Overview
Mahahual is the low-key launch point for Banco Chinchorro, a vast coral atoll and UNESCO-recognized Biosphere Reserve. Operators here and in nearby Xcalak run weather-dependent day trips across blue water to dramatic walls, spur-and-groove reefs, and shallow wrecks. On the coast, Mahahual's barrier reef offers calm dives and easy snorkels. Rules in Chinchorro are strict, conservation-focused, and enforced by rangers. Summer generally brings calmer seas for the crossing; winter 'nortes' can close the port. Expect warm water year-round, reef-safe practices, and a nature-first vibe rather than resort bustle.

Chinchorro is monitored as free of white syndrome; coral communities remain robust.

Mahahual accesses both Banco Chinchorro Biosphere Reserve and Xcalak National Park.
