The Salar de Uyuni, located in southwestern Bolivia, is one of the most impressive destinations in the world. With its vast expanse of white salt and surreal landscapes, it attracts thousands of tourists every year. But what makes the Salar de Uyuni special in May? Below, we tell you everything you need to know to plan your visit during this month: what to see, what to do, the advantages and disadvantages, and practical tips to make your experience unforgettable.
Why Visit the Salar de Uyuni in May?
May is a transitional month at the Salar de Uyuni. The rainy season (from December to March) has ended, and the dry season (from May to October) begins to settle in. This means that the famous “mirror effect” of the salt flat, which occurs when a thin layer of water covers the surface, is no longer as prominent. However, May offers other unique advantages, such as clear skies, more pleasant temperatures, and fewer tourists. Additionally, it’s an ideal time to explore the tourist attractions without the complications of extreme weather.

Advantages of Visiting the Salar de Uyuni in May
- Favorable weather: May marks the beginning of the dry season at the Salar de Uyuni. The rains have decreased, making it easier to access the main tourist attractions and improving conditions for tours.
- Fewer tourists: Unlike peak months like July and August, May sees fewer tourists. This means you can enjoy a more peaceful and personalized experience.
- Unique photography: Although the famous “mirror effect” (reflection of the sky on the salt flat) is more common during the rainy season (December to March), in May you can still find small areas with water that allow for stunning photos.
- Moderate temperatures: During the day, temperatures in May are pleasant, ranging from 2°C to 13°C. This makes it more comfortable to explore the salt flat and its surroundings.
- Accessible tourist attractions: Places like Incahuasi Island, the Train Cemetery, and the Salar de Tunupa are at their best for visiting, as the roads are dry and passable.

Disadvantages of Visiting the Salar de Uyuni in May
- Lack of the mirror effect: If your main goal is to see the famous reflection of the sky on the salt flat, May is not the best month. During this time, the water has significantly decreased, and the mirror effect is less visible.
- Cold nights: Although daytime temperatures are pleasant, nights can be very cold, with temperatures dropping below 0°C. It’s important to bring warm clothing.
- Strong winds: May is known for its intense winds, especially in the afternoons. This can make outdoor activities and photography more challenging.
- Less wildlife: During the dry season, flora and fauna at the Salar de Uyuni are less visible. If you’re interested in observing biodiversity, this is not the best time.
- Risk of altitude sickness: The Salar de Uyuni is located at 3,656 meters above sea level, and altitude sickness can affect some visitors. It’s important to take precautions, such as staying hydrated and acclimatizing before engaging in strenuous activities.
