Buniayu Cave

Buniayu Cave is a tourist destination area known for its caves adventure. Located on an area of approximately 10 hectares, Buniayu is located in the village of Kerta Angsana, Sukabumi, West Java, Indonesia.

Name origin

The cave was better known as Cipicung cave because its location is within the area of Cipicung village. It is known as Siluman cave by spelunkers. Since the Perum Perhutani took over the management of this area, on 26 February 1992, the name of the cave was changed to Wana Wisata Buniayu Cave. Buniayu name itself is taken from the Sundanese language which consists of the word "Buni" which means "hidden" and "Ayu" which means "beautiful". Therefore, Buniayu means "hidden beauty".
