For those looking to spend more time in the Galápagos, this 17-day itinerary includes visits to several islands and loads of opportunities to observe unique wildlife. From colonies of marine iguanas, to blue-footed boobie nesting sites and the coolest acting giant tortoises in the Western Hemisphere, the Galápagos are so much more than a collection of islands; they're a lesson in evolution itself (and a fun one, at that!).
