The Salar de Uyuni, located in the southwest of Bolivia, in the Potosí department, is the largest salt desert in the world and has several access points that adapt to different routes and travel styles. The most popular is the city of Uyuni, the main operations base, which can be reached by plane from La Paz or by bus and train from Oruro and Potosí, offering a wide range of agencies, hotels, and tourist services. Very close is Colchani, only 20 minutes away, ideal for observing artisanal salt production and purchasing handicrafts, and is also a direct entry point to the salt flats. From San Pedro de Atacama, in Chile, it is possible to access via multi-day tours that cross highland landscapes, volcanoes, and lagoons before reaching the salt flats. La Paz is also a key point, with direct flights and buses to Uyuni, while Oruro and Potosí offer complementary access options such as the Oruro Carnival or the Cerro Rico mines.
Uyuni City (Bolivia) – Main Access: This is the most popular gateway and the main base of operations for tours to the salt flats. You can arrive by Plane: From La Paz there are direct 1-hour flights, Bus: From La Paz, Oruro, or Potosí (8 to 10 hours), and Train: From Oruro, with stops in various towns and nearby attractions such as the Train Cemetery, Archaeological Museum, and local market.
Colchani – Direct Entrance to the Salt Flats: Only 20 minutes from Uyuni, on the edge of the salt flats. You can arrive via tours from Uyuni or private transport. Here you can see artisanal salt production, visit workshops, and browse stores selling crafts made of salt. Many short routes begin here.
San Pedro de Atacama (Chile): Perfect for combining the Salar de Uyuni with the Atacama Desert and its highland lagoons. The tour departs from Santiago de Chile to Calama (by plane) and then by bus to San Pedro (1.5 hours). There are also direct tours to Uyuni lasting 3 or 4 days, crossing the border at Hito Cajón.
La Paz (Bolivia): Connects the capital with Uyuni by air or land. You can go by plane, with a direct flight to Uyuni (1 hour), or by bus, with an overnight journey lasting 10 to 12 hours. The advantage of going through La Paz is the possibility to combine the salt flats with attractions such as Lake Titicaca, the Valley of the Moon, and the Death Road.
Oruro and Potosí: Oruro: Ideal for travelers who want to include Bolivia’s most famous carnival and then continue to the salt flats by train or bus. Potosí: Allows combining the visit with the Cerro Rico mines and then traveling by bus to Uyuni (6–7 hours).

Photography Routes: Usually lasting 1 to 3 days, customized according to the traveler’s interests. This tour focuses on capturing sunrises, sunsets, starry skies, and the mirror effect during the rainy season.
The Uyuni Salt Flat is located in the southwest of Bolivia and is the largest salt desert in the world, with an area of more than 10,500 km² and an altitude of 3,656 meters above sea level. It is located in the department of Potosí and is one of the most impressive tourist destinations in South America due to its unique landscapes and surreal appearance.
This salt flat was formed from the evaporation of ancient prehistoric lakes, leaving behind an immense salt crust that, in some places, can be several meters thick. It also contains one of the largest lithium reserves on the planet.
During the dry season (May to October): the salt flat is completely dry, displaying natural geometric patterns formed by the crystallization of the salt. It is ideal for exploring by 4x4 and visiting islands such as Incahuasi, famous for its giant cacti.
During the rainy season (January to March): a thin layer of water covers the surface, creating the “giant mirror” effect that reflects the sky and produces unique photographic landscapes.
Sunsets at the Uyuni Salt Flat are a natural spectacle for the eyes; both seasons are different but each has something special.
In the dry season (May to October), the horizon seems infinite and the sky is painted with warm shades of orange, red, and purple that contrast with the bright white of the salt. The absence of visual obstacles makes the sunset feel immense, with the light softly reflecting on the crystallized surface.
In the rainy season (January to March), the effect is even more surreal: a thin layer of water transforms the salt flat into a giant mirror that reflects the sky and clouds. During sunset, the reflection doubles the colors, creating the sensation of floating between the sky and the earth. The tones change quickly, and in a matter of minutes, the landscape shifts from golden to pink, then violet, and finally to deep blue before night falls.
In addition, the clean atmosphere and the altitude of the salt flat enhance the sharpness and saturation of the colors, and as the sun sets, the silence of the place reinforces the feeling of being in a completely otherworldly setting.
To enjoy sunsets at the Uyuni Salt Flat comfortably and safely, it is important to bring what is necessary for both the climate and the conditions of the place. Here is a recommended list:
Incahuasi Island: This is one of the most outstanding spots to watch the sunset. Due to its slightly elevated position and the presence of giant cacti, it offers an unmatched panoramic view where the sky and the salt flat seem to merge in a display of warm colors and infinite reflections.
Dakar Monument Area (near Colchani): Another privileged area, close to Colchani, where you can capture unobstructed sunsets. In the rainy season, the salt flat reflects the sky’s tones, creating a stunning landscape, while in the dry season it allows you to enjoy a clear horizon.
Surroundings of Colchani: With a quieter and less crowded atmosphere than Incahuasi Island, this area is perfect for those seeking a serene experience. The reflection of the sky on the salt adds special beauty on rainy days.
Strategic Spots Selected by Local Tours: Many agencies take their groups to off-route observatories, less visited, so you can enjoy the sunset without crowds. These points are usually located in areas with more exclusive access.
The Salar de Uyuni is the world’s largest and highest continuous salt desert, with an area of over 10,000 km². It is located in southwestern Bolivia, in the department of Potosí, at about 3,650 meters above sea level. Formed by the evaporation of ancient lakes, it contains reserves of salt and lithium.
This endless white and flat landscape offers stunning views and unique optical effects, especially during the rainy season (January–March), when it turns into a giant natural mirror reflecting the sky. In the dry season (April–December), the ground is covered with hexagonal patterns of crystallized salt. These are transition months, and while they may feature a combination of landscapes, they don’t guarantee the mirror effect or a fully dry surface. They are ideal if you're looking for fewer tourists and milder weather.
The recommended number of days to visit the Salar de Uyuni depends on the type of experience you are looking for. It's important to wear proper clothing for the cold, as temperatures can drop below 0 °C at night, especially on multi-day tours. It is recommended to dress in layers: a thermal base layer, a warm middle layer, and a waterproof or windbreaker jacket. Don't forget gloves, a scarf, a hat, and sturdy shoes for walking on salt, dirt, and water terrain. Sunglasses are essential due to the intense sun at high altitude and the reflection on the white surface of the salt flat.
The Salar de Uyuni is located at about 3,650 meters above sea level, so some travelers may experience altitude sickness or “soroche.” The most common symptoms are headaches, dizziness, nausea, fatigue, and shortness of breath.
The Salar de Uyuni is located in the Altiplano, in southern Bolivia, in the department of Potosí, in Daniel Campos province, and borders Chile to the west. Uyuni is a Bolivian city from which tours to the salt flat depart.
Visiting the Salar de Uyuni in Bolivia is an enjoyable experience at any time of the year, but the type of landscape you’ll see depends on the season. There are two main seasons that offer different experiences: the rainy season and the dry season.
During the months of January to March, rains turn the surface of the salt flat into a natural mirror. A thin layer of water covers the salt desert, reflecting the sky, clouds, and sunsets with almost surreal perfection. This natural phenomenon is one of the most sought-after by travelers and photographers from around the world.
The downside of visiting during this season is that some areas may become inaccessible due to flooding, some attractions may close like Incahuasi Island, and the terrain can become more slippery and harder to navigate.
During the Andean winter, the salt flat appears as a white, firm desert cracked in natural hexagonal patterns. The weather is dry and the skies are completely clear, allowing for deep exploration of the salt flat in 4x4 vehicles and visits to iconic places like Incahuasi Island, the Salt Hotel, the Train Cemetery, and more.
The advantage of visiting during this season is that you can travel across the entire salt flat without restrictions. Tours reach more destinations in and around the salt flat, and conditions are ideal for excursions, sunrise photography, and stargazing. The disadvantage is that there's no mirror effect, and temperatures can be very low, especially at dawn, sometimes reaching -15 °C.
April and November are transition months, and while they may offer a combination of landscapes, they don’t guarantee either the mirror effect or a completely dry surface. They are ideal if you're looking for fewer tourists and milder weather.
If you're looking for the famous mirror effect and don’t mind missing some locations, visit between January and March. If you prefer deeper exploration, walking on salt, visiting islands, and having clear skies, choose between June and September.
The recommended number of days to visit the Salar de Uyuni depends on the type of experience you are looking for. Here’s a summary based on the most common options:
Traveling to the Salar de Uyuni is generally a safe and accessible experience for tourists. This destination welcomes thousands of visitors each year and has tour operators, guides, and services focused on ensuring a safe and comfortable visit.
One of the most important aspects for a safe experience is to book a tour with a formal agency that has good references. Regarding the climate, it’s important to know that the Salar de Uyuni is over 3,600 meters above sea level. Therefore, it’s common to experience symptoms of altitude sickness, such as headaches or fatigue. The Salar de Uyuni is a safe destination if you take the proper precautions: choose a reliable agency, prepare for the altitude, and follow the guide’s instructions.
Yes, you can rent a 4x4 vehicle in Uyuni and drive to the salt flat, or hire a private taxi. You can also walk to certain nearby points if you just want to see a part of the salt flat (like the edge), but deeper and safer exploration requires more logistics. Keep in mind that the salt flat is a white desert with no clear visual references. It’s very easy to get lost without a guide or specialized GPS, and there are no gas stations, mechanical assistance, or cell coverage in many areas of the salt flat.
That’s why it’s recommended to go with local guides, as they know the safe points, the right timing for crossing, and how to avoid flooded or dangerous areas. If you only want to visit the entrance of the salt flat (e.g., Colchani and surroundings), you can go by public transport or taxi from Uyuni.
It’s important to bring appropriate clothing for the cold, as temperatures can drop below 0 °C at night, especially on multi-day tours. Warm clothing is recommended. Don’t forget gloves, a scarf, a hat, and sturdy shoes for walking on salt, dirt, and water terrain.
Due to the intense sun at high altitude and the reflection on the white salt surface, it is essential to bring sunglasses, sunscreen, and lip balm with UV protection. A reusable water bottle is also useful, as staying hydrated helps prevent altitude sickness.
Cash in local currency (Bolivianos). It’s also recommended to bring energy snacks, toilet paper or wet wipes, personal medications, and if needed, altitude sickness pills.
Bolivia classifies countries into three groups based on visa requirements:
Group 1: No prior visa (exempt)
Group 2: Visa on arrival or at a consulate
Group 3: Mandatory prior visa (only at embassy or consulate)
Yes. The Salar de Uyuni is located at about 3,650 meters above sea level, so some travelers may experience altitude sickness or “soroche.” The most common symptoms are headache, dizziness, nausea, fatigue, and shortness of breath. To prevent it, it is recommended to acclimate in high-altitude cities like La Paz or Uyuni, drink plenty of water, avoid intense physical exertion, and drink coca leaf tea. It’s also helpful to carry altitude sickness pills and travel with an agency that provides oxygen onboard. With these precautions, it’s possible to enjoy the salt flat without complications.
Accommodation during the Salar de Uyuni tour varies depending on the duration and type of service booked. On a one-day tour, there is no overnight stay; the trip departs in the morning from Uyuni and returns in the evening, so visitors usually stay in hotels or hostels in Uyuni town before or after the tour.
In contrast, on 2- or 3-day tours, which are the most popular, travelers spend the night in small villages along the route. The first night is usually spent in places like San Juan, Atulcha, or Colcha K, where many accommodations are built from salt blocks, known as salt hotels. These structures offer simple rooms with basic services that may include shared or private bathrooms, depending on the tour type (basic, standard, or superior).
