How to Combine Atacama and Uyuni in 7 Days

San Pedro de Atacama and the Salar de Uyuni are separated by a border but united by one of South America’s most extraordinary landscapes. Knowing how to combine Atacama and Uyuni allows you to turn two iconic destinations into a single journey: vibrantly colored lagoons, volcanoes, geysers, high-altitude deserts, and the planet’s largest natural mirror during the rainy season.

The best way to do this is to start in Chile and end in Bolivia. This way, the trip gradually gains altitude, logistics are simplified, and each day keeps the sense of wonder at its peak. This isn’t an itinerary to improvise at the last minute: the distances are long, the altitude exceeds 4,000 meters in several sections, and crossing the border requires coordination. With good planning, the reward is enormous.

How to Combine Atacama and Uyuni: The Most Logical Route

Most travelers fly into Calama, Chile, and then travel on to San Pedro de Atacama, at an altitude of about 2,400 meters. It’s a good idea to book at least three nights there before heading to Bolivia. This gives you time to explore Atacama’s major highlights and, above all, to acclimate before reaching the Bolivian altiplano.

From San Pedro, three-day expeditions to Uyuni cross the Hito Cajón border crossing. The route doesn’t lead directly to the salt flat; first, it passes through the Eduardo Avaroa Andean Wildlife National Reserve, a succession of remote landscapes that alone would justify the trip. You’ll typically spend the night in simple shelters or higher-end accommodations, depending on the itinerary you choose, and arrive in Uyuni on the third day.

You can also make the trip in the opposite direction, starting in Uyuni and ending in Atacama. This is a good option for those flying into La Paz or combining the trip with other Bolivian destinations. However, starting in San Pedro is usually more comfortable for acclimatization and offers a wider range of hotels before spending nights on the road.

Recommended 7-Day Itinerary

Seven days allow you to experience both destinations without rushing through the trip. For those with nine or ten days, it’s best to add extra nights in San Pedro or Uyuni and allow for potential schedule adjustments due to weather.

Days 1–3: San Pedro de Atacama and Acclimatization

The first day should be a quiet one. After your transfer from Calama, take the opportunity to walk around town, stay hydrated, and avoid strenuous physical activity. The altitude can take its toll even on travelers accustomed to the mountains.

Over the next two days, a good itinerary includes the Valley of the Moon at sunset, the Altiplanic Lagoons with Piedras Rojas, and the Tatio Geysers at sunrise. The Tatio Geysers require an early start and reach high altitudes, so it’s best to save this for after one or two nights of acclimatization. If you’re looking for a more leisurely experience, swap an excursion for a visit to the Puritama hot springs or some stargazing.

Days 4–6: Journey across the Altiplano to Uyuni

The fourth day begins early with departure from San Pedro and border formalities. Keep your passport handy, check the entry requirements for Bolivia in advance based on your nationality, and confirm what documentation or payments may be necessary. Conditions change, so it’s best to verify this information before traveling.

After entering Bolivia, you’ll pass Laguna Blanca, Laguna Verde, and the area surrounding the Licancabur volcano. The itinerary also typically includes a stop at the Polques hot springs and the Sol de Mañana geysers. It’s an intense day at high altitude, with temperatures that can drop sharply at dawn.

The second day in Bolivia usually takes you past high-Andean lagoons inhabited by flamingos, wind-sculpted rock formations, and vast desert pampas. Laguna Colorada is one of the most memorable highlights due to its reddish hues, caused by sediments and microorganisms.

On the sixth day, you’ll reach the Salar de Uyuni. The experience varies depending on the season: between January and March, a thin layer of water may form, creating the famous mirror effect, although some routes may vary due to rainfall. During the dry season, roughly from May to October, the salt flat reveals its spectacular geometry of salt hexagons and allows for exploring larger areas with greater predictability.

Day 7: Departure from Uyuni or continuation of the route

From Uyuni, you can take flights to La Paz on specific dates or continue by road to Potosí and Sucre. If your budget and schedule allow, adding a night in Uyuni after the expedition gives you time to rest, review photos, and avoid following the high-altitude route with a long transfer.

Prices and Features to Help You Choose Your Trip

The cost of combining both destinations depends mainly on the type of accommodations, group size, included transfers, and whether you choose shared or private service. The following amounts are approximate per person in U.S. dollars and may vary depending on season, availability, hotel category, and included services.

Before comparing prices, check what each package includes. Park entrance fees, meals, tips, domestic flights, beverages, and border fees aren’t always included. On a multi-country itinerary, a lower price may exclude essential elements of the trip.

When to Travel and What to Expect from the Weather

The best time to visit depends on the experience you have in mind. From April through November, clear skies, more stable road conditions, and very cold nights prevail. This is the preferred time for landscape photography, stargazing, and travelers who value more predictable logistics.

From December through March, the Altiplano summer arrives. There’s a higher chance of rain, especially in Uyuni, but also the possibility of seeing the mirror-like effect on the salt flat. This isn’t guaranteed, and conditions may force changes to the daily itinerary. Those traveling during these months should prioritize the experience over a rigid itinerary.

No matter the month, pack in layers. The midday sun can be intense, while at dawn the temperature can drop below freezing. Sunglasses, high-SPF sunscreen, a reusable water bottle, gloves, a hat, and a thermal jacket are essential. It’s also a good idea to bring cash in small denominations for personal expenses in Bolivia.

Tips for a Comfortable and Safe Trip

Altitude is the main factor that affects your trip. Get plenty of rest during your first few nights in San Pedro, drink water regularly, limit your alcohol intake, and avoid overexerting yourself with physical activity during the first few days. If you have a history of heart or respiratory problems or any other relevant medical condition, consult a healthcare professional beforehand.

The quality of the vehicle, the driver’s experience, and the coordination of accommodations make a real difference in the Altiplano. These are remote areas with limited cell service and basic amenities outside the main towns. Choosing a tour operator with a regional presence allows you to coordinate the crossing from Chile to Bolivia, confirm schedules, and have support available if weather conditions require changes.

For travelers who value comfort, a private tour is worth considering. It costs more, but allows you to customize stops, schedules, and the pace of the trip. On the other hand, a shared expedition is an excellent option for those on a moderate budget and for travelers who enjoy sharing the experience with others—provided they are willing to accept less flexible schedules and itineraries.

Frequently Asked Questions About Atacama and Uyuni

Is it possible to travel from San Pedro de Atacama to Uyuni every day?

It depends on the season, the availability of departures, and border or weather conditions. Routes typically run frequently, but it’s advisable to book in advance, especially between June and October and during holidays.

Do I need a visa to enter Bolivia from Chile?

Requirements depend on your nationality. Some travelers can enter without a visa, while others must apply for one or present additional documentation. Always confirm the current requirements before departure and carry copies of your reservations and travel insurance.

Is this trip suitable for families?

Yes, if the children are used to road trips and if the pace is adjusted accordingly. The altitude and long days require a realistic assessment of each family member’s age, health, and tolerance. A private tour usually offers more comfort in these cases.

Can I do the route if I’m traveling with a lot of luggage?

The most practical approach is to bring a small suitcase or backpack for the journey and leave your main luggage in San Pedro, when the itinerary and logistics allow. 4x4 vehicles have limited capacity, and space must be shared among passengers.

Atacama and Uyuni aren’t two separate destinations on a map—they’re a high-altitude journey best experienced at a leisurely pace. Set aside enough days, accept that the weather has the final say, and leave room to stop and take in a landscape unlike any other.
