Manra is approximately triangular in shape, measuring approximately 3.2 km by 2.8 km. It completely surrounds a hyper-saline lagoon without outlet to the sea, containing depths of five to six meters. The island is covered with coconut palms, scrub forest, herbs and grasses, including the species Tournefortia, Pisonia, Morinda, Cordia, Guettarda, and Scaevola. Manra was formerly a functioning copra plantation, though it is no longer.
