Sima de las cotorras, Natural sinkhole in Ocozocoautla de Espinosa, Mexico.
Sima de las cotorras is a natural sinkhole featuring a circular opening about 160 meters across and plunging roughly 140 meters into the earth. Towering limestone walls surround the shaft, with lush tropical plants covering the surrounding landscape.
Archaeological evidence near the sinkhole reveals human presence dating back some 7,500 years, including red ochre hand prints and ceramic fragments. These discoveries suggest the site held significance for ancient peoples living in the region.
The sinkhole shelters hundreds of Mexican green parakeets that nest in the cliff faces and can be observed year-round. Local guides often point out these birds as the site's most recognizable living residents.
Visiting requires participation in organized tours from the nearby town, as the depth and steep walls demand proper preparation. Wear sturdy shoes and bring sun protection, as conditions vary greatly depending on the season.
Ancient cave paintings decorate the cliff faces and can be spotted through binoculars from designated viewing areas around the rim. The surrounding El Ocote Biosphere Reserve protects this geological wonder along with multiple rock art sites hidden within its boundaries.
