Laguna Cejar is a stunning turquoise saltwater lagoon located about 20 km south of San Pedro de Atacama in Chile’s Atacama Desert. Known for its high salinity—similar to the Dead Sea—it allows visitors to effortlessly float on its surface while enjoying panoramic views of the surrounding desert and the Andes mountains, including the Licancábur volcano. Travellers can relax in the lagoon, take unique photos of the vibrant blue waters against the stark desert backdrop, and often spot flamingos and other wildlife in nearby salt flats. Most tours include transport, entry fees, and sometimes visits to other nearby lagoons, making it a perfect half-day adventure for nature lovers and photographers.
