7 days in Chile Atacama Desert (San Pedro de Atacama base) for Adventure – Travel Itinerary

While many main roads are paved or well-graded gravel, a 4x4 or high-clearance SUV is highly recommended. It provides better traction and stability on corrugated dirt roads, deeper sand sections (e.g., some parts near Laguna Cejar), and offers peace of mind when navigating the potentially icy and winding roads to El Tatio Geysers in the dark morning hours. It also allows access to slightly less-traveled spots.

Layers are crucial due to extreme temperature swings. Pack warm clothing (fleece, jacket, hat, gloves) for early mornings/evenings (especially at El Tatio), light breathable clothes for daytime, comfortable walking shoes, sunglasses, a wide-brimmed hat, high SPF sunscreen, lip balm, and a reusable water bottle. Don't forget swimwear for hot springs/lagoons.

San Pedro is at 2,400m (8,000ft), but many excursions go much higher (El Tatio, Altiplanic Lagoons are over 4,000m / 13,000ft). Acclimatize by taking it easy on your first day, staying hydrated, avoiding alcohol and heavy meals initially. Coca tea (mate de coca) or coca leaves (available locally) can help. Descend immediately if symptoms worsen.

Main roads to popular attractions are generally well-marked with signs, but having offline maps (e.g., Google Maps, Maps.me) downloaded is essential as cell signal can be sporadic. Some smaller roads might be less obvious. Always carry a physical map as a backup.

Generally, it is safe to drive alone, but always inform someone of your itinerary. Stick to well-traveled routes, ensure your car is in good condition, and carry enough water, fuel, and emergency supplies (first-aid kit, spare tire, basic tools). Distances between towns can be vast, and services are non-existent in remote areas.
