During this time, the ground is completely solidified, which allows you to access many places like Incahuasi Island, the highland lagoons, and the geysers found in the surroundings. Additionally, you can cover long distances in 4×4 vehicles without restrictions. It’s the ideal time to enjoy active tourism, walks, bike touring, and excursions through the salt flat islands.
Night photography and stargazing: in the highlands, you can contemplate clear skies with very little light pollution, making it an exceptional place during the dry season.

However, with a bit of luck and the right conditions, the mirror effect can also reflect the stars during the rainy season, creating a doubly magical spectacle.
Tranquility and fewer crowds: the intermediate months (April–May and October–November) are usually the most relaxed, as during these transition periods there’s lower tourist influx. This gives you a quieter atmosphere, with greater accommodation availability and more accessible prices.
The weather during these months is moderate, with pleasant temperatures and the possibility of enjoying both partial mirrors and dry areas of the salt flats.
What to Pack and How to Prepare
Regardless of the best time to visit Uyuni salt flats, preparation is key. Here are some essentials:
Layers of clothing: bring thermal shirts, fleeces, windbreaker or down jackets, gloves, wool hat, and scarf. If you travel during the rainy season, don’t forget to include waterproof clothing, as it’s common to walk over puddles and flooded areas.
Sun protection: the Uyuni Salt Flats are located at over 11,811 feet (3,600 m.a.s.l.), so solar radiation is much more intense, especially due to the reflection of the white salt that amplifies UV rays. Use high SPF sunscreen, sunglasses, and a hat or cap.
Comfortable and waterproof footwear:
- Dry season: opt for comfortable sneakers or trekking boots with good soles for walking on hard and abrasive surfaces.
- Rainy season: Bring waterproof boots. They’re essential to prevent salt water from damaging your shoes and causing discomfort. Remember to clean your footwear well after the tour, as salt can damage it quickly.
Camera: whether you want to capture perfect reflections or play with forced perspectives of the landscape, you won’t want to miss the opportunity to take spectacular visual memories.
- Bring a good quality camera or smartphone.
- A tripod is highly recommended, especially if you’re interested in night or long exposure photography.
Water and snacks: many tours last all day or even several days. It’s essential to bring enough water and some snacks to stay energized and well hydrated during the tour.
