Directions.The three main entrances are located on the W side of the atoll. Erappu Channel (10°20'N., 169°55'E.), about 4 miles NNE of the W extremity, is the best passage into the lagoon. It is about 0.1 mile wide and, although the depths are considerable, the fairway is tortuous, being divided into several branches by shoals and sunken rocks.
