The Experience

A low sun slashes across an unimaginable white — the Salar de Uyuni seems to push the horizon away as you stand on salt that stretches over 10,000 square kilometers.

Before You Go

Acclimatize before you go

Spend a day or two in La Paz or Uyuni to reduce altitude sickness; carry acetazolamide if prescribed and ascend gradually.

Layer for dramatic temperature swings

Combine a breathable base, insulating mid‑layer and a windproof shell — nights and mornings can be frigid.

Protect against intense sun

High altitude amplifies UV — use SPF 50+, a wide‑brimmed hat and UV sunglasses.

Pack cash and snacks

Remote stretches have limited services; bring snacks, toilet paper and small bills for park entrances and local crafts.

Local Knowledge

Hidden Gems

•Salt 'eyes' and small salt pools near Colchani for quiet reflections at dawn
•Polques hot springs at dusk — soak with flamingos in view if conditions permit

Wildlife

•Andean flamingo
•Vizcacha

Conservation Note

The Altiplano is ecologically fragile — stay on designated tracks, avoid disturbing flamingo breeding areas and pack out all waste; park fees support Eduardo Abaroa Reserve protection.

Railways and mining shaped Uyuni; steam locomotives and salt trade drove 19th–20th century development and are visible at the Train Cemetery and Colchani salt works.

Common Questions

When is the mirror effect on the Salar visible?

The mirror effect occurs in the rainy season (roughly December–March) when a thin film of water covers the salt; roads can be wetter and some areas harder to reach.

Can I end the tour in San Pedro de Atacama (Chile)?

Yes — some itineraries offer the option to continue to San Pedro de Atacama (~13:00 crossing) instead of returning to Uyuni; passport and border procedures apply.

Is this tour suitable for people with heart or back problems?

No — the trip involves high altitude, long drives over rough roads and some walking; it’s not recommended for those with serious cardiovascular or spinal issues.

Are meals and accommodation included?

Yes — the tour usually includes most meals (three lunches, two dinners, two breakfasts) and two nights in basic hostels (salt hostel and Laguna Colorada area); inform operators of dietary needs in advance.
