Snorkel with sea lions, soak up the sun with iguanas or marvel at the natural beauty that surrounds you – just a typical day on a Galápagos tour! Situated 965km (600 mi) off the coast of Ecuador, this isolated haven of biodiversity remains nature’s greatest science laboratory, home to a dazzling array of birds, reptiles, fish and mammals that you won’t find anywhere else. With no known predators, the wildlife in the Galápagos exhibit almost no fear of humans. But really, if you got to lay about on the stark lava fields of Rábida or the white-sand beaches of Española Island, you’d be pretty mellow, too.
