"These trails guide visitors around the watermen's crabbing shacks built on stilts in Tangier Harbor, to navigate the saltwater "guts" that separate the island, or to visit "the Uppards", a marshy island just to the north of Tangier that used to have a sizable community until it was abandoned in 1928.Immediately to the east of Tangier, also a kayak paddle away, is Port Isobel, a small island owned by the nonprofit Chesapeake Bay Foundation, which operates an environmental study and retreat center there; on nautical charts, this bit of land is called East Point Marsh.
