Nestled within the heart of Mexico's Sierra Gorda Biosphere Reserve lies a natural wonder that is both awe-inspiring and a sanctuary for biodiversity - El Sootano de Barro. This colossal open-air sinkhole, approximately 1.5 million years old, resembles an inverted cone with a depth of 455 meters, a vertical drop of 410 meters, and a mouth that stretches 420 meters across.

El Sootano de Barro is not just a geological marvel; it is a living, breathing testament to Mexico's natural heritage. The surrounding terrain is rich with mesophilic forest vegetation, providing a habitat for a variety of species, including the endangered green macaws, for whom the sinkhole provides a sanctuary, hosting the largest known population in Mexico.

Access to this breathtaking site is limited and regulated to protect the habitat. The tourist protection measures were organized by local authorities and environmental groups to ensure safety and preserve the natural site. Reaching El Sootano de Barro requires navigating rugged terrain, making it an ideal destination for adventurous travelers seeking a raw and unforgettable experience.

As the sun sets, the green macaws perform a daily ritual of foraging and returning to their nests in the vertical walls of the sinkhole. Visitors can hike to the rim of El Sootano de Barro for panoramic views and camp nearby to witness this spectacle. The sinkhole is also home to other wildlife, such as pumas and collared peccaries, adding to the wild, untamed allure of the site.

El Sootano de Barro is estimated to have a volume of 15 million cubic meters, making it one of the world's largest open-air sinkholes. Its unique ecosystem and the diverse species it harbours make it a must-visit destination for nature enthusiasts and adventurers alike. A trip to El Sootano de Barro offers more than just a sightseeing opportunity; it's an opportunity to immerse oneself in the heart of Mexico's natural beauty and witness the resilience and harmony of life in one of the world's most extraordinary natural formations.
