Monomoy Island is an 8-mile-long sandy island off Cape Cod in Massachusetts, located to the southwest of the mainland from Chatham. Due to tides and shifting sands, this charming island, known for the adorable seals that visit it, occasionally connects to the mainland.

Monomoy Island, Massachusetts, is inaccessible by car, which is part of what makes it special. The most convenient ways to reach the island, home to Monomoy National Wildlife Refuge, is via water shuttle and by taking an organized seal-watching tour.

Even though you cannot drive to Monomoy Island, read on to find out about how to reach it, our travel tips, the best time to visit and things to do and see once you reach Monomoy Island.

Can you drive to Monomoy Island?

You cannot drive to Monomoy Island as it is inaccessible by car. If you are driving to Cape Cod and wish to visit the island, you will need to park your car in Chatham and travel via water shuttles or hop on a boat operated by one of the popular seal-watching tours.

There is no bridge that connects the island to the mainland, and there are no ferry companies that travel from the mainland to Monomoy Island. The only travel option you will have to visit the island are chartered tours.

Monomoy Island Ferry organizes tours to the island from Chatham. Beachcomber Boat Tours gives tours of Pleasant Bay with customizable cruise options in the area.

As a third option, Outermost Adventures provide beach shuttles, seal-watching cruises, tours and fishing charters as Monomoy Island is also known for its fishing opportunities.

You can also opt for companies that hail from Harwich, such as Monomoy Island Excursions.

To book tickets, check these companies' websites for updated prices and how to contact them via phone to secure your booking as these are small companies and their operations are not as big as some ferry companies.

While not accessible by car, this beautiful island is still worth a visit. North Monomoy Island and South Monomoy Island are home to the beautiful Monomoy National Wildlife Refuge, which attracts tourists from all over the US with its fascinating seal and bird-watching opportunities, and to the historic Monomoy Lighthouse.
