San Cristóbal is one of the geologically oldest islands in the Galapagos archipelago. Its capital, Puerto Baquerizo Moreno, offers a quiet atmosphere where urban life mixes with wildlife; It is common to see sea lions resting on the banks of the boardwalk. The island is home to the archipelago's only permanent freshwater lagoon, El Junco, and features world-class dive sites such as León Dormido. With a mix of coral sand beaches, volcanic trails and unique biodiversity that includes frigatebirds and blue-footed boobies, San Cristobal is a fundamental pillar for scientific and recreational ecotourism in the Pacific.
