A local guide is the practical default because the site is reached by boat and conditions can change quickly.
Chunchacah is a southern Cozumel boat dive for divers who want a quieter reef run with real structure. The site is a long coral mound with hard coral heads and sea fans, so the route feels broad and textured rather than steep. Plan on a longer boat ride, current-sensitive diving, and a site that works best when the southern end of the island is settled. It often fits as a second dive after Maracaibo.

Depth range, seasonality, and planning context.
Reported Depth
21m
Depth Note
Reported as a constant 70 ft / 21 m throughout the site.
Best Season
Year-round, but November through May usually gives the cleanest planning window.
Typical Conditions
Long southern boat run, broad coral-mound reef shape, and currents that can shift enough to make a careful drift plan worthwhile.
Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
Treat the site as a current-sensitive reef dive, keep the group tight, and avoid stretching the plan on the longer southern run.
Access Restrictions
Boat access only; use a Cozumel operator familiar with the southern reef run.
Legal Notes
Follow marine-park and operator rules; do not touch or anchor on the reef.
Community notes to help plan your visit.
Scuba Diving
Best as a guided boat dive with steady buoyancy over the coral heads and enough gas reserve for a flexible pickup if the current runs.
Freediving
Not a practical freedive target; the boat profile and current sensitivity suit scuba planning instead.
Snorkeling
Not a practical snorkel site because the reef profile is better suited to scuba and a guided boat setup.
