Crystal Cave (Goa Kristal)

Crystal Cave (Goa Kristal) is a natural limestone cave located in Bolok village, Kupang Barat, Kupang Regency, East Nusa Tenggara, about 15 km west of Kupang city. It is notable for its crystal-clear brackish water pool inside the cave, surrounded by stalactites and stalagmites. Sunlight entering through a collapsed roof illuminates the transparent water, making it a popular swimming and sightseeing destination for local and domestic visitors.

Visitors can expect a small natural limestone cave accessed by descending concrete stairs into a cavern containing a clear, calm natural pool. The pool is surrounded by rock formations, stalactites and stalagmites, with sunlight streaming through an opening in the cave roof. The main area is the swimming pool inside the cave, with shallow and deeper sections. The surroundings are dry coastal scrubland near Bolok, with basic local facilities outside the cave entrance.
