The bay is shoal, and sheltered from the wind by Mangarin Point to the east and by Ilin Island.

Magarin Point terminates in a long sandy pit off which the depth is 4 to 5 fathoms. Farther in the water shoals rapidly.

The settlement of Mangarin is only accessible by light boat. The surroundings are marshy, and few supplies are available.
