Located in the central part of the Galapagos archipelago, the small, flat island of Baltra (also known as South Seymour island) is the only island that is not part of the Galapagos National Park as it operates as a military base and is home to the local airport. With its extremely arid landscape and its sparse vegetation consisting of little more than prickly pear cacti, salt bushes and palo santo trees, arriving on this remote island can feel like landing on another planet. As the island has been designated as a non-visitor site, travelers who arrive in Baltra will immediately be taken by bus to one of two docks where they will either board a cruise ship or a ferry that will take them to the island of Santa Cruz.
