Whale-watching

Surround yourself with ocean blue and wait for the fins and tail

Word to the wise: Special sunset tours are available. The highlight of these romantic cruises is when the sun dips past the horizon and whales seem to spout on cue.
The ship that chased Moby Dick set sail from Nantucket, 100 miles south of Boston. But the tours setting off from the New England Aquarium won't be captained by a madman, and the whales are meant to be watched, not killed.

Voted the best in the city, the whale-watch tours operated by the Aquarium whisk adventurers out to sea on the 'Voyager III', a high-speed catamaran with naturalists and educators onboard. The boat heads to Stellwagen Bank Marine Sanctuary, where whales, dolphins, and sea birds come to feed. You could sight several species of whales, including humpback, finback, pilot, and right whales. Dolphins, too, if you're lucky.
Best of all, whale sightings are guaranteed. And if no whales make an appearance, passengers will get a complimentary whale-watch ticket to use in the future.
