Hidden in the lush mountains of San Luis Potosí, the Sótano de las Golondrinas is one of the most spectacular natural formations in the world. This massive open sinkhole drops vertically into the earth and is famous for the daily flight of thousands of birds that spiral in and out of its depths. Visiting the Sótano is a powerful experience—one that combines geology, wildlife, and a sense of scale that is difficult to grasp until you stand at the edge.

The Cascada de Tamul is one of the most iconic natural attractions in Mexico and the dramatic finale of the Río Santa María. Located in the heart of the Huasteca Potosina, this waterfall is the tallest in the state of San Luis Potosí, plunging powerfully into a deep canyon where turquoise waters meet towering limestone walls. It’s a place defined by scale, sound, and raw energy—and an essential stop for anyone exploring the region.

Hidden deep in the jungle of the Huasteca Potosina, the Pozas of Sir Edward James, also known as Las Pozas, are one of the most unique and surreal places in Mexico. Located just outside the town of Xilitla, San Luis Potosí, this extraordinary site blends tropical forest, natural pools, waterfalls, and towering concrete sculptures into a dreamlike landscape unlike anywhere else.

Created by the British poet and patron of the Surrealist movement Sir Edward James, Las Pozas feels less like a garden and more like stepping into an unfinished dream.

The Río Santa María is one of the most powerful and beautiful rivers in central Mexico. From its birth in the mountains of San Luis Potosí to the point where its name disappears at the Cascada de Tamul in the Huasteca Potosina, the river carves deep canyons, feeds remote communities, and creates some of the most challenging and rewarding routes in the Sierra Gorda.

Along its entire course, it would be hard to find someone who knows this river better. Our hikes and canyon routes follow the Río Santa María through its wildest sections, offering experiences that range from challenging day hikes to multi-day expeditions deep in remote canyon country.
