Board a dedicated whale watch vessel into Stellwagen Bank National Marine Sanctuary, where humpbacks, finbacks, and minkes breach and feed in spectacular proximity. One of the most thrilling wildlife encounters on the entire East Coast.
What to expect
You'll sail 30 miles out to Stellwagen Bank, a nutrient-rich submarine plateau that draws the highest concentration of whales on the Atlantic seaboard. Naturalists identify individual whales by name from a catalogue built over decades of research. Breaches, lunge-feeding, and tail-slaps are routine sightings. The trip runs 3–4 hours, giving ample time on the water without feeling rushed.
