Trip Essentials for Antofagasta
Gas & Juice: Critical Pit Stops
Don't get stranded. These are your essential fuel and supply points.
Calama Service Plaza

Insider Driving Tips
San Pedro de Atacama sits at 2,400 meters, and several highlights (like El Tatio) reach over 4,300 meters; spend at least two days acclimating in the town, drink plenty of water, and avoid alcohol to prevent altitude sickness (Soroche).
The desert has an extreme diurnal temperature range; summer days can reach a hot 32°C under intense sun, while high-altitude nights can drop rapidly below freezing (-5°C). Always pack thermal layers!
Visit the Valle de la Luna strictly in the late afternoon; the viewing platforms offer a spectacular, crowd-free panoramic shot of the jagged salt valleys turning brilliant shades of orange and purple in the sunset.
Bring high-factor, reef-safe biodegradable sunscreen and polarized sunglasses; the sun glare reflecting off the white salt flats is blindingly intense.
The Journey: Stop-by-Stop
Valle de la Luna
Baltinache
“An outstanding, reservation-only restaurant in San Pedro serving spectacular, seasonally-curated local indigenous Atacameño fusion dishes (like llama steaks and rica-rica herb ice cream).”
The Great Dune Ridge
Capture the iconic, wide-angle shot of the massive sand dune ridge silhouetted against the pink sunset sky, with the snow-capped Licancabur Volcano looming in the background.
The Salt Caves (Cuevas de Sal)
A narrow, dark slot canyon located near the valley entrance where you can squeeze through tight stone passageways to inspect natural, glistening rock-salt crystals growing inside the cave walls.
Valle de la Luna Reserve
Natural Landmark

Las Delicias de Atacama
“A small, cozy local village cafe in nearby Machuca serving outstanding, fresh local empanadas stuffed with cheese and llama meat, and hot tea.”
Geyser steam columns
Capture the vertical shot of the morning sunbeams cutting through the massive, glowing columns of white steam rising from the boiling volcanic pools.
The Thermal Bath Pool
A large, shallow thermal pool located at the field edge where you can soak in warm, mineral-rich volcanic water (approx 35°C) while watching the steam rise in the freezing mountain air.
El Tatio Geysers field
Geothermal Landmark
“The world's highest active geyser field, featuring over 80 active boiling pools and towering morning steam columns.”
