A 3 Day Atacama Desert Itinerary for Solo Travellers (2026)
I arrived in Chile alone as part of my one year round-the-world itinerary and knew I wanted to see Santiago and the street art of Valparaíso. What I didn’t expect from my 2 week Chile itinerary is that I’d end up in the Atacama Desert having some of the most incredible experiences of my whole journey. If you only have a short time in San Pedro de Atacama, like I did, this is what I recommend for a 3 day Atacama Desert itinerary for solo travellers.

The best time to visit San Pedro de Atacama
Peak season runs from December to April. During this time, days are warm and dry and the town is at its busiest with tour groups and backpackers. Outside that window, San Pedro is quieter and cooler. The desert doesn’t really have a wet season worth planning around. I went in November and the weather was ideal.
What the weather is like in the Atacama Desert
San Pedro’s climate is the part most people get wrong before they arrive, mostly because “desert” makes people pack for heat and stop there. The Atacama is one of the driest places on earth, and that dryness matters more than the season you pick.
What catches people out is the swing within a single day, not the difference between months. Daytime temperatures in San Pedro sit comfortably warm, often into the 20s Celsius, with strong, high-altitude sun that burns faster than it feels like it should. The town sits at 2,408 metres, and that altitude strips the air of the insulation that keeps heat in after dark. Once the sun drops, temperatures fall fast and can sit close to freezing, sometimes below it further into the desert. I felt this most on the star-gazing tour, wrapped in every layer I owned and still glad of the alpaca-wool gloves and hat I’d picked up from a souvenir shop earlier that day.
The practical takeaway: whichever month you go, you’re not choosing between a hot trip and a cold one. You’re packing for both on the same day, every day.
What to pack for the Atacama Desert
The temperature swing here is the thing nobody warns you about clearly enough. Daytime in the desert is hot and dry, but once the sun drops the temperature falls fast, and star-gazing tours in particular go out well after dark. Layers are non-negotiable: a base layer, a fleece or warm mid-layer, and a proper jacket for the evening. San Pedro’s souvenir shops sell alpaca-wool gloves and hats cheaply, and I bought mine on arrival rather than packing them, which worked out fine.
For the daytime, you want sun protection over anything else: a hat, proper sunglasses (altitude means stronger UV), and a high-factor sunscreen. Trainers are fine for wandering the town, but if the Valle de la Luna is on your list, pack proper hiking shoes rather than trusting old trainers on loose sand and rock. I didn’t, and I regretted it on the climb.
How to get to San Pedro de Atacama from Santiago
There are two realistic ways in. The bus from Santiago or Valparaíso takes around 24 hours and cost me roughly $100 return, and while that sounds brutal, it’s part of what makes the arrival feel earned. The alternative is an internal flight from Santiago to Calama, around 2 hours, followed by a bus of just over an hour to San Pedro. If you book flights well in advance and travel in low season, fares can drop to as little as $40 return.
Calama has the nearest airport to San Pedro, and flying in is the fastest way to reach the desert if you’re short on time. From Calama airport, transfer buses and shared shuttles run the hour-long final stretch into San Pedro, so budget an extra hour on top of your flight time before you’re properly there.
Where to stay in San Pedro de Atacama
San Pedro is small enough that most of the town is walkable from wherever you’re staying.
Head to Anka Hostel or Hostal Campo Base for a sociable, budget-friendly base. I stayed at Hostal Mamatierra and it was lovely – see the photo below.
If you prefer a hotel, Terrantai Lodge and Hotel Desertica both have a pool – ideal for a dip after a hot day in the desert.
The Hotel Cumbres San Pedro de Atacama is the standout for a proper splurge, thanks to its three pools and spa.

Things to do in San Pedro de Atacama: a 3-day itinerary
Day 1: Go star-gazing under the Atacama night sky
San Pedro’s skies are some of the clearest on the planet, and a star-gazing tour is the one thing I’d tell you not to skip. Wrap up properly, the daytime heat drops fast after dark and I was glad of the alpaca-wool gloves and hat I picked up beforehand.
Our guide used a laser pointer to walk us through constellations before we moved into the observatory. Looking through a telescope with over 180x magnification, a single point of light resolved into a cluster of separate stars, and at one point I watched a shooting star cross the lens. It’s the kind of experience that’s hard to describe to someone who’s never stood under a desert sky like that one.

Day 2: Go sandboarding on the desert dunes
Most tour agencies in town run day trips out to the dunes to go sandboarding. They drive you out in a minivan, fit you with boots and a waxed board, and there’s a guide to give you a short lesson.
I fell a couple of times on my first few runs, but you’re only landing in soft sand. By the end of the afternoon I found a rhythm I was pleased with. My instructor was happy with how I’d picked it up, even if I was never going very fast.

Day 3: Explore the Valle de la Luna
Valle de la Luna, Moon Valley, is named for its resemblance to a lunar landscape: mile-wide craters, an amphitheatre worn from rock over thousands of years, and a stillness that makes the comparison feel earned rather than marketing.
One practical note from experience: I wore my beaten-up old trainers on the trek up, and spent most of the climb slipping on loose sand and parched rock. Proper hiking shoes would have made the whole thing easier. It’s worth the effort regardless. At the summit, we watched the sun go down over the desert with pisco sour in hand while our guide told the mountains’ mythological stories, and it’s one of the days from that whole Chile trip I still think about.

What to add if you have more than 3 days
I only had 3 days in San Pedro and it wasn’t enough. If you have more time in your Atacama itinerary, consider adding these activities.
Take a trip to the 7 hidden lagoons of Baltinache which are salty enough to float in. Laguna Cejar is the other big lagoon spot.
There’s also a tour to the El Tatio geysers, the largest geothermal field in the southern hemisphere, usually paired with a stop at Laguna Chaxa, where flocks of wild flamingos gather. I wish I could have seen this!
Another good day trip from San Pedro is a tour to see the Piedras Rojas, the Red Rocks.
Frequently asked questions about San Pedro de Atacama
Is San Pedro de Atacama safe for solo travellers?
I felt safe in San Pedro. It’s a small town built around one dusty main street, popular with backpackers and tour groups, and I never had a moment of unease walking around after dark.
How many days do you need in San Pedro de Atacama?
Allow 4 to 5 days. I only had 3 and it wasn’t enough. It was long enough for star-gazing, sandboarding and the Valle de la Luna, but I left having heard about the lagoons, El Tatio and Piedras Rojas from other travellers with no days left to see any of them. Keep your first day easy while you get used to the altitude, and the extra 1 to 2 days are for those tours. I’m using them as my excuse to go back.
Is altitude sickness a concern in San Pedro de Atacama?
The town itself sits at 2,408 metres, and some of the tours (particularly El Tatio) go considerably higher. Take it slowly on arrival, hydrate more than feels necessary, and don’t book a strenuous tour for your first day.
Is it better to visit Patagonia or the Atacama Desert?
It depends on the environment you want. The Atacama is for desert scenery, star-gazing and sandboarding, while Patagonia is for glaciers and mountains. Patagonia is a long way south of Santiago, so if you only have a few days, the Atacama is easier to fit in. It is also warmer than Patagonia by day, although desert nights drop close to freezing.
Final thoughts on this Atacama Desert itinerary
I arrived in San Pedro exhausted, ears popping from the altitude, water bottles pressurised in my bag from a 24-hour bus ride. Three days later I left wishing I’d built in more time, and I still think about this part of the trip more than almost anywhere else I went in Chile.
The star-gazing was more amazing than I imagined, while I never imagined I’d try sandboarding down dunes. Watching the sun go down over Valle de la Luna with a pisco sour in hand was the perfect way to end the trip.
There’s a local saying that if you eat mango in the Atacama desert, you’re destined to return one day. I didn’t need to eat any – it’s such a special place, I’m sure I’ll be back anyway.
