Snorkeling in Singapore
Including Chek Jawa Wetlands and Sister's Islands Marine Park. On the map.
The vibe
Peering beneath the surface here offers a murky, industrial glimpse of marine life where visibility is often limited by bustling shipping lanes and busy port activity. It is very much an occasional, DIY diversion rather than a dedicated island-hopping holiday, best attempted during the drier inter-monsoon months when the water clears slightly. You will mostly spot small reef fish near sheltered jetties rather than vibrant coral gardens, surrounded by the hum of distant container ships.

While primarily known for intertidal walks, the shallow seagrass lagoons and mangrove fringes at Chek Jawa offer unique snorkeling opportunities during high tide. Snorkelers can observe juvenile fish, seahorses, and various crustaceans hiding among the mangrove roots and seagrass beds.
Access. Take a bumboat from Changi Point Ferry Terminal to Pulau Ubin, then rent a bicycle or take a taxi to the Chek Jawa visitor center.
Notes. Snorkeling is only viable during high tide; check the tide schedule carefully as the area becomes a mudflat at low tide.
Sister's Islands Marine Park

Singapore's premier marine conservation area offers guided intertidal walks and designated lagoon snorkeling where you can spot hard corals, giant clams, and anemonefish. While visibility varies due to busy shipping lanes, the restored reef flats host surprising marine biodiversity.
Access. Accessible via chartered bumboat from Marina South Pier, usually arranged through NParks guided walks or private local operators.
Notes. Strong tidal currents can occur between the islands; snorkeling is restricted to designated safety zones and guided slots.
