Santa Rosa Wall — Cozumel

Planning a trip?

Hotels, dive operators, gear, and how to get here are on the Cozumel location page.

Overview

Sheer vertical wall plunging from 20 m into the abyss, cut with swim-throughs, tunnels, and overhangs draped in sponges and black coral. The current rides divers along the wall face while groupers, turtles, and the occasional reef shark patrol the blue. Considered one of the finest wall dives in the Caribbean.

Sources & methodology

How we summarise this

We aggregate confirmed occurrence records from GBIF and OBIS within a fixed radius of each dive site. Occurrence records confirm presence and reveal seasonality clustering, but they DO NOT measure per-dive probability — there is no eligible-effort denominator. We deliberately do not publish a numeric '% chance of sighting' from this data.
