In the 'Dive-with-the-Sharks' program visitors can scuba dive in the large oceanarium, even if they are not scuba qualified. Qualified scuba divers can also 'Dive-with-the-Dugong". The Underwater World also includes a Dolphin Lagoon which is home to some Indo-Pacific humpback dolphins, also known as the pink dolphins.

Fort Siloso

In the west of the island stand the guns of preserved Fort Siloso which guarded the western approaches to Singapore during World War II. Fort Siloso was built by the British in 1880s to guard the narrow western entrance to Keppel Harbour. It was later modernized and by 1939 was armed with two 6-inch Mark2 guns and two rapid firing 12-pounder guns. Fort Siloso is now the only surviving coastal gun battery from the twelve such batteries that made up Fortress Singapore at the start of the war. The ammunition bunkers, barracks, tunnels, and gun emplacements of the fort are now open to visitors, as a military-themed attraction. Also on display is a collection of artillery guns dating from the 17th century to World War II. Life-sized replicas of British soldiers and other people were on display to depict lives at the fort in the past. There is also an exhibition with a large collection of photographs, documents and film clips.

Merlion

The Merlion statue recalls the story of the legendary Sang Nila Utama, who saw a lion in Singapore (originally known as Temasek) while hunting. The 37 metre (12 storey) high statue can be entered through the ground floor, and one can take the lift up to 12th floor to view the city state. It is the tallest Merlion in Singapore.

Beaches in Sentosa Island

Sentosa has a stretch of sheltered beach of more than two kilometres in length on its southern coast, divided into three portions: Palawan Beach, Siloso Beach, and Tanjong Beach. These beaches are artificial, reclaimed using sand bought from Indonesia and Malaysia. Palawan Beach lies in the centre of the southern coast of Sentosa. There is a suspension bridge that leads to a small islet off the coast which is said to be the Southernmost Point of Continental Asia, or Asia's closest point to the Equator. Siloso Beach lies on the west portion of the southern coast and it is known as the place for beach volleyball and other outdoor activities such as canoeing, skim boarding, mountain biking or rollerblading. There are also dining and shopping outlets along the beach. The Shangri-La Rasa Sentosa Resort is located at the western end of Siloso Beach.
