At last! a properly marked and maintained trail on Cape Cod! Of course the trail and section are newly opened and sponsored by the Wequasset Inn, but at least there were nice, new, clear signs showing the way through the bulk of the 42 acre property via the main trail, and the spur leading to two new observation benches overlooking a steep declivity to the estuary variously known as 'Monomoy River' or (less euphonically) 'Muddy Creek'. This short river is surprisingly wide, a good place to kayak, and brilliantly blue on ths chilly morning I visited it. The trail leads through sparse but attractive second-growth woodland, a short stretch of power-line easement, and is essentially level and easy. It has been nicely demarcated by small tree trunks alongside. The whole hike takes under an hour and is pleasant, though not especially challenging. Congratulations, Harwich.
By the way, the introduction talks about Monomoy Island, which is nowhere near Monomoy River. The River is reached by taking the Bay Rd. exit just east of the intersection of Rtes. 39 and 137 in East Harwich, crossing Church St., and looking for the small, signed parking area on the right a few hundred yards beyond. The River opens into Pleasant Bay, a large estuary on the eastern shore of the Cape.
