How is a 14-day land tour structured?
Answer first: you base yourself in the small towns on the inhabited islands and take a day trip out from each. There is no boat cabin. You unpack in a hotel, sleep in the same bed for several nights, then transfer to the next island and start over.
Three towns do most of the work. Santa Cruz is the center. Puerto Ayora has 12,000-plus residents, the Charles Darwin Research Station and the National Park HQ. Isabela is the largest island, with the quiet town of Puerto Villamil. San Cristóbal is the provincial capital, Puerto Baquerizo Moreno (about 5,400 people), and it has the second airport.
Floreana, home to only about 100-160 residents, is usually a long day trip or a single overnight, not a full base.
You move between islands by inter-island speedboat (a 2-3 hour open-water crossing) or by light aircraft. One thing to keep in mind: on National Park visitor sites you still need a GNPS-certified naturalist guide. Only a handful of spots near the towns, like Tortuga Bay and Las Grietas, can be visited on your own.
