Drive east out of San Miguel on the Carretera Transversal and for twenty-five minutes you see nothing but low jungle, a turning for the San Gervasio ruins, and the occasional iguana making a poor decision. Then the scrub stops, the light changes, and the road ends in a T-junction against open Caribbean. Mezcalitos is the palapa sitting in that junction. Almost everyone who circles the island — every jeep rental, every east-coast tour, every scooter that made it — stops here, because it is the first place with cold drinks and a roof in forty minutes of driving.
Start with the thing the view will not tell you. This is the windward side. The Mesoamerican reef that makes Cozumel famous runs down the other coast, so there is nothing offshore here to knock the swell down before it lands. The beach shelves steeply, the shore break drops hard onto coarse sand, and the undertow pulls. There are no lifeguards anywhere on the east coast of Cozumel, and there is no realistic rescue if you get into trouble. People wade to their knees on a calm day and that is the correct ambition.
What Mezcalitos is actually for is lunch and the wind. The kitchen runs the standard windward-coast menu — whole fried fish, ceviche, guacamole made in front of you, tacos, michelada served in a glass rimmed with chilli salt. Tables sit under palm thatch open on three sides, there are hammocks strung in the sand, and a set of speakers that is either the point or the problem depending on your mood. Pay in pesos. Dollars are accepted here as everywhere and the rate applied is not a favour.
The junction location does one more useful thing: it splits the island loop cleanly in half. Turn north out of the car park and the pavement gives out within a few kilometres — the whole northeast quarter of Cozumel is roadless, and the sand track to the Punta Molas lighthouse is a serious four-wheel-drive expedition rather than a detour, explicitly excluded by most rental agreements. Turn south and the Carretera Perimetral runs the length of the wild coast past Punta Morena, Coconuts and Playa Bonita to the Punta Sur gate. Standing in the car park with a beer, you are choosing which half of the island you have time for.
