Ferry from Marina South Pier to St John's Island costs S$18 adult return via Singapore Island Cruise. Takes exactly 30 minutes each way with departures roughly every 2 hours starting 9am weekdays, 8:30am weekends. Last return ferry typically 6pm, but check current schedules since times vary by season.

Here's the secret: walk 15 minutes across the connecting bridge to Lazarus Island for actual beach time. The sand is genuine and decent quality, unlike Sentosa's imported tourist nonsense. Free guided heritage tours run first Sunday each month at 2pm, but the island's small enough to explore solo in 2-3 hours.

Essential prep: bring water and snacks since food options are limited to one small cafe near the ferry dock. Getting to Marina South Pier requires bus 402 from Marina Bay MRT (Downtown Line) or a 10-minute walk from HarbourFront MRT.

Way better than fighting Sentosa's artificial beach crowds and monorail chaos. These southern islands feel like a different country entirely — Proper peaceful escape from Marina Bay's relentless development.
