Carwash

Carwash looks like a farm pond and dives like a dream sequence. In the cooler months its water turns glassy and the sun lights a garden of lily stems from below, their pads floating overhead like green parasols — one of the most photographed views in cenote diving. In summer a red-brown tannic layer floats on the surface and tints the light amber, a different mood rather than a flaw. Along one wall the cavern zone opens under a fringe of stalactites for guided passes, and small fish, freshwater turtles, and the site's occasional young crocodile keep the shallows busy.

您此行的高光时刻: Underwater lily garden, amber tannic light in summer, easy cavern mouth, roadside logistics.

地形地貌: An open pond over limestone, with lily pads and reeds at the rim and a decorated cavern mouth below one wall.

入水方式: Roadside pool on the Coba road where taxis were once washed — hence the name; simple steps into open water.

危险因素: Tannic layer can dim the first meters in summer; the cave zone beyond the cavern mouth is for full cave divers only.

许可证与规定: Entrance fee at the gate; cavern passes require a guide.

保育: The lily beds are living structure — stay horizontal and clear of the plants.
