Sótano de las Golondrinas
A giant vertical shaft cave about 376 meters deep. At dawn, thousands of swifts and parrots swirl out of it, a natural wonder of global renown.
The opening of the Sótano de las Golondrinas is about 60 meters across, and its vertical depth is about 376 meters. It is one of the deepest open-air shafts in the world. The most dramatic moment comes shortly after sunrise, when tens of thousands of white-collared swifts and green parakeets spiral up and out of the opening. In the evening, around 5–6 p.m., they swoop back in flocks to roost. The viewing platform sits at the edge of the opening and must be secured with ropes. You have to walk down about 500 steps from the parking lot. Entry is cheap. You need to set out before dawn. The drive from Ciudad Valles takes about 1.5 hours.
Opening hours
About 06:00–18:00
