After arriving at Baltra Airport, a local guide will pick you up. On the way to Puerto Ayora, stop off at a local farm in the highlands, where there are dozens of giant tortoises. Wander around on your own to appreciate these majestic creatures. Then, enjoy lunch before continuing to your destination. In the afternoon, visit the Charles Darwin Research Station. Witness firsthand the work of international scientists who come to the Galapagos to carry out environmental projects. Head to the nearby Fausto Llerena Breeding Center, where giant Galapagos tortoises breed and are cared for. This is the best place on the islands to see different tortoise species and learn about each one.
