Gray days ahead in Monterey

Grey whale migration is a rare scenery, thousands of gray whales, many with calves in tow, swim by this part of the Pacific coast as they migrate from the warm waters of Baja California to their summer feeding grounds in the Bering Sea. Come winter, they pass by again on the swim south. The entire roundtrip route clocks in at about 12,000 miles, making gray whales among the longest migrators of animal kingdom. Because they travel close to the coastline, it's also one of the few whale migrations you can see from shore.
