Other Highlights of Salar de Uyuni:
Of course, just being in the middle of the salt flats admiring the beauty of the white ground and the blu sky is per se a highlight, but there are also other awesome experiences you can have when visiting Salar de Uyuni:
Train Cemetery:
The Train Cemetery, or Cementerio de Trenes, is a fascinating and eerie attraction located just outside the town of Uyuni, near the Salar de Uyuni in Bolivia. This unusual site is a resting place for old, rusted-out locomotives and train cars, remnants of Bolivia’s once-thriving railway industry.
During the late 19th and early 20th centuries, Uyuni served as a major transportation hub, particularly for trains carrying minerals like silver and tin from the nearby mines. However, with the collapse of the mining industry and the introduction of more modern transportation methods, these trains were left abandoned in the harsh Bolivian desert.
Today, the Train Cemetery has become a playground for photographers, urban explorers, and curious travelers. The rusted skeletons of trains, some with missing wheels and shattered windows, create a surreal and post-apocalyptic atmosphere. Visitors are free to climb on the trains, explore their interiors, and capture hauntingly beautiful photographs of this decaying industrial graveyard.
Stay in a Salt Hotel: In Uyuni, Bolivia, you can find unique accommodations made entirely of salt, offering an extraordinary experience for travelers: Hotel Palacio de Sal, Hotel De Sal Luna Salada and Casa de Sal (which is in the town of Uyuni, versus in the salt flats like the other two).
Every element, from the walls and floors to the ceilings, furniture, and even sculptures, is meticulously crafted from salt! Intriguingly, due to their construction from salt blocks, these hotels require rebuilding every 10 to 15 years. This is because exposure to rain gradually causes the salt structures to disintegrate over time.
Visit isla Inchausi:
Isla Incahuasi, also known as Inkawasi or Isla del Pescado, this unique island is known for its stunning cactus groves and surreal landscape, making it a popular stop for tourists exploring the salt flats. Isla Incahuasi is situated at the heart of the salt flat and offers panoramic views of the vast white expanse surrounding it. Visitors can hike to the top of the island, where they can enjoy breathtaking views of the salt flat and the distant Andes Mountains. The island is also home to numerous giant cacti, some of which are over 1,200 years old, adding to its mystical charm.
Eduardo Avaroa Andean Fauna National Reserve:
Commonly known as Avaroa National Reserve, is a protected natural area where you will pass through if you opt for a 3 day trip from Uyuni to San Pedro de Atacama.
This national reserve is renowned for its diverse and unique landscapes, ranging from high-altitude deserts to volcanoes, geothermal fields, and colorful lagoons. It is one of the most biodiverse regions in Bolivia, home to various species of wildlife, including flamingos, vicuñas, Andean foxes, and more.
One of the notable attractions within the Avaroa National Reserve is the Laguna Colorada, a stunning red-colored lake inhabited by flamingos. The lake’s vibrant hue is caused by sediments and algae, creating a surreal and picturesque sight. Other attractions in the reserve include the Sol de Mañana geothermal area, where visitors can observe fumaroles and hot springs, and the Salvador Dali Desert, known for its surreal rock formations.
