Nauru is a tiny island country in Micronesia, northeast of Australia. It features a coral reef and white-sand beaches fringed with palms, including Anibare Bay on the east coast. Inland, tropical vegetation surrounds Buada Lagoon. The rocky outcrop of Command Ridge, the island's highest point, has a rusty Japanese outpost from WWII. The underground freshwater lake of Moqua Well lies amid the limestone Moqua Caves.
