Salar De Uyuni

During the rainy season (December through March), a thin layer of water covers the Salar de Uyuni and the entire flat becomes a perfect mirror. The sky reflects at your feet; the horizon disappears; the landscape becomes spatially undifferentiated in a way that is nearly hallucinatory. This is why the rainy season is often the better time to visit, despite what the dry-season photography tours claim. The famous perspective tricks and prop photography work in the dry season; the reflection effect doesn’t.

The Salar

At 10,582 square kilometres and 3,656 metres altitude, the Salar de Uyuni is the largest salt flat on earth. The salt crust is between 2 and 10 metres thick, sitting on a brine lake that contains an estimated 50 to 70 percent of the world’s lithium reserves. That geological fact is driving significant international economic attention; the visual fact is that the salar is one of the more specific landscapes available on the planet.

The Tours

The standard format is a 3-day 4WD circuit from Uyuni or from San Pedro de Atacama in Chile (which allows one-way transit and has the advantage of acclimatising you gradually as you ascend from San Pedro’s 2,400 metres).

Day 1 typically covers the salar: Incahuasi Island (Isla del Pescado, covered in giant cacti rising from the salt), sunset on the reflective surface if conditions allow.

Day 2 moves south into the Eduardo Avaroa Andean Fauna National Reserve: Laguna Colorada (a red-algae lake at 4,278 metres inhabited by three flamingo species), the Sol de Mañana geothermal field at 5,000 metres, and Polques hot springs.

Day 3 continues through high-altitude lagoons including Laguna Verde at the foot of Licancabur volcano, then drops to San Pedro or returns to Uyuni.

Tour prices range from USD 40 to 150 per person. The cheaper operators use large shared groups and basic accommodation; the upper end provides smaller vehicles and guides with deeper geological knowledge.

Altitude

Laguna Colorada is at 4,278 metres; Sol de Mañana at 5,000. Cold and altitude are the main challenges. Nights in remote accommodations can drop to minus 20 degrees Celsius in the dry season (June through August). Coca tea is widely available and provides mild relief. Bring a quality sleeping bag.

Practical Notes

Uyuni town is the base: 12 to 14 hours overnight bus from La Paz (around USD 9 to 13), or 1-hour flight via Boliviana de Aviación (from USD 100 one way). Bring BOB 200+ in Bolivian cash for park entry fees (Eduardo Avaroa reserve is BOB 150 per person). US citizens require a Bolivia tourist visa; EU citizens generally do not.

The optimal photography window on the mirror salar is the 30 minutes around sunrise; sleeping on or near the salar the previous night is the only reliable way to achieve this.
