First time in San Pedro de Atacama? Everything you need to know before traveling
If it's you first time in San Pedro de AtacamaYou're going to need more than a list of tours or a tourist map. Because this place doesn't work like others. You don't walk through it, you walk through it. And if you don't have certain details in mind—about the weather, the altitude, the actual weather, and even the energy of the place—you can miss out on more than you imagine. And I don't just mean missing a tour.
When I arrived, I had too many expectations and too little useful information. I didn't know what the cold felt like at six in the morning or how tiring it could be to walk at altitude. I also didn't imagine that a sunrise could suddenly make you cry. That's why this guide exists: to accompany you on your first trip to San Pedro de Atacama without frills or empty promises. Only what you really need to enjoy it.
Why choose San Pedro de Atacama as your first destination in the north?
There are many incredible places in northern Chile, but few can leave as deep an impression as San Pedro de Atacama. For someone traveling to this part of the country for the first time, this small town in the middle of the desert is not only an excellent entry point, it's a complete experience. You don't need to know much or have complex logistics to enjoy it. You can easily get there from Calama by transfer, explore the town on foot, book excursions without any complications, and, above all, feel like you're in a place unlike anything you've ever known.
San Pedro de Atacama combines the essentials: extreme nature, living history, and an environment that, despite its ruggedness, is hospitable. There are no large buildings, no shopping malls, no urban noise. Just adobe houses, dirt roads, skies that seem from another planet, and a silence that is disconcerting at first… and later appreciated. This makes it perfect for a first trip to the north: because it does not require previous experience, but it does leave a mark.
It's also one of the few destinations where you can experience the power of the landscape without having to exert yourself physically. There are excursions for all levels, accommodations for all budgets, and activities that can truly change your life: stargazing in the driest desert in the world, floating in a salt lake, watching a sunrise among active geysers... all in one place. Therefore, start with San Pedro from Atacama It's more than a good decision: it's a way to start off on the right foot.
What weather to expect (and how to adapt to the altitude)
One of the most important things to keep in mind before traveling to San Pedro de Atacama is its extreme climate and altitude. Although the photos show blue skies and luminous landscapes, your body can face conditions unlike anything you'd find in everyday life. During the day, especially in summer, temperatures can exceed 25°C, but at night they drop sharply, even reaching below zero in some seasons. This temperature range requires you to prepare your suitcase and your mind well.
Furthermore, the town is located at more than 2,400 meters above sea level. You can already feel that. Walking a few blocks can be more tiring than usual. But what really requires adaptation are some excursions that exceed 4,000 meters, such as the Tatio Geysers or the Altiplanic Lagoons. For those who have never been at altitude, the effects can range from a mild headache to dizziness and intense fatigue.
The best recommendation is to arrive at least one day before engaging in demanding activities. That acclimatization time can make a big difference. It's also essential Stay hydrated constantly, avoid alcohol in the first few days and avoid any sudden physical exertion as soon as you arrive. The body needs time to understand its surroundings, and in the desert, that learning takes effect.
In short, San Pedro de Atacama is unforgiving to those who underestimate it. But if you travel with respect for the climate and altitude, the rewards are abundant: landscapes that seem from another planet and a connection with nature that is difficult to explain in words. You just have to know how to prepare to receive them.
What clothes to wear (and what to leave at home)
Packing for San Pedro de Atacama isn't the same as packing for a regular trip. Here, the weather changes drastically between day and night, the sun burns even if you don't feel it, and the dirt gets into everything. Clothing not only has to be comfortable, it also has to work for the desert. It's not about dressing for an extreme adventure, but it is about being smart. Packing the right things can help you enjoy your trip without any unnecessary discomfort or surprises.
Layered clothing (key to surviving temperature swings)
It can be hot during the day, but when the sun goes down, the temperature drops significantly. The best strategy is to dress in layers: a breathable t-shirt as a base, a warm mid-layer (fleece), and a windproof or waterproof jacket on top. This way, you can adjust according to the time of day without having to change completely.
Comfortable and durable pants
Forget skinny jeans or any clothing that restricts your movement. Here you walk a lot, climb trails, and sit on the ground. The ideal pants are trekking or athletic, but they can also be worn out to dinner without looking like you just came down from the hill. If they have secure pockets, even better.
Closed shoes with good grip
You don't need professional boots, but you do need something firmer than urban sneakers. The trails are uneven, with loose soil, rocks, and in some cases, salt or mud. Ideally, closed-toe, dust-resistant shoes with non-slip rubber soles. And please: that are already used, because wearing new shoes in the desert is inviting blisters.
Real coat (not a light sweater)
In the early mornings, especially on excursions like the Tatio Geysers, it's very cold. Not a little cold. Really cold, with gloves and a hat. Therefore, in addition to layered clothing, it is necessary to bring at least a thick coat or parka that can withstand temperatures close to zero.
Hat, sunglasses, and sunscreen
Solar radiation is strong even when you don't feel it. A hat with a visor or a wide-brimmed cap helps protect your head and face, sunglasses protect your eyes, and sunscreen is essential to avoid sunburn. It's also a good idea to bring lip balm with a UV factor.
What to leave at home (really)
Elegant clothes, formal shoes, delicate accessories. All that is superfluous in San Pedro from Atacama. Dust is in the air, on backpacks, on towels, in hair. There's no point in wearing clothes that are easily ruined or require care. Nor is it worth carrying a hairdryer, full makeup, or perfume. In the desert, none of that matters.
How to get around the town and its surroundings
Getting around San Pedro de Atacama is much easier than it seems. The town itself is small, almost everything is walkable, and generally, you don't need your own transportation to enjoy most activities. The short distances, the structure of the town, and the logic of local tourism mean that getting around is not a concern.
The center of San Pedro de Atacama is organized around a few main streets: Caracoles, Toconao, and Gustavo Le Paige. Most of the tour agencies, restaurants, hostels, shops, and services are concentrated there. Walking through the center is easy, safe, and even pleasant. You don't need a GPS or large maps. Just pay attention and go with the flow.
For tours, most agencies include pickup and drop-off on one of the main streets, Caracoles, which is a great advantage. Transfers arrive at the agreed-upon time and return to the same location. This detail facilitates travel logistics and allows you to enjoy each outing more peacefully.
Some people choose to rent bicycles to visit nearby sites like Pukará de Quitor or Death Valley. It's a good option if you have some experience and are in good physical condition, but you should consider the sun, the altitude, and the lack of shade on the trails. It's not ideal for everyone. In these cases, moving on foot or on a tour is still the most practical and safe option.
Some people also consider renting a car. It can be useful if you want to explore beyond the typical destinations or have completely flexible schedules, but it's unnecessary for a first-time visit. The cost is high, the roads aren't always well marked, and many routes require off-road driving experience. Furthermore, parking within the town is limited.

Death Valley, Pukará de Quitor or the Kari viewpoint are accessible by bike or on foot., if you're well-informed and in good physical condition. But for most iconic experiences, tours remain the most practical, efficient, and enriching option.

Practical tips to keep things running smoothly
The experience in San Pedro de Atacama can be extraordinary… or frustrating. It depends, in large part, on how you plan and experience it. It's not about having a perfect itinerary, but rather understand the rhythm of the place, its particularities and some unwritten rules that make the difference between a good trip and a great one. These tips don't come from tourist brochures, but from what actually happens when you're there.
Don't fill the itinerary from day one
The temptation to rush everything is strong. But San Pedro de Atacama doesn't work that way. The body needs to adapt to the altitude and the climate. Booking a demanding tour for the first day can ruin the experience. It's best to allow time for acclimatization, walk aimlessly on the first day, get to know the town, and listen to your body before pushing it.
Hydration is not optional
The air is dry, and the altitude causes fluid loss without realizing it. Drinking water regularly is the best way to avoid headaches, fatigue, and discomfort. Carrying a reusable bottle and drinking even if you're not thirsty can completely change your trip.
Ask everything, even if it seems obvious
In agencies, in hostels, in restaurants. Don't assume everything is included, that the guide will arrive on time, or that the restaurant accepts credit cards. San Pedro de Atacama is a simple place, but it's not necessarily standardized. Confirming the details avoids misunderstandings.
Always carry cash
Although many places accept cards, There are times when the system doesn't work or there are small charges that only accept cash. Having some local currency on hand is useful for paying for tickets, tips, or any unexpected expenses along the way.

Common mistakes when traveling for the first time (and how to avoid them)
San Pedro de Atacama is a unique destination, but it also has pitfalls for those who come without prior experience with extreme climates, altitude, or rural logistics. Avoiding certain common mistakes can make the difference between a trip filled with memorable memories and one filled with avoidable frustrations. Here are some of the most common ones, and how to avoid falling into them.
Booking activities without understanding the correct order
One of the biggest mistakes: taking the Tatio Geysers tour the day after arriving. Your body isn't ready for that altitude. Lack of acclimatization can cause headaches, nausea, and general malaise. It is advisable to start with lower activities and gradually increase.
Wearing inappropriate clothing
Going to the desert doesn't mean constant heat. Many people arrive in summer clothes, sandals, and no coat, believing they'll be in the sun all the time. Wrong. Temperatures drop dramatically and the wind can be very cold. Dressing in layers, wearing a jacket, and remembering a hat and gloves for early morning hikes is essential.
Thinking that everything is close
Some people think they can walk or bike to most tourist attractions. In reality, Many places are more than an hour's drive from the town. Underestimating distances and road conditions leads to frustration or even danger if you set off unprepared.
Blindly relying on word of mouth to choose tours
Although recommendations from other travelers are helpful, They are not always a guarantee of quality or safety. It's best to compare options, check real reviews, and ask about insurance, cancellation policies, and guide certificates before making a decision.
Do not bring snacks or food for the tours
Some excursions are long and the time between meals may be extended. Bringing cereal bars, dried fruit or crackers can save the day, especially on routes that do not have shops or intermediate stops.
Underestimating the importance of sleeping well
With so many activities and early mornings, fatigue can accumulate. Lack of sleep, skipping meals, or not resting between excursions can ruin the rest of the trip. Planning breaks, even if they seem like “wasted time,” is key to enjoying yourself without burning out.
