The Seals of Chatham Harbor

Chatham Harbor and its outer sandbars are a favorite haul-out for gray and harbor seals. At low tide you’ll see them up close on the bars — mostly gray seals (the big ones, with the long “horse-head” profile) alongside smaller harbor seals, especially in the cooler months.

Cape Cod is home to one of the largest gray seal populations on the U.S. East Coast — a genuine wildlife success story after decades of protection — and Chatham Harbor is one of the easiest places to see them up close. That same abundance of seals is why great white sharks visit Cape Cod waters in late summer.

What You’ll See on a Chatham Seal Cruise

On a typical one-hour cruise you’ll see seals up close on the sandbars, along with shorebirds, the famous Chatham break, and often ospreys overhead. It’s an easy, family-friendly boat tour that kids love — and one of the best things to do in Chatham on the water.
