Among the Giant Cacti

This 3.8 km (2.4 miles) hike is staged in the dramatic Vilama River Canyon, also known as Cactus Canyon or Cactus Valley. This volcanic canyon is carved by the junction of the Puritama River — which means "hot water" in the Kunza language — and the "cold water" Puripica River. This unique mix creates an oasis that supports the highest concentration of the giant, tree-like cactus species, Echinopsis Atacamensis (Cardón). After a 35-minute drive from San Pedro, the circuit usually takes between 2.5 to 3 hours. Although you'll maintain a leisurely pace, this trek has a "moderate difficulty" rating, and requires physical stability and hiking experience. The terrain is uneven at times and requires the occasional use of hands to navigate rocky boulders. The route involves several river crossings (summer rain sees the maximum water level reach knee-height) and high elevation/temperatures. These components foster an immersive hiking experience with high potential for spotting local birds.

Cactus Valley is a living ecosystem where giant cacti have thrived for centuries. Those passionate about natural history will feel in their element here—particularly as your guide is an expert on the Atacama Desert's geology, flora, and fauna. While steering you through this surreal environment, Valeria will share her knowledge of the different formations and how the confluence of the "hot" and "cold" rivers created a one-of-a-kind ecosystem. She will point out native bird species feeding on the desert flora and bathing in the water. Sightings may include the greenish-yellow finch, the variable hawk, mountain parakeets, and the black-billed shrike tyrant. Hiking in the Atacama Desert comes with challenges relating to the arid atmosphere and high elevation. Although rated "moderate", this hike proves far more engaging than the average sightseeing tour. Valeria will ensure you feel safe at all times and urge you to cultivate a mindful experience with the flora, fauna, and terrain.
