Dive Trails


To encourage a deeper appreciation for Singapore's marine biodiversity, NParks has developed Singapore's first Dive Trail located at Pulau Subar Laut or the Big Sister's Island, Sisters' Island Marine Park.

Shallow and Deep Trails

Two separate trails with varying depths have been established to showcase the variety of marine biodiversity and reed features present in Singapore's waters. Approximately 100m in length, the shallow trail will take divers around a loop to a maximum depth of 6m. The deep trail will reach a maximum depth of 15m.

Divers will be guided through 20 stations marked by signs which will bring their attention to the variety of marine biodiversity and reef features present in Singapore's waters, as well as messages on conservation and responsible diving. Some stations will also engage divers in simple biodiversity or water quality surveys as part of NParks' efforts to encourage participation in our Citizen Science programmes.

Minimum Dive Requirements

To protect marine biodiversity, the Dive Trail is planned for divers with relevant dive experience and a certification beyond entry level from reputable international training organisations. This certification can be obtained by signing up with certified dive centres. Divers are required to have logged at least 20 dives with one local dive within the past two years. Good buoyancy control is essential to ensure that corals are not broken accidentally when diving. To ensure long term sustainability of the dive trails, training dives will not be allowed at the Dive Trail.
