The decision that shapes the trip
Wet season vs dry season at Salar de Uyuni
The mirror or the hexagons — the single biggest choice you'll make.
Two completely different places
The Salar de Uyuni is really two experiences depending on when you come. In the wet season a film of water turns it into the mirror that made it famous, reflecting the sky so completely that horizon and heavens merge. In the dry season it's a hard, blinding-white plain fractured into endless salt hexagons. Deciding which you want is the first and most important planning step.
The wet-season mirror
From roughly December to April, rain can flood the flat into a giant natural mirror — the setting for those surreal reflection photos. It's the reason many people come. The trade-offs are that rain and cloud are more frequent, the mirror is weather-dependent rather than guaranteed, and flooding can put some areas, islands and longer routes temporarily out of reach.
The dry-season plain
From about May to November the flat dries out into the classic white expanse of salt polygons under deep blue skies. Access is reliable, the islands and salt-processing sites are open, and the full three-day expedition through the lagoons and deserts runs at its best. You lose the mirror, but you gain clear weather, the perspective-trick photos on the hard salt, and dependable logistics.
The shoulder sweet spot
The edges of the wet season — often around late November or the tail end in April — can occasionally offer a little of both: patches of water for reflections alongside accessible dry salt. It's a gamble that depends entirely on the year's rains, but for travellers desperate to hedge, timing a visit to the transition can sometimes pay off.
How to choose
If the mirror photos are your dream and you can accept some weather risk, aim for the heart of the wet season. If you want the three-day expedition, reliable skies and guaranteed access, choose the dry season. There's no wrong answer — but going without knowing which one you're getting is how people end up disappointed at the one place where the season truly changes everything.
