Big Sister's Island, about 39,000 m2 (9.6 acres) in area and also known as Pulau Subar Laut in Malay, faces the open sea, while Little Sister's Island, about 17,000 m2 (4.2 acres) in area and also known as Pulau Subar Darat in Malay, faces the mainland.

The first version tells of two orphaned daughters, Minah and Linah, who stayed with their uncle on an island.

A storm broke out while Minah gave chase to rescue Linah and swam after the boat.

The beaches and warm blue waters make snorkeling a favourite activity at the islands.

Common sea life that can be found includes hard corals, nudibranchs and octopus.
