Sharon, Massachusetts The Warner Trail stretches more than 30 miles from Sharon, Massachusetts, to Diamond Hill State Park in Cumberland, Rhode Island, making it a long-distance point-to-point hiking route. The terrain is hilly and occasionally rugged with ledges of metamorphic rock and granite, offering a moderately challenging experience. The trail explores both public and private lands, including the Moose Hill Audubon Sanctuary, F. Gilbert Hills State Forest, and Minnehaha Falls. Starting at 207 Edge Hill Rd in Sharon, the access route is a steep climb that crosses through Town Conservation Land and connects to the first section of the Warner Trail. The route winds through a primarily suburban landscape punctuated by significant pockets of rural conservation land and state forest.
