"Offers five free walking tours that give first-time visitors an informative overview of some of Singapore’s most distinctive neighbourhoods, including guided visits to cultural quarters and a Marina Bay route that includes areas of the Marina Bay Sands complex not usually open to the public; walk-ins are welcome but bookings are prioritised, and customised paid private-group tours are available for those who prefer a private experience." - Rachel Eva Lim
