Humans trace their ancestry to animals that left the sea and moved onto land. Whales trace their ancestry to a group of mammals that left the land 60 million years ago and returned to the sea. In relatively more recent times, Cape Cod, Nantucket, and New Bedford were East Coast centers for the harvesting of whales. Today, the Cape is a major center for the watching of whales. Commercial sightseeing boats conduct whale-watching tours of 3 to 8 hours from piers in Provincetown, Barnstable, and Plymouth from April to November. In the spring whales can be seen off the Cape migrating from the south, and in the fall they can be seen migrating from the north. Whales commonly seen off the Cape include the humpback, minke, and finback. Right whales are sometimes seen in the fall and spring. Whales may often be seen from land at Province Lands Visitor Center and from Race Point Beach. But you will see the whales up closer from a boat—and they will get a chance to watch you.
