Overview & Location
The Sótano de las Huahuas is a vast pit formed by the dramatic collapse of limestone—an awe-inspiring result of geological processes over millennia. It is located in the municipality of Aquismón, in the Barrio de San Isidro Tampaxal, about 19 km (half an hour’s drive) from Aquismón and 37 km (an hour’s drive) from the more famous ‘Pueblo Mágico’ of Xilitla. The area surrounding the cave spans approximately 409 hectares and is designated as a Natural Protected Area since 2001—preserving its ecological and cultural value for future generations.

- Proximity: 19 km from Aquismón town
- Access: By car via Carr. 85 Matlapa – Ciudad Valles, with a detour to San Isidro Tampaxal
Main Geological Features
The cave’s immense proportions inspire awe in visitors and scientists alike:
- Depth: 478 meters (divided into two “shots”—202 m and 276 m)
- Diameter: Measures between 60 and 80 meters across

Cultural Significance & Discovery
Sótano de las Huahuas holds profound meaning locally—not only as a natural wonder but also as a ceremonial space for the indigenous Tének community. The name ‘Huahuas’ derives from the Tének word for ‘parakeet’ or ‘parrot,’ reflecting the birdlife that thrives in these depths. Historically, the cave’s existence was documented in 1967 by Dr. Federico Bonet, a noted geologist and exile, but the first technical explorations were conducted by American speleologists led by Sid West, under the Association for Mexican Cave Studies.

Wildlife Spectacle: Birdwatching & Avian Phenomena
The real magic at Sótano de las Huahuas is not only in its rock formations, but also in its lively aerial ballet. At dawn and dusk, the sky above the pit comes alive with spiraling flocks of white-collared swifts (Streptoprocne zonaris) and green parakeets (Psittacara holochlorus). This daily migration in and out of the cave draws nature enthusiasts and avid birdwatchers from around the world.
- White-collared Swift: Often mistaken for swallows, these birds fill the air with their dynamic movements and songs.
- Green Parakeet: Returning home at sunset, thousands of these birds create a near-deafening yet mesmerizing rush.
