Saint John's Island, Marine research facility on Saint John's Island, Singapore.
Saint John's Island is a small research island featuring coastal habitats and tropical forests alongside marine science laboratories. The site combines natural ecosystems with facilities dedicated to studying ocean life and aquaculture.
British authorities established a quarantine station on the island in 1874 to manage disease outbreaks among arriving immigrants. This early role as an isolation center shaped the island's identity as a specialized facility for decades.
The island serves as a working research hub where scientists actively study the region's marine ecosystems and biodiversity. Visitors can observe how the research facilities blend into the natural surroundings.
The island is reachable by ferry from Marina South Pier with a journey of about 30 minutes. Bring water, snacks, and sun protection, as on-site facilities for supplies are limited.
Visitors can walk to neighboring Lazarus Island via connected paths and discover its undeveloped beaches. This link allows exploring two contrasting islands in a single trip.
