Bolivia’s highlands and lowlands have vastly different climates. The most important preparations before traveling are adjusting to the altitude and arranging for cash. The following 10 tips cover high-altitude acclimatization, salt flat seasons, transportation, and safety to help you plan your highland adventure more confidently. There’s no need to rush after arrival—take things slowly, and be sure to confirm your insurance and emergency contacts before departure. This often helps avoid unnecessary complications.

1. Acclimatize to the Altitude First: La Paz and Uyuni are both over 3,500 meters above sea level. After arrival, rest first, avoid strenuous exercise and alcohol, and give your body time to adjust.
2. Manage Altitude Sickness: Don’t push your itinerary too hard. You can drink coca leaf tea and, under a doctor’s guidance, take appropriate medications. If symptoms are severe, descend to a lower altitude or seek medical attention promptly.
3. Choose the Right Salt Flat Season: The mirror-like reflection of the sky is best seen during the rainy season (December to March), while the dry season is ideal for capturing salt flat textures and starry skies—the experiences are completely different.
4. Select a Reputable Tour Operator: The roads and conditions on salt flat and highland routes are complex. Confirm arrangements for accommodation, vehicles, and oxygen support, and avoid hidden fees from budget tour packages.
5. Dress for Warmth and Sun Protection: Day and night temperatures in the highlands vary greatly. Even during the day, bring a down jacket, hat, and gloves, and remember to apply sun protection.
6. Carry Enough Cash: Bolivia is largely a cash-based society, and card payments are difficult in remote areas. Exchange for Bolivian bolivianos in advance in La Paz or Uyuni.
7. Drink Safe Water: Tap water is not safe to drink directly. Purchase bottled water and be cautious with raw street food.
8. Respect Local Customs: When entering communities or religious sites, follow the guidelines, and always ask for permission before taking photos of people.
9. Build in Flexibility: During the rainy season, mountain roads may become impassable and flights may be delayed. Allow extra time in your itinerary for adjustments.
10. Emergency Numbers: Police 110, Ambulance 118, Fire 119. The Bolivian embassy or consulate in your country can provide consular assistance.
