Started in Tulum in 2011 and now the largest of the town's dive shops, with its own desks in Playa del Carmen, Cancún, Puerto Aventuras, Cozumel and — a long way from here — La Paz in Baja California Sur.
The Tulum programme is the full cenote catalogue: Dos Ojos, Chac Mool, Angelita, The Pit. Cavern dives stay within sight of daylight; cave dives beyond that are for cave-certified divers only, and they teach the certification too. Seasonal trips take over the rest of the year — bull sharks off Playa from November to March, whale sharks in June to September, and a night dive with the crocodile at Casa Cenote.
The shop is on Avenida Cobá on the inland side of town, with a café and gear hire on site.
