If you had to pick one spot? The Bahamas. Clear, shallow, warm water. Tons of fish. Sandy bottoms for sleeping dolphins. (They sleep with half their brain awake, by the way. Weird flex.)
Or the South Pacific, near Fiji or Hawaii. Spinner dolphins love the deep channels and coral reefs. They perform aerial somersaults for fun. Extreme athletes.
And don’t forget Monterey Bay, California. Cold? Sure. But giant schools of anchovies? Yes, please. Bottlenose dolphins feast there all year.
