I WONDER - Do Whales Migrate?

Whales are known for their extensive migrations, traveling thousands of miles annually to reach optimal feeding and breeding areas. Gray whales, in particular, embark on one of the longest migrations, covering up to 12,000 miles round trip between the Arctic and Mexico. These journeys often bring whales close to shore, allowing for whale watching opportunities.

During their migrations, how do whales typically travel in relation to the shore?

What activity allows people to spot whales during their migrations?
