Take a self-guided tour of Nantucket Island’s ruggedly beautiful coastal environment where deer, raptors, seals, and shorebirds play. Made up of a pair of long peninsulas, Coskata-Coatue (pronounced “co-skate-uh coat-oo”) Wildlife Refuge is both a popular warm-weather destination and a wild, remote barrier beach. Beach hours are 9 am to sunset: access is not guaranteed.
