Below are my notes for visiting Bolivia. These travel tips for visiting Bolivia are obtained from a variety of sources including some of the following: my first hand observations, personal conversations, magazines, newspapers, websites, books and so forth.
Best Time to Visit Bolivia
Short Answer: Mid-March to June, Mid-September to Early-November
Longer Answer: Bolivia’s rainy season runs from November to March, with the worst of it being in the middle. The rain brings green vegetation and flowers, but also poor visibility, transportation blockages/delays and mosquitoes. A fair number of festivals and holidays are in this time period, and some of those dramatic Salar de Uyuni salt flat photographs are shot during this timeframe, but the weather makes things less than optimal.
From March into June, the rain is gone and the temperatures are starting to cool going into the austral winter. This is a great time to visit Bolivia. If you are at the Salar de Uyuni salt flats in March, you have some chance of getting rain (which is a good thing).
The high season runs from June through August, with August being the peak month. As a note, Bolivia experiences pretty cold nights at this time of year depending on your location. Rainfall is generally at the lowest it will be all year. The downside is rates are up and, as noted, you might be roughing it through cold nights.
The other best time to visit would be the September through November timeframe when temperatures are starting to climb and the skies are clear. As you progress through the September to November months, your chance for rain at the Salar de Uyuni salt flats increases (which is a good thing).
Miscellaneous Travel Tips for Bolivia
US Citizens get hit with a $160USD visa fee (good for ten years). Updated information here. Note that this changes often. Also, if you are flying to Bolivia, your airline might want proof that you have all your documents including photographs (even if the Bolivian officials don’t care which is often the case). You may need to get a yellow fever vaccination. Research this first.
