Great Harbor Wildlife Management Area on the Connecticut coast protects salt marsh and tidal wetland along Long Island Sound — one of the most urbanized coastlines in America. Connecticut’s remaining salt marshes filter water, buffer storms, and provide nursery habitat for bluefish, striped bass, and winter flounder. These marshes are threatened by rising seas — Connecticut has lost over 15% of its tidal wetlands since 1880.
Things to Do
Birdwatching (osprey, egrets, herons, shorebirds), saltwater fishing for striped bass and bluefish, crabbing, and kayaking through the tidal channels. One of the best coastal wildlife viewing spots in the Guilford area.
Birdwatching for shorebirds, herons, and ospreys, saltwater fishing, kayaking the tidal creeks, waterfowl hunting (seasonal), and observing a coastal ecosystem under pressure from sea-level rise and development.
