Is it safe to drink the tap water?

No. Always drink bottled or filtered water, and use it for brushing your teeth too.

Do I need to speak Spanish?

Basic Spanish is extremely helpful. In the cities, you can get by, but in rural areas or on tours, English is rarely spoken.

What is the best way to handle the altitude?

Hydration, limited alcohol intake, and gradual ascent are the only proven methods. Consult a doctor about acetazolamide (Diamox) before your trip.

Planning Your First Trip to Bolivia

Spend at least 12 days to cover the core loop of La Paz, Uyuni, and Sucre. Prioritize acclimation in La Paz for 3 days before heading to higher altitudes to avoid severe altitude sickness.

Allow for Altitude Acclimation. Do not fly into La Paz and immediately book a flight to Uyuni. Stay in La Paz (3,640m) for 3 full days to adjust. Take it slow, drink coca tea, and stay hydrated before heading to higher elevations.
Book the Uyuni Salt Flats Tour in Advance. Book your 3-day salt flat expedition with a reputable company based in Uyuni or La Paz at least 3 weeks before departure. Ensure they have a 4x4 vehicle and oxygen tanks on board.
Use Domestic Flights to Save Time. Bolivian bus travel is cheap but grueling. Use BoA (Boliviana de Aviación) for the 45-minute hop between La Paz and Sucre to avoid a 12-hour bus ride.
Manage Your Cash. Carry physical US Dollars (printed after 2013) to exchange for Bolivianos at local 'casas de cambio'. ATMs in remote areas like Uyuni often run out of cash, so withdraw your budget in La Paz or Santa Cruz.
