Rhode Island's highest point is not a terribly difficult climb. The route finding is easy, the distance is minimal, and the elevation gain unremarkable. The view from the summit is ... blocked by the trees.
Jerimoth Hill, all 812' of it, is in western Rhode Island, not far from the Connecticut state line. State Route 101 crosses the hill near the summit, so the final leg is an almost level trail not more than a few hundred yards long. The summit is marked by steel ammo canister - I didn't add my name. Nearby are some storage sheds and what I assumed were telescope mounts - Brown maintains the site as a potential observatory.
Until recently, this was one of the more difficult high points to reach, as the the owners of the adjacent land weren't keen on visitors, but now the summit is marked on the highway and the trail is open to all. There are residences nearby, visible through the woods.
