The best time to visit Bolivia, to explore the entire country is during winter (May to October), with its dry, clear days.
The rainy season is during summer from November to March, which can mean overland transportation becomes difficult. However, April is one of the best times to go to the Salar de Uyuni – the rainy season should have ended, and the days become drier though not too hot. The settled rain on the flat creates a dazzling, reflective view different to most other times of the year.
