The island is also an important conservation site for sea turtles. Previously, the indiscriminate economic exploitation of turtle eggs had caused fewer turtles returning to nest on the island. This has led the Terengganu state government to set up the Koperasi Setiajaya Pulau Redang in 1989, a cooperative aiming to develop and manage socio-economic programmes that could improve the livelihood of Pulau Redang locals without endangering its natural resources.[citation needed]

The waters around Pulau Redang also contain two historic shipwrecks: HMS Prince of Wales and HMS Repulse. The ships were sunk here at the start of World War II, setting the stage for the Japanese occupation of Malaya.

The Pulau Redang archipelago comprises Pulau Redang, Pulau Lima, Pulau Paku Besar, Pulau Paku Kecil, Pulau Kerengga Kecil, Pulau Kerengga Besar, Pulau Ekor Tebu, Pulau Ling and Pulau Pinang. Pulau Redang is the biggest of all the islands in the Marine Park, measuring about 7 km long and 6 km wide. Its highest peak is Bukit Besar at 359 metres above sea level. The boundary of the Pulau Redang Marine Park is established by a line linking all points 2 nautical miles (3.7 km) from the shores of Pulau Redang, Pulau Lima, Pulau Ekor Tebu and Pulau Pinang. The other nearby islands of Pulau Perhentian Besar, Pulau Perhentian Kecil, Pulau Lang Tengah, Pulau Kapas and Pulau Susu Dara are also gazetted and protected as Marine Parks. Today, only the bigger islands like Redang, Lang Tengah, Perhentian and Kapas have resort facilities for visitors. The management of Marine Parks primarily involves protection of the sensitive marine and terrestrial ecosystems by controlling the impact from human activities. These include waste & pollution management and conservation of coral reefs and terrestrial habitats.

The 2000 film, Summer Holiday was filmed on the Laguna Redang resort, and a replica of the tea house now serves as the resort’s gift shop.

The entire resort is built over water on stilts made of Belian Wood commonly called ironwood, laid in certain points so as to minimise damage to the existing reef. In its design, Sipadan Water Village has achieved near utopia in its over-the-water layout, splendid water cottage accommodations with flowered sidewalks, wonderfully prepared Asian and Continental cuisine, and impeccable and personable service.

Sipadan Water Village international staffs of dive guides and instructors pride themselves on knowing the intricacies of their reefs and willing to share their macro subject secrets with anyone interested.

The town was founded in the late 1940s. The name is probably derived from a type of Sea shell – Remis, which is a greyish shell and is easily crushed. It lies on the estuary of the Bruas River, it is believed that the once prosperous Hindu Kingdom of Gangga Negara’s Port of entry was here. The Bruas tree which is no longer found in Bruas is still growing in Pengkalan Bahru, a sleepy village 5 km from Pantai Remis.
