Is it safe to drink the tap water?

No. Drink only bottled water or use a high-quality water purification filter.

Do I need to carry cash?

Yes. Most small shops, markets, and rural tour operators do not accept cards. Carry plenty of bolivianos in small denominations.

Planning a Bolivia Trip: La Paz to the Uyuni Salt Flats

Fly into La Paz to acclimate for at least 3 days before heading to Uyuni. Book a 3-day salt flat tour in advance, then take a flight or overnight bus back to La Paz to avoid backtracking.

Prioritize Altitude Acclimatization. La Paz sits at 3,640 meters. Spend your first 48-72 hours doing light walking only. Drink coca tea and consider asking a doctor for acetazolamide (Diamox) before departure.
Choose Your Uyuni Transport. You have two choices: a 45-minute flight from La Paz to Uyuni, or a 9-10 hour overnight bus. The bus is significantly cheaper but exhausting; the flight saves a full day of travel.
Select a Reliable Salt Flat Tour Operator. Do not book the cheapest tour you find on the street. Research operators online that have a track record of vehicle maintenance, as the 3-day tour crosses extremely rugged, remote terrain.
Book Internal Transit Early. If you are flying, book your BoA (Boliviana de Aviación) tickets 3 weeks out. If taking the bus, buy your tickets at the bus station 24 hours in advance.
