It can be difficult to comprehend the magnificence of marine animals without seeing them up close in their natural habitat. If you’re on Cape Cod or the Massachusetts islands, there are numerous opportunities to do just this, by participating in a whale watch or seal tour on the Atlantic Ocean, Cape Cod Bay, or Nantucket Sound. 

Whale Watching in Cape Cod: Tips and Essentials

Tours typically run from April to mid-autumn. Most whale watches on Cape Cod depart from Provincetown; at the very top of Cape Cod, it’s situated near the Stellwagen Bank National Marine Sanctuary, a preserve off Cape Cod Bay that serves as a prominent feeding ground for whales during much of the year, making it one of the best places around to witness whales. You’ll find seal tours located in more locations around Cape Cod, with many around the Lower and Outer Cape (the towns along the easternmost side of the peninsula)

To enjoy yourself on a tour, be sure to bring layers of clothing, as it can be 10-15 degrees below land temperature out on the water – and very windy! Other essentials include sunscreen and plenty of water. If you bring a pair of binoculars, you’ll have the advantage of scoping out these majestic animals up close.

On your trip, you may see Humpback, Minke, Right, Pilot, and Finback whales, all of which call the waters off New England home for at least part of the year. These tour operators employ expert naturalist and marine biologist guides, who can tell you the species you’re looking at, whether it’s an adult or juvenile, the species’ unique habits, and endless fun facts. If a particular whale is a known visitor, your guide may even be able to tell you its name!

One of the best parts of taking a boat tour where you’re interacting with nature and animals, is that you never know exactly what you’ll see. Nature’s potential to surprise – in concert with each of these tour operators’ exceptional customer service, top-notch guides, and safe vessels – make an adventurous voyage at sea a highlight of any trip to Cape Cod.  Below are nine of the best boat tours off Cape Cod for experiencing awe out on the water.
