Galapagos Islands are famous for their unique wildlife, which was the inspiration source for Darwin. But what will strike you the most are not the differences between the species on each island, but the fearless attitude the animals have. Due to the lack of serious predators the animals will hardly lift an eyebrow when visitors go ashore. You will get really close to iguanas, sea lions, tortoises and birds, though the crabs seem a bit shy. If not careful, you can easily end up stepping on the wildlife. All the islands offer different wildlife experiences, but a visit to islands like Santa Cruz (main island), Espanola, Floreana (both part of the southern loop) and North Seymour (part of the northern loop) will give you a good taste of this truly unique place. Though any visit to the Galapagos Islands will be pricey, it will be totally worth it.
