Atacama Desert Trekking Tours: Top Outdoor Adventures Awaiting You

The Atacama is one of the most unusual hiking destinations in the world. You can walk through landscapes shaped by salt, wind and volcanic activity, from the dramatic formations of Valle de la Luna and Valle de la Muerte to high-altitude lagoons, salt flats and remote Andean valleys. The region also offers an exceptional combination of nature, archaeology and mountain scenery. Guided Atacama Desert trekking tours make it possible to experience both accessible day hikes and more demanding multi-day adventures while learning about the area's landscapes and culture from a local expert.

The Atacama can be visited throughout the year, but April to June is particularly appealing for hiking because temperatures are generally mild and the summer rains have ended. September to November is another good period for walking, with clear skies and comfortable conditions. From December to March, the so-called Altiplanic winter can bring rain and storms at higher elevations, occasionally affecting routes. Winter brings very clear skies but much colder temperatures, especially on high-altitude excursions.

Expect very dry conditions, strong sun and large temperature changes between day and night. San Pedro can be pleasantly warm during the day, while mornings and evenings are much colder. Conditions become more extreme as you gain altitude, particularly on trips to the altiplano and volcanoes. Summer can bring occasional high-altitude storms, while winter mornings at higher elevations can be below freezing. Check the forecast before each hike and be prepared for changing conditions.

Bring lightweight trekking clothes that you can layer, a warm insulating layer for cold mornings and evenings, and a windproof or waterproof outer layer depending on the season. Good hiking shoes, sunglasses, a hat, sunscreen and plenty of water are essential. For high-altitude or winter trips, add warmer layers, gloves and a beanie. Your guide can advise you on any additional equipment needed for a specific itinerary, particularly for longer or more demanding expeditions.

Beginners can start with shorter guided hikes and excursions around places such as Valle de la Luna, Laguna Cejar or the Río Salado area. Intermediate hikers can consider longer treks, including multi-day routes around Río Salado or trekking in the highlands. More experienced trekkers can choose demanding high-altitude adventures and volcano expeditions, depending on their fitness, experience and acclimatization. Explore-Share offers programs with different difficulty levels, so you can choose an Atacama trek that matches your experience.

The main areas to explore include the Cordillera de la Sal around San Pedro, the Valle de la Luna and Valle de la Muerte, the Salar de Atacama and surrounding lagoons, the high-altitude landscapes around Machuca and Río Salado, and the volcanic terrain of the Andes. Each area offers a different experience, from shorter scenic walks to demanding high-altitude trekking. A local guide can help you combine several areas according to your interests and experience.

Acclimatization is important because San Pedro de Atacama is already around 2,400 meters above sea level, while many Atacama Desert trips reach 4,000 meters or higher. If you are coming from a low altitude, allow time to adjust before attempting the highest excursions. It is sensible to start with lower-altitude activities and progress gradually to higher routes. Stay well hydrated, avoid overexertion during your first days and tell your guide if you feel unwell. Your itinerary should take your experience and acclimatization into account.

Most travelers fly to Calama's El Loa Airport, which is about an hour from San Pedro de Atacama by road. San Pedro is the main base for exploring the surrounding desert, but many hiking areas are remote and require transportation. Depending on your itinerary, your guided tour may include transfers to trailheads and attractions. Guided transportation is particularly useful for longer Atacama Desert trips that reach the altiplano or more remote valleys.

Some short and well-known trails can be accessible independently, but a guide is highly recommended for remote routes, high-altitude hikes and multi-day trekking. The combination of intense sun, limited water, difficult navigation, remote terrain, altitude and rapidly changing conditions can make mistakes more serious. A local guide also knows the terrain, access conditions and how to adapt an itinerary when weather or altitude becomes a concern. For demanding Atacama Desert tours and expeditions, guided travel offers an important additional level of safety.

San Pedro de Atacama is the most convenient base for most hiking and trekking adventures in the area. The town provides access to a wide range of desert attractions and is the starting point for many guided excursions. Staying there also makes it easier to organize several activities while gradually adapting to the altitude before heading to higher areas. For multi-day expeditions, your guide will let you know whether additional overnight stays are required as part of the itinerary.

Explore-Share only promotes trips led by certified guides. The exact certification depends on the guide and itinerary, but the current Atacama selection includes guides with national and internationally recognized qualifications. When choosing your trip, check the guide's profile and certifications to make sure their experience matches the difficulty and altitude of your adventure.

There is plenty to do beyond trekking. You can visit the El Tatio geysers, explore the salt flats and high-altitude lagoons, relax at the Puritama hot springs, discover archaeological sites around San Pedro and visit Valle de la Luna at sunset. The region is also famous for its exceptionally clear night skies, making stargazing and astronomy experiences a natural addition to an Atacama Desert trip.
