How does rainy season affect the Salt Flats Tours?

The Salt Flats (salar de Uyuni) tours leave year round including during the rainy season and in fact many people try to visit during the rainy season in order to see the "mirror effect" of the water sitting atop of the salt flats and reflecting the sky which is an incredible sight. This is caused when the water table below the salt flats has risen enough to cause the water to sit on top of the salt. It is fine to visit the area when there is a certain amount of water but when it becomes too deep (after long sustained periods of rainfall in consectutive days) some places can become inaccesible such as Isla Incahuasi and these must then be omitted from the tours but they can usually continue visiting other parts of the salt flats and the area to the south (the colored lakes, geysers, hot springs etc) are usually not affected so tours are not cancelled completely.

The road between La Paz and Uyuni usually becomes a bit problematic with potholes and other damage caused but the constant rain and is worst in Mar/Apr time. The buses are sometimes cancelled due to this and other forms of transport such as train or flights are recommended or alternatively you can travel via Sucre / Potosi to Uyuni which is a better conditioned road that is less affected.
