Pulau Palawan, also known as Palawan Island, is a slipper-shaped islet located just off the southwestern coast of Sentosa, south of Singapore. It lies approximately opposite Beach Station of the Sentosa Express monorail system, which is between Siloso Beach and Palawan Beach. Palawan is most likely a variant of the Malay word pahlawan, meaning "hero" or "warrior".Originally a reef known as Serembu Palawan, and marked on at least one map as "Palawan Reef", it was renamed Pulau Palawan after land reclamation. The island now has an area similar to that of Pulau Biola, about 0.4 hectares (0.99 acres).

Long Ya Men (simplified Chinese: 龙牙门; traditional Chinese: 龍牙門; pinyin: lóngyámén; Malay: Batu Berlayar) or Dragon's Teeth Gate, is the name Chinese explorer Wang Dayuan recorded for Batu Belayar, a craggy granite outcrop that formerly stood at the gateway to Keppel Harbour in Singapore. In his description, “The strait runs between the two hills of the Danmaxi (Temasek) natives which looked like dragon’s teeth.” From there, the name Long Ya Men or Dragon Teeth’s Gate was born. The rocky outcrop served as navigational aids to ancient mariners sailing through the swift waters of the narrow channel between them, but was subsequently destroyed by the British in 1848 to widen the channel for larger vessels to sail through. In 2005, a symbolic replica was erected by the Singapore government near its original site to mark the role it played in Singapore's maritime history.Long Ya Men was documented in Wang Dayuan's travelogue Daoyi Zhilüe as one of the two settlements of Temasek. It was marked in the Mao Kun navigational map historical maritime annal Wubei Zhi said to date from the voyages of Ming dynasty's Admiral Zheng He. Long Ya Men in the map was also used to refer to the strait between Sentosa island and Labrador Point, and named after a pinnacle of stone that was called Batu Berlayar, which means "Sail Rock" in Malay. Another suggestion is that it refers to the Singapore Main Strait south of Pulau Satumu. The Long Ya Men's unique features was said to have assisted Zheng He in navigating the waters around Singapore during his seven maritime voyages to the west between 1405 and 1433 AD.

Sisters' Islands are two of the Southern Islands in Singapore and are located to the south of the main island of Singapore, off the Straits of Singapore.

The two islands are separated by a narrow channel. Currents through this channel can be very dangerous to swimmers and divers.
