Nusa Barung: Limestone Island with Spectacular Cliffs Rising
Nusa Barung is a limestone island with spectacular cliffs rising to 325m and some coastal mangrove swamps. The island is about six km from north to south, and 16 km from east to west. Most of the island is hilly; there are several deeply indented bays on the northeast coast which provide sheltered anchorages for visiting fishermen. Because of its limestone substrate, the island is almost completely dry with no rivers and only a few natural ponds where animals may find standing water. Location 8°26′-8°30′S, 113°17′-113°26′E; 5 km off the southeast coast of Java, 45 km southwest of Jember, Jember District, East Java.
