When you’re going out for a whale watch, you want a fast boat, a knowledgeable naturalist, and a crew that knows where the whales hang out. You get all three at Hyannis Whale Watcher Cruises.
Because of its central location, this harbor will probably be closer to your lodging than Provincetown. What you save in drive time, you make up in a longer trip on the water. (In other words, the Dolphin Fleet Whale Watch outfit is closer to the whales.)
