Nusa Kambangan (also Nusakambangan, Kambangan island, or Pulau Nusa Kambangan) island is located in the Indian Ocean, separated by a narrow strait off the southern coast of Java island; the closest port is Cilacap in Central Java province. Dubbed by one international journalist the "Alcatraz of Indonesia", the island is notorious for its maximum security prisons, home to convicted murderers, terrorists, drug traffickers, and those convicted in high profile corruption cases.
