Car wash cenote also know as Ak Tun Ha, is located about 15 minutes from the shop, on the road to Coba. Carwash is a classic inline sink with both spring and siphon entrances with a very pretty shallow spring basin separating them. A Cavern dive can be made both on the Spring (upstream) and Syphon (downstream) sides but the Spring entrance is by far the larger, more open and more decorated of the two.
