Boats off Cát Bà Island, Vietnam

Though views like this show how much human activity goes on at Cát Bà Town on Cát Bà Island, most of this incredibly biodiverse haven is still undeveloped. A third of the island, and a portion of the bay, are preserved as Cát Bà National Park. With little more than 110 square miles of land, Cát Bà contains a variety of environments, from mangrove swamps to rocky karst cliffs. These cliffs are home to the island’s rarely seen, and very endangered, primate, the golden-headed langur.
