Not for the faint-hearted, this challenging four-hour hike allows experienced walkers the chance to trek to the summit of the impressive volcano, which is located 5000 metres above sea level. The journey on foot begins at roughly 2400 metres and during the ascent hikers are rewarded with spectacular views over neighbouring Bolivia, including the Blanca Lagoon and the vast Salar de Atacama salt flats. We highly recommend acclimatising to the altitude in San Pedro de Atacama for a few days before embarking on this trek.
