Off the western coast of Mexico, about 150 miles west of Guadalajara, lies a pair of uninhabited islands with a very peculiar history.
Formed by volcanic activity thousands of years ago, the islands have never been settled upon by anybody. In the early 1900s, the Mexican government decided to use the islands for military explosives testing, creating a number of extraordinary caves and rock formations on the islands.
Check out some pictures of the islands below:
In the late 1960s, world-famous scientist and environmental activist Jacques Cousteau led an international outcry about the testing, prompting the Mexican government to turn the islands into a national park.
Hunting, fishing and human activity are prohibited on the island, though visitors are allowed to check out the hidden beaches and caves created by the explosions.
The biodiversity of the islands is legendary. Visitors regularly report seeing sea turtles, manta rays, octopus, dolphins, and humpback whales, as well as thousands of species of tropical fish.
The islands are also home to a number of bird species, including the famous Blue-footed Booby, who has quite the scandalous sex life.
