How to cross from Salar de Uyuni to San Pedro de Atacama, Chile?

Honestly, the easiest way to go from Uyuni to San Pedro de Atacama is to arrange a normal 3-day, 2-night 4×4 tour that plainly ends with a border handoff at Hito Cajón.

On the last morning of the 3-day trip, your Bolivian driver leaves you at the high-altitude border post. After you get stamped out of Bolivia, you then hop into an already waiting Chilean minibus, which moves you through the remaining hour down the slope into San Pedro de Atacama. Make sure the tour provider puts that transfer fee in the initial cost, so you don’t end up with surprise charges.
