Araucaria trees and Llaima volcano in Conguillio National Park, Chile

The umbrella-like trees we see here peppering the landscape are formally named Araucaria araucana, but are more commonly—and whimsically—known as monkey puzzle trees. It's Chile's national tree, and a major reason this 150,000-acre national reserve was established in 1950. Along with these now-endangered evergreen trees, Conguillio National Park hosts a variety of wildlife, including some animals you're likely familiar with (pumas), and others you may have never heard of, including kodkods, pudús, chillas, and culpeos. Overlooking everything at Conguillio is Llaima, a massive stratovolcano that's quite active: It erupted as recently as 2009.
