Isla Incahuasi, located in the Salar de Uyuni, Bolivia, is a rocky island famous for its giant cacti, some of which are hundreds of years old, and stunning panoramic views of the salt flats. Accessibility can be limited depending on the season; the rainy season (December to February) may make access difficult or impossible due to flooding. While it is possible to visit solo, it's generally recommended to go with a guided tour from Uyuni or a nearby town, as transportation across the salt flats requires a 4x4 vehicle and experienced drivers. The typical visit lasts around 1-2 hours, and the cost, including transportation and entrance fees, can vary widely depending on the tour operator and inclusions, but expect to pay around $20-$100 USD. Be sure to bring sunglasses and sunscreen due to the intense glare from the salt flats. The altitude is very high (around 3,656 meters or 12,060 feet), so acclimatization is crucial.
