There are Cozumel beaches and beach clubs both the north and south of town.
The town on Cozumel is San Miguel, but everyone simply calls it Cozumel. It is on the western side of the island and it faces the mainland of Mexico.
There are also Cozumel beaches on the other side of the island (the eastern side) and since the island is only about 10 miles wide it does not take long to get there. Swimming on the eastern side of the island can be dangerous since it faces the open ocean and there can be a very strong undertow and currents. We recommend swimming only at Cozumel beach clubs, and only in areas marked off as safe.
Just to the south of town there is a public beach called Playa Caletitas (photo below) with a beach club and restaurant.
Beginning about 7-8 miles south of town there are 4 Cozumel beach clubs right in a row.
Ocean, Carlos n Charlies, San Francisco and Paradise Beach

To the north of there are very few sandy beaches with easy entry into the water.
One Cozumel beach club north of town is called Buccanos, and another is called Playa Azul.
Buccanos (photos above) is a beautiful beach club with a swimming pool, a very good restaurant, lounge chairs, a sandy beach area, clean restrooms, etc. Mon.-Sat. there can be a lot of cruise ship people here so it can be crowded. Sunday is a great time to go. There is a charge to enter but you will receive "tickets" showing how much has been paid and what you have paid applies to any food or drinks you order. It's a great deal, and Buccanos is a Beach Club where you can stay all day if you wish.
