The only hard coral reef in the Gulf of California and one of the oldest in the Eastern Pacific, located about 60 kilometres north of San José on the East Cape. The national marine park — a UNESCO World Heritage Site since 1995 — protects a series of granite ridges and coral formations that are home to an extraordinary concentration of marine life.
Diving and snorkelling here are among the best in Mexico: bull sharks, giant grouper, schools of thousands of jacks, manta rays, sea turtles, and whale sharks (in season) are regular encounters. Day trips from San José take about 90 minutes on an unpaved but manageable road; boat trips into the marine park are operated by a handful of small local operators based in the village of Cabo Pulmo itself. Stay overnight in the village if you want early morning dives before the day-trip boats arrive.
