CONANP Closes Four Cozumel Reefs for Two Months to Aid Coral Recovery

Cozumel, Quintana Roo — Four reefs inside Cozumel National Park will be closed to tourism from October 1 through November 30 under the rotating rest program that the National Commission of Protected Natural Areas (CONANP) uses to help coral recover.

The reefs going quiet for the next two months are San Francisco, San Francisco Bajo, Santa Rosa and Pared de Santa Rosa, among the sites most requested by dive operators. Tourist boats will suspend trips to those areas for the duration.

At the same time, five reefs that were closed in August and September — Palancar Cuevas, Palancar Ladrillos, Colombia Somero, Colombia Intermedio and Colombia Profundo — reopened to visitors this week after completing their recovery period.

Blanca Quiroga, who heads CONANP on the island, has said repeatedly that there is no precise way to measure how much an individual reef recovers while visitors are barred, but that its overall condition does improve when access is restricted. That is especially true at the busiest sites, she said, where more fish species have been counted and coral organisms are developing better.

While no exact indicator exists to measure the impact of each individual rest period, the park overall shows positive signs, with greater marine wildlife diversity and steadier balance inside the reef zones — which officials read as evidence of a healthy ecosystem.

Cozumel has used rotating closures since 2019, after White Syndrome was detected in its coral in 2018 and bleaching episodes hit various reef formations a year later. During the pandemic, when tourism shut down entirely, CONANP documented a considerable improvement in reef health, which further justified keeping the program in place.

Tourism operators have largely respected the temporary closures, but authorities still detect unauthorized boats entering the park with tourists despite the restrictions.
