The park is the Faro Celarain reserve at the far south end of Cozumel, past Palancar, not the hotel-zone strip. You pay a park admission, drive a long internal road, climb the lighthouse, ride a lagoon boat called El Tatich if it is running, and spend the rest of the time on the beach or the trail. What it is not: Mr Sanchos or Paradise Beach. Those are day-pass clubs with a buffet. Punta Sur is conservation land with a restaurant or two inside. Food, kayaks, and snorkel gear sit outside the gate ticket. The park's own English page lists the lighthouse, navigation museum, lagoon boat, hammocks, beach chairs, and trails as part of general entrance.
