Baltra is a small, flat and dry island in the middle of the Galapagos, best known as the main gateway to the islands and the starting point for many cruises. Unlike most of its volcanic neighbours, it was lifted up from the seabed, and its rocky ground supports only low scrub.
During the Second World War the United States built an air base here to help guard the Panama Canal. Today the island is shared by an Ecuadorian military base and the Galapagos Ecological Airport, built with recycled materials and certified carbon neutral. Land iguanas, which had disappeared from Baltra, were brought back from a neighbouring islet and live here again.
For most visitors it is a short stop between plane and ship, with the beaches, highlands and town of Santa Cruz just across a narrow channel.
