Mashomack Preserve
A large nature reserve in southeastern Shelter Island, with oak woods, tidal creeks and coastline crossed by trails, and dense osprey nesting grounds.
Mashomack Preserve is managed by The Nature Conservancy. It covers about 8 square kilometres, roughly a third of Shelter Island, and includes oak woodland, salt marshes, tidal creeks and nearly 16 km of coastline. It is one of the densest osprey nesting areas in the northeastern United States. The visitor center provides maps, and several loop trails of about 2 to 16 km run through the reserve; in spring you can see many migratory birds and ospreys. A donation is suggested for entry. Cycling and pets are not allowed. The preserve is closed on Tuesdays, and winter hours are shorter.
