Cozumel has more excursions than pretty much any other port of call. But we didn’t actually do any of them. We had some friends there were staying in town, so we hooked up with them. We spent part of the day at Chankanaab Park. Then we headed in to town for shopping, and dinner before returning to the ship. I would have liked to have seen some of the Mayan ruins.

Here are the ones listed in the Carnival shore excursions book. Not all excursions will be available for every cruise, or during every time of year. Other cruise lines probably offer the same or similar excursions.
Excursions can either be booked through the cruise lines ahead of time, or while on ship. Booking the excursions directly with the operators is also an option. This can save you money, but involves risk if there is a problem.
