Stellwagen Bank, Massachusetts whale watching
Stellwagen Bank rises off the tip of Cape Cod like an underwater plateau, and from late spring through fall it fills with humpbacks lunging through bait balls — the kind of breaching, flipper-slapping show that makes a whole trip. Boats run from Provincetown, Boston, Gloucester and Newburyport, and a few hundred wooded sites at Nickerson State Park make a comfortable Cape base between sailings.
Typical season
Early May through October
Whales to look for
Humpback whale, Fin whale, Minke whale, North Atlantic right whale (spring)
Where
Stellwagen Bank National Marine Sanctuary (NOAA) — off Cape Cod
