Discover our Monomy Island Seal Tours & More!

Monomoy Island Excursions is a family-owned and operated business in Harwich Port, Cape Cod, Massachussets. For over 10 years we’ve been taking people out to Monomoy, a barrier island and wildlife refuge off the coast of Chatham, MA. Explore where thousands of seals have made their home.

While seals are the main attraction on our cruise, there is a lot to see! We visit Wychmere Harbor, in Harwich Port. This is one of the most scenic harbors on the Cape! We also stop in to Stage Harbor in Chatham, where you get a close up view of Stage Harbor Lighthouse and see Chatham Lighthouse. Not to mention the combination of large yachts, small sailboats, and various fishing boats that fill each harbor. You get a real taste of the sea life on Nantucket Sound.

We run seal cruises several times a day, generally lasting 1 1/2 hours. While we see lots of harbor seals and gray seals, Monomoy is also home to hundreds of species of birds and other wildlife. There is a trained naturalist on board who narrates the tour and can answer questions about the wildlife as well as the history of the island and the historic Monomoy Lighthouse.
