Overview
Tulum is a rare place where world-class cavern diving meets easy Caribbean reef time. Shore is the staging area for boat rides to the protected Arrecifes de Tulum National Park, while inland limestone sinks open to haloclines, hydrogen sulfide clouds, and sculpted speleothems. Conditions are friendly for new divers on the reef and exceptionally photogenic for experienced divers inside the daylight zones of cenotes. Snorkelers score turtles at nearby Akumal and glassy lagoons in Muyil. Topside, Sian Ka'an Biosphere Reserve delivers wildlife, mangroves, and mirror-flat lagoons. With a new international airport and solid bus links, Tulum works for long weekends or extended training blocks.
Tulum lies on the Mesoamerican Reef with shallow patch reefs off the hotel zone and a vast inland karst network. Cenote water stays near 24°C, while the sea ranges roughly 26°C to 29°C through the year. Trade winds can bring afternoon chop on open water, but cenotes remain calm.
