Hammonasset Beach State Park is Connecticut’s largest shoreline park, stretching over two miles of sandy beach along the shimmering waters of Long Island Sound in the charming coastal town of Madison. With 558 campsites (accounting for roughly 40% of Connecticut’s state park camping capacity), a 3.4-mile paved multi-use trail, saltwater fishing, the interactive Meigs Point Nature Center, and a calendar packed with family-friendly programs, Hammonasset delivers Connecticut’s premier beach camping experience. Whether you’re looking for a classic New England beach day or a seaside camping getaway just 90 minutes from New York City, this is the destination.
Beach & Swimming
The park’s defining feature is its two-mile stretch of sandy shoreline along Long Island Sound — the longest public beach in Connecticut. The beach is divided into several access points, each with parking, restrooms, and picnic areas. The water is calm and shallow in most areas, making it ideal for families with children. Lifeguards are on duty seasonally, though swimming is at your own risk when lifeguards are absent.
The beach faces south toward Long Island Sound, providing stunning sunrise and sunset views over the water. The Willard’s Island section of the park is particularly scenic, with salt marshes, tidal pools, and views that feel more like Cape Cod than suburban Connecticut.

The center runs guided nature walks, summer programs, and educational events throughout the year. It’s a perfect rainy-day activity or a way to enrich a beach visit with learning about Long Island Sound’s marine ecosystem.

Birdwatching
Hammonasset is one of Connecticut’s premier birding destinations, with over 200 species documented. The park’s salt marshes, tidal flats, and shoreline create ideal habitat for shorebirds, waterfowl, and migrating songbirds. Spring and fall migrations bring waves of warblers, plovers, sandpipers, and raptors through the park. In winter, the Point hosts rare visitors like snowy owls and harlequin ducks. The park is designated as an Important Bird Area by the Audubon Society.
