Incahuasi Island: Discover A Surreal Oasis in the Salar de Uyuni
In the heart of the vast Salar de Uyuni, the largest salt flat on Earth, lies a breathtaking natural wonder: Incahuasi Island. This rocky outcrop, rising dramatically from the endless white salt, is a must-visit destination during the trips through one of the most surreal landscapes in the world. As you approach Incahuasi, the contrast between the endless white salt flats and the rocky island is mesmerizing.
A Hidden Paradise of Giant Cacti
Isla Incahuasi spans an area of 24.62 hectares. The place is the top of the remains of an ancient volcano, which was submerged when the area was part of a giant prehistoric lake, roughly 40,000 years ago. Despite being called an “island,” it’s not surrounded by water anymore, but by a vast expanse of salt.
What makes it truly remarkable is its forest of towering cacti, some reaching over 10 meters in height and are centuries old. These cacti grow only a few centimeters each year and are distinguished by their ability to grow more than twice as tall as other species in their family. Known for their resilience, they thrive in this harsh environment of high-altitude desert (at an elevation of 3,656 meters (11,995 feet)), extreme temperatures, and minimal rainfall.
The cactus species covering the entire Incahuasi Island is Echinopsis atacamensis, commonly known as the giant cardon cactus.
The Incahuasi island is the remnant of an ancient coral reef from a prehistoric lake that dried up millions of years ago, leaving behind fascinating rock formations and fossilized algae.
Unforgettable Panoramic Views
Hiking to the top of Incahuasi rewards visitors with stunning 360-degree views of the salt flat, where the dazzling white landscape meets the deep blue sky. The total trekking until you reach the top is approximately 20 minutes.
During the rainy season, when a thin layer of water covers the Salar, the island appears to float on a massive natural mirror, creating an otherworldly experience.
Common Confusion: Incahuasi vs. Isla Pescado
Many people mistakenly believe that Incahuasi Island and Isla Pescado (Fish Island) are the same place, but they are actually two different islands in the salt flat. Both are home to giant cacti and share a similar volcanic origin, but Incahuasi is the more accessible and frequently visited of the two. Isla del Pescado, located further west and is less visited.
