Asik-Asik Falls

Asik-Asik Falls, also known as Curtain Waterfalls, is a waterfall near Alamada in Cotabato, the Philippines, on the slopes of Mount Ragang. It is known for an apparent lack of a river feeding the fall, with water coming out of crevices on a cliff instead. Asik means "sprinkle" in the Hiligaynon language. Much of the falls are surrounded and covered by lush vegetation, such as ferns and moss. It is theorized that the source of the falls is an underground river.
