Nadikdik Atoll

Nadikdik Atoll also known as Knox Atoll is the southernmost atoll in the Ratak Chain in the Marshall Islands. It contains 18 islands as well as numerous smaller emergent islets with a total area of 0.98 km², that enclose a largely sand-filled lagoonal basin which covers a total area of 3.42 km².

The atoll measures 11 km in length and is 2 km wide. The atoll consists of a chain of small islets located on the western and northern sides. The largest islets include Aelingeo, Nadikdik and Nariktal.

The atoll is connected by a passage called the Klee Passage to the southern point of Mili Atoll which it was once connected to.

Marshallese from other islands in Mili Atoll inhabit the island for months at a time to produce copra. There is at least one homestead there.
