The Premium Marsh Conservation Area is a part of the 65-acre Premium River-Pine Brook Wetlands Complex, which lies on the borders of the Village of Larchmont, the Town of Mamaroneck, and the City of New Rochelle. This is an 18-acre area, eight of which are tidal wetlands. This wetlands complex is a New York State designated "Significant Fish and Wildlife Habitat" and includes a range of different habitats from the fresh waters of the Pine Brook to the salt waters of the Long Island Sound.
The entrance to the Premium Marsh Conservation Area is at the bottom of Dillon Road on the left hand side. Please park just beyond the entrance on Pheasant Run. The marsh can also be seen from Lorenzen Field and Willow Park in Larchmont Village.
