Almost the entire route between Bolivia's dusty town of Uyuni and San Pedro de Atacama, just over the border in Chile, is made up of dirt roads. Drivers often go off-roading through the desert.

Bolivia's southwest altiplano is home to three species of flamingos, James's, Andean and Chilean. The flamingos get their pastel pink color from carotenoids in the crustaceans they eat in the salty water of the lagoons.

There's little wildlife on the trip, though you do see lots of flamingos, the occasional flock of vicunas, lone Andean foxes and llamas decorated with colorful pieces of string near the area's few tiny settlements.

In the middle of the Salar de Uyuni, Isla Incahuasi pops up like something out of a dream. An island of giant cactus, it's the remains of a volcano that was submerged when the area was part of a prehistoric lake.

Salt, sand, sky: A Bolivian 4x4 adventure
CNN  — 

Landlocked Bolivia has much to offer travelers, from the wildlife-rich Amazon rainforest to treks in the Andes mountains.

One of its lesser known highlights, however, is a remarkable 4x4 journey through the altiplano (high plains) in Bolivia’s desert southwest, close to the border with Chile.

Over three days, travelers can take in spectacular and otherworldy desert scenery – terracotta sands strewn with volcanic rocks reminiscent of Salvador Dali paintings, smoking volcanoes, steaming geysers, solidified lava fields and lagoons studded with flamingos.

The jewel is the world’s largest salt flat – Salar de Uyuni.

It’s bewildering and vast – miles of blinding white salt crust stretch in every direction.

[Editor’s note: The original version of this story included a comparison between the size of the Salar de Uyuni and Singapore. Singapore had a 2013 land area of 716.1 square kilometers or 276.5 square miles, according to the Singapore Land Transit Authority; Salar de Uyuni covers an area typically listed at 10,582 square kilometers or 4,086 square miles, though NASA’s Visible Earth catalog lists the size as approximately 8,000 kilometers or 3,100 square miles. The Singapore comparison has been removed.]

Standing atop that crust feels like being on the surface of another planet.

A number of tour operators offer guided 4x4 trips, which typically include transport in Land Cruisers, drivers and accommodation in basic refugios and hotels made out of salt.

Most visitors start the trip from Bolivia’s unlovely, dusty town of Uyuni and end in San Pedro de Atacama, just over the border in Chile.

For smaller crowds and the chance to see the salt flat at dawn, it’s better to start in Chile and end in Bolivia.

Whichever way you do it, it’s an adventurous trip through one of the most unique landscapes in the world.
