Tropical Forest Waterfall, Flowing River, Green Ferns

A fall among the ferns

Not far from where the 'thousand waterfalls' of Tumpak Sewu spill down a massive cirque, this single-stream plunge cuts a striking swath through a fern-lined tropical ravine. Fluttering like fluffy fabric, the fall bears the descriptive name Kapas Biru—meaning 'blue cotton' in the local Javanese tongue—after the azure tint its mists often take on. The top of Kapas Biru is about 300 feet above the valley floor, fed by springs that originate even further up on the slopes of Mount Semeru, the tallest peak here on the island of Java.
