Dry season runs from July to November, with temperatures ranging from 20ºC to 26ºC. Things get wetter and more humid between December and June, with temperatures reaching 35ºC.
Two airports serve the islands: Isla de San Cristóbal, south of Santa Cruz, and Isla Baltra, just off its northern coast. There are daily flights to both from Quito and Guayaquil on Ecuador's mainland, where flights from the US and Europe will land.
Boats
If you're heading from Baltra airport, you'll need to take a short boat ride over the Itabaca Channel to get to Santa Cruz.
Automobiles
No car needed. Hotels and camps on the islands tend to provide airport transfers and organised day-trips are plentiful.
