About
Hammonasset Beach State Park is a Connecticut State Park campground with 548 sites near Madison. Connecticut's largest public beach park campground, with over 2 miles of sandy beach, a camp store, and the Meigs Point Nature Center. Peak season runs late May through mid-October. Electric and water hookup sites available (confirmed via live per-site amenity data, not just the site-type name). Reservable through Connecticut State Parks' own ReserveAmerica contract (connecticutstateparks.reserveamerica.com), up to 11 months in advance. Connecticut's camping system is uniformly reservation-based - no first-come-first-served-only campground was found in this state's system.
Fees
$20/night (standard) or $35/night (electric+water) for CT residents, $30/$45/night for non-CT residents (portal.ct.gov DEEP fee schedule); $70/$80 rustic cabin rate also available (8 cabins). Plus a ReserveAmerica reservation processing fee. Pets are NOT allowed here - Connecticut DEEP's own policy: "Pets are prohibited in State Park camping areas, but permitted at State Forests." (ctparks.com/camping, confirmed live.)
