Is there anything more fun to do in the summer than get out on the water? Well, if you’re in New England you know that being on the water on a whale watching tour is even more fun! Here in Massachusetts, we’re almost guaranteed whale sightings as just off the coast is the Stellwagen Bank Marine Sanctuary – the summer home of humpback whales, fin whales, minke whales and North Atlantic right whales. The national sanctuary has been named the best place to see marine life by USA Today. Spending a day whale watching in Cape Cod Bay is a great opportunity for enjoying these amazing marine mammals in their natural habitat. I’ve been out with Captain John Boats twice and highly recommend it.

Stellwagen Bank National Marine Sanctuary
The Stellwagen Bank sanctuary is part of the Gulf of Maine and is an incredibly rich marine habitat. What began as just an important fishing ground is now an active fishing, shipping and recreational area. The Gulf of Maine’s importance as primary feeding grounds for marine mammals has led to this being a top destination for whale watching on the East Coast.
Former director Craig McDonald describes the sanctuary:
“The Stellwagen Bank National Marine Sanctuary stretches between Cape Ann and Cape Cod at the mouth of Massachusetts Bay. Virtually the size of the state of Rhode Island, the Sanctuary was established in 1992 because of its remarkable biological, geological, oceanographic and cultural features.”

Whale Watching in Massachusetts: whales and more!
Most of the marine mammals you’ll see while whale watching in Massachusetts will be the humpbacks. These enormous whales (as big as a school bus!) are stunning and will put on quite a display. You will likely see behavior like bubble net feeding and fin slapping. Bubble net feeding is fascinating to watch. From the boat you’ll see a sudden disruption on the surface of the ocean. What is happening is that under the water the whale is releasing a stream of bubbles to corral small fish. Then the whale surfaces, gulping everything in its way before expelling the water through its baleen plates, leaving just the fish to swallow.

The naturalist on board the boat can usually identify individual whales from the marking on their tail flukes. The whale pictured is known as Pixar. The sanctuary keeps track of these gentle giants in order to assess the health of the population.
Two other species of whales frequent the sanctuary but both are endangered. The fin whale (also known as finback whales) is the second largest whale in the world growing up to 75 feet long. It also feed using the baleen plates to strain its food. The last resident of the area is the Northern Atlantic right whale. This is a critically endangered species and is the focus of much of the conservation work done by NOAA and the marine sanctuaries.
Other wildlife to expect while whale watching in Cape Cod, Massachusetts
If you’re lucky you might see common dolphins, tuna, and sea turtles. On my last trip the crew spotted bluefish and tuna, but I was on the other side watching the antics of Pixar, a large humpback. Three species of sea turtles feed and migrate through these waters.
Keep a lookout for seals. Gray seals and harbor seals are common in the waters of Cape Cod and are fun to watch. And where you find seals, you MIGHT find sharks! The onboard naturalist will be quick to point out any they see, especially if it’s a great white shark!.
For more detailed information on the wildlife you’ll see, check out the Stellwagen Bank website.

What to Expect on Whale Watch Excursions
A whale watching excursion is usually about 4 hours long. From most locations it’s an hour trip to get to the area where the whales are feeding. The company knows generally where the whales are located. There is a small snack bar on the boat selling coffee, muffins, and light meals, but you can bring your own snacks if you want. Just be sure to dispose of all your trash responsibly.
The trip to the sanctuary through Cape Cod waters is generally easy, but depending on the offshore water conditions you might experience some seasickness when the boat stops to enjoy the whales. If you tend towards motion sickness, I’d recommend taking a medication like bonine or non-drowsy dramamine before the boat ride.


Everything You Need to Know About Whale Watching in Massachusetts
The whale watch season in Massachusetts runs from the beginning of May to late October.
Wear comfortable shoes and bring a light jacket or windbreaker. Even on the hottest day it gets cool when you’re out on the Atlantic Ocean.
Bring binoculars. Not so much for the humpbacks which are not shy and will put on a show for you, but with the binoculars you’ll be able to see some wonderful ocean birds while you’re out. Shearwaters, Storm Petrels, Jaegers, and lots of other birds are common in the sanctuary.
I recommend going with a certified whale watch operator. There are strict guidelines for observing these animals in a safe and responsible way. Check Whale SENSE for a list of companies following sustainable practices in whale watching.
Whale Watch Tour Operators in Massachusetts
There are many tour boat operators running responsible whale watching trips in Massachusetts. I have linked to those passing Whale SENSE standards.
- If you’re in the south shore you can take a Captain John boat out of Plymouth harbor.
- On the north shore, tours leave from Gloucester and Newburyport (Newburyport Whale Watch).
- From Boston head to the harbor for a New England Aquarium Whale Watch
- And if you’re visiting Cape Cod the best locations are Hyannis (Hyannis Whale Watcher Cruises) and Captain John from Provincetown harbor.

If going out on your own, check out the See a Spout website which gives a simple outline of things to do if you see whales while boating and ALWAYS make sure to follow NOAA’s guidelines:
Guidelines for Safe Whale Watching from the Stellwagen Bank National Marine Sanctuary website.
- Do not chase or harass whales. That is against the law and can lead to serious fines. Learn about safe boating around whales through See A Spout, an education program developed by NOAA Fisheries, Whale and Dolphin Conservation, and the sanctuary or visit the New England marine life viewing guidelines from NOAA Fisheries.
- Post a lookout to watch for whales. These animals may not sense your approach when feeding and may pop up right in front of you. Look for hovering birds; they know when whales are approaching the surface.
- Keep a slow speed in areas where there are whales or other vessels watching whales. If there is one whale present, there may be others. A collision with a vessel can be life-threatening for the whale and may do significant damage to a boat. Use the free Whale Alert app to receive notifications of right whale sightings, regulations, guidelines, and other timely information.
- Do not discard litter overboard. It may be ingested by the animals and cause harm.

Thanks for sharing your experience and letting us know what to expect.
Sounds like an amazing day!
Fantastic seeing whales and great tips too. They are magnificent.
Thanks for an informative article. Did you find that the whale watching tours were wheelchair accessible? That would be great information to add to your post!
That’s a great question. I’ll have to look into this as I hadn’t asked of the company. Thanks!
Wow! What a great experience to get so close to these huge whales. Your pictures are fabulous! Thanks so much for sharing!
This is definitely something I want to do someday, so I’ll keep this in mind next time I’m in Massachusetts! Thanks for this great post!
Wow, this looks amazing! What a cool experience.
I hope everybody follows the tips, especially the one that talks about discarding the unnecessary things in the water.
Great read, thanks for sharing! Also, didn’t know there was a whale watching app– so cool!
