Belle Isle Marsh is one among several final remnants of salt marsh throughout the Boston Basin. It is located within the Boston city limits and is therefore somewhat unusual. This site contains a salt marsh, tidal creek, salt pans, a Common Reed stand, and upland parkland on the periphery of Boston Harbor.

This is an urban salt marsh with lively and representative flora and fauna. Used by school groups extensively.
