Valle de la Luna

Part of the Ischigualasto region featuring lunar-like landscapes with colorful rock formations and eroded badlands. The otherworldly terrain offers an unforgettable visual experience and excellent opportunities for photography and exploration.

Things to do

• Guided Park Tour — Explore the main geological formations with a park-authorized guide who explains the Triassic fossils and colorful mineral-rich rock layers visible throughout the landscape.
• Sunset Photography at Garganta del Diablo — Hike to this dramatic canyon formation where the setting sun illuminates the red and purple rock walls, creating extraordinary lighting for photography.
• Fossil Site Exploration — Visit the paleontological zones where dinosaur remains and ancient plant fossils are visible in the eroded badlands, making this a UNESCO World Heritage Site.
• Hoodoo and Badlands Hiking — Traverse the otherworldly terrain of multicolored rock spires and eroded gullies that resemble a lunar landscape, accessible via marked trails through the park.
• Dawn Visit — Arrive early to experience the landscape in soft morning light when the colorful rock formations appear most vibrant and the park is less crowded.
• Botanical Walk — Discover the hardy desert vegetation adapted to this arid climate, including queñoa trees and native shrubs that have evolved in the harsh Andean foothills environment.

Food to try

• Locro de Chivo — A traditional stewed goat dish cooked with corn, potatoes, and local spices, representing the regional cuisine of San Juan's rural highlands.

Local customs & good to know

• Park Entry Requirements — Visitors must enter with an authorized guide; the park does not permit self-guided exploration to protect the fragile geological and paleontological sites.
• Early Morning Visits — Local guides recommend arriving at sunrise when the colored rocks are most vivid and the desert heat is manageable for outdoor exploration.
• Respect Archaeological Context — Do not touch or remove any rock samples, fossils, or artifacts as the entire valley is a protected UNESCO World Heritage Site with strict preservation laws.
• Desert Safety Customs — Bring plenty of water and sun protection; the high desert environment offers minimal shade and temperatures can be extreme, reflecting how locals navigate this terrain year-round.
