Exploring Life's Adaptations on Bolivia's Altiplano: A Journey Through the Salar de Uyuni

Embark on an extraordinary adventure with Explora's La Travesía, a remote road trip linking Chile's Atacama and Bolivia's Salar de Uyuni. This 325-mile journey offers a unique insight into the remarkable adaptations that allow life to thrive in the harsh high-altitude environment of the Altiplano.

The tour begins in the Chilean town of San Pedro de Atacama, known for its clear skies and the conical volcano, Licancabour. As you traverse the Atacama desert, you'll notice the 'roads' are mere suggestions of routes that run through the high desert.

Your first stop on the Bolivian side is near Laguna Blanca, where you can witness the unique blend of colours in Laguna Colorada, caused by a complex mix of minerals. Here, hundreds of James's flamingos and vicuñas can be found, thriving in the extreme conditions.

The vicuñas, once hunted to near extinction, have adapted remarkably to the harsh conditions of the Altiplano. They have developed efficient oxygen transport systems and adapted hemoglobin variants, allowing them to better cope with the low atmospheric oxygen conditions. The Bolivian vicuña population is now estimated to be in the hundreds of thousands.

The journey continues with stops at three new lodges built by Explora along the way. The first lodge on the Bolivian side offers breathtaking views of the vast whiteness of the Salar de Uyuni. The climb to the summit of an island in the middle of the salt flat provides a stunning panorama of the antique ocean that was once there.

The Salar de Uyuni, the final leg of Explora's tour, is an antique ocean drained until a thick salt crust was left above a huge briny sea of lithium. Explora has set up its final lodge just outside the salt flat, on a peninsula with excellent views across the ivory land.

Sunsets on the Salar de Uyuni are an event, with shadows stretching impossibly long and giving the impression of aliens 100ft tall. The final excursion involves hiking up one of the 30 islands in the midst of the ancient sea, offering a unique perspective of the Salar de Uyuni.

Life on the Altiplano has developed unique adaptations to survive its extreme high-altitude environment. These adaptations include microbial adaptations, physiological adaptations in animals and humans, behavioural and ecological strategies, and thermal regulation. Together, these adaptations enable life to persist in the Altiplano’s high-altitude, cold, arid, and UV-intense conditions, demonstrating remarkable evolutionary innovations across different domains of life.
