Time for everyone to migrate: Follow gray whales south to Los Cabos for winter

Every December through March, gray whales swim 8,000 km (5,000 mi) south from Alaska’s Bering Strait to the tip of the Baja Peninsula. Up to 6,000 whales swim past and stop close to the shore at several spots to give birth to their calves. Whale-watching boats—most of them pangas (small skiffs)—must get permission from the Mexican government to enter whale-watching areas.
