Best time to visit
Because of its southern hemisphere position, Bolivia’s winter is from May to October, but this is actually the best time to visit. The country is still warm, with no rainfall or intense heat to ruin your holiday. The highlands and mountains will be pretty cold, but still not cold enough to make exploring impossible.
If you want to experience the salt flats with the water surface (no doubt the prettiest!), you should visit in the rainy season from January to March.
