Island Beach Ferry

Island Beach, located two miles south of Greenwich Harbor in Long Island Sound, is owned by the Town of Greenwich. The 3.9-acre island is managed by Greenwich Parks & Recreation, and access is via a seasonal ferry service that departs from Arch Street, across the harbor from the Delamar Hotel.

In addition to the beach, the island has plenty of shade from trees near the beach, a concession stand, a playground with swings, a lot of tables, and even locker rooms. Island Beach is a great place to find sea glass, but it is a rocky beach, so bring water shoes.

All ages are welcome, and tickets for Cruise to Nowhere can be purchased at the Arch Street Dock beginning at 10 a.m. Cruise to Nowhere takes place on Wednesdays in the summer, check the ferry schedule.

The Prudence is a historic vessel and 1 of the 3 original Maine steamboats still active today. It is also the country’s oldest working ship! Larger groups of up to 100 guests can ride the classic vessel for an experience of a lifetime!
