Speckling the vibrant islands of Indonesia is the Ijen volcano complex, a group of 10 stratovolcanoes that have been shaping the region for millennia. Among these cones is Mount Ijen, home to a sparkling turquoise lake and beneath, lava. During the day, visitors to the crater can spot floating bits of neon yellow sulfur, courtesy of its very active piping. At night, it’s another story.
