Offshore New England rock site near Appledore Island, with ledges, cracks, and boat-only access that depends heavily on weather and tide windows.
About Devil'S Glen
Devil's Glen is a boat-only cold-water dive off Appledore Island in the Isles of Shoals, with a rugged ledge-and-crevice profile that rewards slow, deliberate navigation. Expect exposed offshore conditions, rock structure full of cracks and overhangs, and a site that can go from workable to rough when wind or tide builds. Clearer windows and steady buoyancy matter more than depth alone.
