Swimming pool in Discovery Bay
The pool at Discovery Bay’s Club Siena is jaw-droppingly good. Like five-star resort good. So it’s well-worth 30-minute ferry just to have a splash in the massive outdoor pool with an infinity edge overlooking the South China Sea. It’s brilliant for kids too, thanks to the splash and baby pool, as well as a poolside kiosk to keep them happy. During winter, you can stay warm at the complex’s heated indoor pool with 25m lap lanes. Non-members only need to pay up $100 per day during weekdays and $150 for weekends or public holidays.
