Laguna Colorada is a high-altitude salt lake located in southern Lípez, Bolivie, renowned for its red-tinted waters that are home to three species of Andean flamingos. Perched at approximately 4,278 meters, in close proximity to the Chilean border, it stands as one of the highlights of the circuit crossing the Salar de Uyuni and the Eduardo Avaroa reserve.

Why visit Laguna Colorada

The site combines three rare elements: a body of water with ever-changing colors (from light brown to deep red depending on light and wind), white mounds of borax rising from the surface, and a horizon dominated by volcanoes with snow-capped peaks. The lagoon covers 60 km² but remains extremely shallow, averaging about 35 cm, which amplifies the interplay of colors and reflections. It is also one of the principal breeding sites for James's flamingo in South America.

History and protected status

Laguna Colorada lies at the heart of the Eduardo Avaroa National Andean Fauna Reserve, established in 1973 to protect the high-altitude ecosystems of southern Lípez and their flamingo populations. The reserve spans approximately 714,000 hectares in the Potosí department and ranks among the most visited protected areas in Bolivie. The site has been designated a wetland of international importance due to its ornithological value and the fragility of its mineral balance.

The lake's red coloration is not a local myth but the result of distinctive chemistry: the mineral-rich waters harbor sediments, algae, and plankton that react to light. Pigments produced by certain microorganisms turn an intense red when the sun is high.

What to see and observe on-site

Flamingos of the Andes

Three species coexist around the lagoon:

• the Andean flamingo, the rarest of the three, recognizable by its yellow legs;
• the Chilean flamingo, more common, with pale pink plumage;
• James's flamingo (parina chica), long believed extinct and rediscovered in the 1950s.

They feed on the crustaceans and plankton abundant in the brackish waters. Colonies are visible throughout the day, though the best observations occur late morning, when light reveals the contrasts.

Other wildlife

The lagoon's surroundings welcome vicuñas and llamas grazing freely, as well as Darwin's rhea (Rhea pennata), a large running bird related to the ostrich, now endangered. The horned coot nests in low vegetation. Migratory birds such as Baird's sandpiper and Wilson's phalarope make stops here during their transcontinental journeys.

Surrounding landscapes

The shores are dotted with small mounds of salt and borax. Beyond the lagoon, the altiplano steppe stretches toward volcanic cones and the mineral plains typical of southern Lípez.

When to visit

The dry season, from May to October, offers the clearest skies and best visibility, though nights are freezing (often below -15 °C in June-July) and the lagoon may partially freeze in winter. The rainy season, from December to March, brings slightly warmer daytime temperatures but more challenging tracks. Flamingos are present year-round; the lake's colors are typically most vivid midday in clear, windy weather.

Practical information

• Altitude: approximately 4,278 m. Acclimatization is essential. Avoid ascending directly from low altitude and plan at least one day in La Paz, Uyuni, or Potosí before the circuit.
• Mountain sickness: headaches, nausea, and fatigue are common. Stay hydrated, eat lightly, avoid alcohol. Coca leaves, brewed as tea or chewed, are commonly used locally.
• Equipment: warm clothing (down jacket, hat, gloves), technical layers, high-index sunglasses, sunscreen, headlamp. Reserve accommodations are rustic and minimally heated.
• Entry fee: access to the Eduardo Avaroa reserve requires a ticket, payable on-site in bolivianos.
• Connectivity: no reliable mobile network, nor continuous electricity in most refuges.

How to get there

Laguna Colorada is visited almost exclusively as part of a 4x4 circuit departing from Uyuni, approximately 350 km to the north. The dirt track, punctuated by elevation changes and river crossings, is not passable in ordinary vehicles or on two-wheelers. Classic tours last three days and two nights: the first day crosses the Salar de Uyuni, the second traverses the lagoons of southern Lípez with an extended stop at Colorada, and the third often includes geysers and Laguna Verde before returning or crossing the border into San Pedro de Atacama, Chile. Departures also exist from Tupiza via a slightly longer reversed itinerary.

Nearby attractions

• Sol de Mañana geysers, at approximately 4,850 m altitude, with fumaroles and boiling mud pools.
• Laguna Verde, at the foot of Licancabur volcano, whose waters turn turquoise in strong wind.
• Polques thermal springs, natural hot springs near Laguna Salada.
• Salar de Uyuni, the world's largest salt flat, crossed at the beginning or end of the circuit.

To extend your exploration of southern Bolivie, you can also visit Hacienda Cayara near Potosí or stop at El Sillar on the Yungas route.
