Drive out of San Pedro for a half-day discovery of Rainbow Valley’s geologic colours and Yerbas Buenas petroglyphs. This small-group tour blends short walks, interpretive history and desert geology at about 3,500 m.a.s.l.
More ways to explore the area's outdoor wonders
You roll out of San Pedro de Atacama before the heat and into a landscape that seems to be painted in layers: ochre, rust and pale yellow hills catching the low sun. The vehicle hums westward for about an hour, the Domeyko Range on your left and the Andes farther on the horizon; winds push at the windows like a reminder that this is a living desert.

Wildlife
History
The Valle del Arcoiris area records millions of years of tectonic uplift; Yerbas Buenas preserves rock art left by Atacamenian peoples who moved caravans through these corridors.
Conservation
Stay on designated tracks and avoid touching petroglyphs; the fragile salts and sparse vegetation recover slowly from trampling—pack out all waste.

Acclimatize before you go
Spend a day in San Pedro at moderate activity levels to reduce altitude symptoms—3,500 m can affect even fit travelers.
Sun protection is non-negotiable
High altitude and reflective salt mean strong UV—bring broad-spectrum sunscreen, hat and sunglasses.
Wear closed trekking shoes
Trails are rocky and uneven around petroglyph panels and viewpoints; sturdy shoes improve stability.
Carry water and snacks
The tour includes a breakfast but bring 1–2 L of water and compact snacks to stay energized on walks.
Closed trekking shoes
Provides traction and ankle support on rocky, uneven trails.
1–2 L water bottle or hydration pack
High-altitude sun and dry air increase dehydration risk—carry more than you think.
Layered jacket and windbreaker
Temperatures swing widely; windproof layers keep you comfortable during stops and drives.
Sun hat and UV sunglasses
Protects eyes and face from intense high-altitude sun and reflected light from salts.
