More ways to explore the area's outdoor wonders
You step out of the vehicle onto a low, wind-carved plain and the hills ahead look like a painter ran out of restraint — bands of green, ochre, red and pale yellow rise from hard-packed earth. The Domeyko Range here feels deliberate: raw slopes that push the Atacama sky toward the horizon and a silence that lets small sounds — loose gravel, a distant bird — take on weight.

Reserve your spot on the Tour of the Rainbow Valley and Petroglyphs of Yerbas Buenas today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Start early for the best light
Morning or late-afternoon light accentuates the valley’s colors and reduces mid-day heat; book a morning slot if you want softer shadows for photos.
Hydrate and acclimate
Drink water before the tour and carry at least 1–2 L; although altitude is moderate, dehydration and sun exposure are the main discomforts.
Sturdy footwear for scree and shale
Trail sections are uneven with loose gravel — closed-toe hiking shoes with good grip keep you steady on slopes and photographic vantage points.
Leave the petroglyphs untouched
Do not touch, climb, or chalk rock art; follow your guide’s routing to protect fragile engravings and archaeological context.
Sun hat and sunglasses
Crucial for blocking intense Atacama sun during exposed sections.
summer
1–2 L water bottle or hydration bladder
Hydration is the top priority in the high-desert climate.
Sturdy hiking shoes
Provide traction on shale, scree and rocky walkways.
Camera or smartphone with extra battery
The colored strata and petroglyphs reward photography; extra power prevents missed shots.
