A nature trail through the lagoon and wetland ecosystem at Cozumel's southern tip, within the Punta Sur Ecological Reserve. The reserve hosts American crocodiles in the lagoon, abundant bird life, and a small Maya lighthouse ruin. A coastal lookout tower provides views over the Caribbean.
Punta Sur Ecological Reserve occupies the southern tip of Cozumel island, reached by a paved coastal road roughly 40 minutes by rental car, taxi, or scooter from San Miguel de Cozumel; there is no public transit to the reserve, and an entrance fee is charged at the gate which also covers access to the beach club near the lighthouse. The main nature trail is a flat 3 km loop with no elevation gain and no technical difficulty, running along a mix of paved sections and packed dirt paths through coastal wetland and lagoon habitat. Shade is minimal since the terrain is mostly open scrub and mangrove edge, so exposure to sun and wind is significant for the full loop. Along the way, an observation platform overlooks Laguna Ciega, known for resident American crocodiles, and the trail passes a small Maya lighthouse ruin before reaching the Celarain lighthouse tower, which visitors can climb for panoramic Caribbean views. There are no natural water sources on the trail, though the visitor center near the entrance sells drinks and snacks. The lighthouse and the adjacent Colombia Lagoon snorkeling area serve as a natural end point and turn-around for the loop, after which many visitors continue on to the reserve's beach club.
