Daily baselineLong pants, closed-toe shoes, 2 L water

Thermal underwearUseful for anyone sensitive to cold

Layers: the core system

The desert day is warm (20–27°C in sun), but shadows and nights are cold. Build a system: Base: lightweight thermal underwear or a regular t-shirt. Mid: fleece or wool sweater. Shell: windproof jacket (rain is rare, but wind is constant). Carry all three on every tour. On sandboarding ($89) or a warm-afternoon Moon Valley ($60) day, you might shed layers. On El Tatio ($60) pre-dawn, you wear all three plus gloves and a hat.

Hands and head: the El Tatio reality

El Tatio at sunrise ($60) is ~4:30 am pickup, 4,320 m altitude, often ~−10°C or colder. Your face is exposed; your hands are exposed. Gloves (insulated, touchscreen-friendly if you photograph) and a warm wool or fleece hat are mandatory. Balaclava or neck gaiter optional but useful. Do not skimp here. Everyone on that tour is cold; the warm ones are happy.

Sun protection: the underrated necessity

Altitude + desert = intense UV. Sunburn happens fast, even on cloudy days. SPF 50+ sunscreen, reapply every 2 hours. Sun hat (wide brim, not a baseball cap — cover your neck). Sunglasses with UV protection. Lip balm with SPF. Long pants and sleeves are your friend on full-day tours. A light long-sleeve shirt (merino wool or synthetic, not cotton) sheds moisture and protects skin. Most visitors regret not protecting their face; do not be that person.

Baltinache swimming: the practical part

Baltinache ($58) is seven salt lagoons; swimming is possible in designated ones (occasionally suspended; check beforehand). Bring a swimsuit, a lightweight towel, and water shoes (the lagoon floor is rocky). Do not expect a changing room; the operator stops at a sheltered spot. Bring a plastic bag for wet clothes. Salt-water rinse happens in the lagoon; a shower back in San Pedro finishes it. You can swim in the Atacama; it is surreal.

Insider tip

Layers + gloves + hat + sunscreen. Long pants. 2 L water. Swimsuit if you are doing Baltinache. Everything else is optional. Most hotels have laundry; you can rewear items.

Water and hydration: the non-negotiable

The Atacama is dry. Carry at least 2 L per day. Most tours include drinks (Moon Valley sunset platter, El Tatio breakfast), but bring extra. Do not drink tap water in San Pedro; bottled water is everywhere ($1–2). Drink it constantly, especially at altitude.
