Calama – Uyuni Bus Tips

We survived the bus from Calama to Uyuni but you can thrive if you follow these 9 tips:

  1. Grab a window seat. Scenery on the journey from Chile to Bolivia is amazing. Particularly on the Chilean side you will see snow capped mountains as the backdrop to sandy filled deserts.
  2. Bolivian Border control don’t check for your yellow fever vaccination. So, if you are wondering whether you need proof of your yellow fever vaccination to enter Bolivia or considering paying $200 for the vaccination to get in – save your cash.
  3. If you are starving by the time you reach the border, the Bolivian side has curries which the locals love. We missed out because we were last through customs.This is so sad, Alexa play Despacito.
  4. No luggage tags. If you like the security blanket of the bus company ticketing each bag and checking it when you want your bag back, you’re out of luck.
  5. The bus is Freezing. You’ve probably read about this elsewhere and it’s 100% true, even in Summer. Locals bring thick alpaca blankets.
  6. Only 2 companies run: Atacama 2000 and Frontera. Both cost 15,000 CLP. A2000 can be booked online at It seems to be more popular and sold out days in advance when we were there. Both buses are located on the same street.
  7. Expect to spend 1-2 hours at customs. It’s pretty boring and slow.
  8. On Frontera, after crossing the border and passing through Chilean customs, the bus pulls over before the Bolivian customs and you change buses with a bus from Uyuni going to Calama. It’s a little chaotic (this is where the bag tags issue is noticeable). After 10 minutes you will board your new bus to Uyuni and proceed to the Bolivian border and customs. On reflection, the waiting time at customs may be to facilitate this bus change over – if the Uyuni to Calama bus is delayed you’ll wait like we did.
  9. See your first Alpaca – how awesome are these guys?!
