Cozumel, Mexico

Known for: World-class scuba diving, cruise port, calm snorkeling coves

Cozumel is best known as one of the busiest cruise ports in the Western Caribbean, but it’s also a legitimate stand-alone destination for anyone serious about scuba diving: the Palancar and Columbia reef systems are some of the best diving in the Caribbean.

For cruise passengers with just a few hours in port, Dave typically recommends a beach club day pass over a packed excursion: it’s the more relaxing option for families with young kids.
