Singapore's first marine park, protecting reefs around the Sisters' Islands. Access for diving is managed, so check current arrangements with your dive centre.
About diving at Sisters' Islands Marine Park
Sisters' Islands Marine Park was established in 2014 as Singapore's first marine park, protecting reefs around Big Sister and Little Sister islands and nearby areas off St John's Island and Pulau Tekukor.
The park is managed by Singapore's National Parks Board (NParks), and access for diving is organised through guided programmes rather than open, independent diving — so it feels more like a protected nature reserve than a casual dive site.
What makes Sisters' Islands Marine Park special
- A guided dive trailNParks has run guided dive-trail sessions in the park, taking small groups along the reef with a guide. Availability and booking arrangements change, so check current details before planning.
- Giant clams and coral restorationThe park is home to giant clams and is part of Singapore's wider coral conservation work, which makes a visit an interesting look at reef protection in a busy port.
- Two islands, one channelThe two Sisters' Islands sit either side of a channel known for strong currents, so diving here is carefully planned around the tide.
Marine life to look for
When to dive
Year-round in principle, but strong tidal currents between the islands mean dives run only at suitable times and through organised programmes.
Getting there
Access is by boat from the Singapore mainland as part of an organised visit. Check NParks for current dive-trail and visit arrangements.
Who it suits
Certified divers joining an organised, guided session. Currents mean good buoyancy and calm air consumption are important.
Local tips
- Book well ahead — guided sessions are limited in size.
- Treat it as a nature reserve: no touching or collecting.
- Ask your SSI centre whether it runs or can arrange visits.
Learning to dive at Sisters' Islands Marine Park

Frequently asked questions
Can I dive Sisters' Islands Marine Park on my own?
Diving is organised through guided programmes rather than independent boat dives. Check current arrangements with NParks or an SSI centre in Singapore.
When did Sisters' Islands become a marine park?
Sisters' Islands Marine Park was established in 2014, making it Singapore's first marine park.
Why are currents strong at Sisters' Islands?
Water is funnelled through the channel between Big and Little Sister, so tidal flow can be strong. Dives are timed for calmer periods.
