Monomoy Island Seal Cruise & Barrier Beach Wilderness

Glide through Wychmere Harbor and Stage Harbor aboard a small vessel to wild Monomoy Island, a federally protected barrier beach hosting one of the largest grey seal colonies on the Eastern Seaboard. An untouched wilderness most visitors never reach.

What to expect

Departing from Harwich Port's scenic Wychmere Harbor, the vessel threads through Stage Harbor in Chatham before reaching the open sandbars of Monomoy Island. Hundreds of Atlantic grey seals bask within arm's reach of the boat, utterly unbothered by human presence. The naturalist guide explains the ecology of the refuge and points out shorebirds, terns, and migrating raptors along the way. The landscape — wind-sculpted dunes, empty beaches, and glittering tidal flats — is arrestingly beautiful.
