Saint John's Island

Saint John’s Island is a small island south of mainland Singapore that has served diverse roles including quarantine station and recreation area. It is part of Singapore’s Southern Islands group and is managed for public recreation and conservation.

The island offers beaches, picnic lawns and short walking paths as its main visitor attractions, together with interpretive signs about the island’s historical uses. It is often combined with visits to nearby Lazarus and Kusu Islands.

Historically the island was used as a quarantine facility and later for other administrative purposes; many of the quarantine-era buildings no longer function but are referenced in on-site interpretation. The island’s role has shifted to recreation and conservation in recent decades.

Saint John’s Island lies off Singapore’s southern coast and is reached by public ferry from Marina South Pier; it sits near Lazarus and Kusu Islands in Singapore’s southern archipelago.

• Ferry access: Regular public ferries connect the island with Marina South Pier on Singapore's main island; crossings typically take under 20 minutes from the pier when scheduled services run.
• Visitor facilities: Visitors should bring water and sun protection and expect basic on-island facilities; there are no large commercial services on the island.
