There's a reason Charles Darwin was inspired to ponder the origin of species after exploring the glorious Galapagos Islands. These volcanic islands west of Ecuador are home to an extraordinary number of exotic creatures, including many not found anywhere else.
Visitors commonly spot fur seals, crabs, iguanas, tortoises and birds like the blue-footed booby and Galapagos penguin. Those who snorkel or dive may come face to face with sharks, eels and schools of colorful fish.
Nearly all of the islands have been protected as a national park, and in 1978, they became UNESCO's first World Heritage Site.
These photos of the islands' animals and terrains prove why this destination is a bucket-list must.
