Baltra is a flat, arid island in the Galápagos archipelago, in Ecuador. It is home to one of the two international airports in the archipelago and serves as the main entry point for the majority of visitors. A former American military base during World War II, it today offers a raw glimpse of the Galápagos' volcanic landscape, with remarkable wildlife accessible upon arrival.

What to see

Baltra's landscape is dominated by xerophytic vegetation: candelabra cacti, thorny shrubs and black volcanic rocks. Marine iguanas bask on piers and around the airport. Sea lions occupy the ferry pontoons. Frigatebirds and brown pelicans fly over the Itabaca Channel, which separates Baltra from Santa Cruz.

History and context

During World War II, the United States established an air base on Baltra to monitor the Panama Canal. After the conflict ended, the infrastructure was transferred to Ecuador. The island is today jointly managed by the Ecuadorian Navy and the Galápagos National Park. It is also known for a successful land iguana reintroduction program, a species that had disappeared from the island.

Highlights of the visit

The Itabaca Channel

The ferry crossing this stretch of sea between Baltra and Santa Cruz often provides the opportunity to observe sea lions and seabirds up close. The crossing takes just a few minutes and is itself a first encounter with Galápagos wildlife.

Marine and land iguanas

Right outside the airport, marine iguanas are visible on the rocks. The land iguana reintroduction program, conducted with the Charles Darwin Foundation, has allowed this species to recolonize the island after decades of absence.

Seymour Ecological Airport

Baltra's airport was renovated according to strict environmental criteria: solar and wind energy, waste management, local materials. It is presented as one of the world's most sustainable airports.

Photography tips

Morning light, with the arrival of the first flights, is ideal for photographing marine iguanas on dark rocks. The Itabaca Channel offers beautiful views of Santa Cruz's hills in the background. Stay at the mandatory distance from wildlife (two meters minimum required by the park).

Location and access

Baltra is located north of Santa Cruz Island, from which it is separated by the Itabaca Channel. Seymour Airport (IATA code: GPS) receives flights from Quito (UIO) and Guayaquil (GYE). A free bus connects the airport to the ferry dock on the Baltra side. On the other side of the channel, buses and shared taxis serve Puerto Ayora, the main city on Santa Cruz.
