Isla Incahuasi, also known as Fish Island, is a small island located in the Salar de Uyuni salt flats in Bolivia. The island is a popular destination for tourists visiting the region and is known for its unique landscape and wildlife.

The island is covered in coral-like rock formations made of fossilized coral and algae, which contrast with the white expanse of the salt flats. Visitors can hike to the top of the island, which provides stunning panoramic views of the surrounding area.

In addition to its geological wonders, Isla Incahuasi is also home to a variety of cacti, including the towering Echinopsis atacamensis, which can reach heights of up to 12 meters (39 feet). The island is also home to a number of bird species, including Andean seagulls and horned coots.

Access to Isla Incahuasi is generally via guided tour from the nearby town of Uyuni, which is located about 50 kilometers (31 miles) to the east. The island can be visited year-round, although the best time to visit is during the dry season (May-October), when the salt flats are most accessible.
