By train

Singapore’s MRT (Mass Rapid Transit) system is probably the fastest way to zip around the city. Most of our popular attractions are just a short walk away from an MRT station, making our trains a great way to get around.
Visitors can use the following options for MRT journeys:
1. Get a Singapore Tourist Pass (STP), a special EZ-Link stored-value card which will allow you unlimited travel for one day (S$10), two days (S$16) or three days (S$20).
The Pass can be bought at the TransitLink Ticket Office at selected MRT stations listed here, or at the Concession Card Replacement Office at Somerset station. They are also available daily at the Automated STP Kiosks at Orchard station, HarbourFront station, and Changi Airport station (Terminal 2 and 3) near the Transitlink Ticket Office.
2. You can use your foreign-issued Mastercard® and Visa contactless bank cards issued outside of Singapore for the payment of public transport fares in Singapore.
Do take note that admin fees apply for foreign-issued bank cards— you can check out the details at TransitLink’s SimplyGo website.
3. Adult Stored Value Smartcard (EZ-link / Nets FlashPay): These cost $12 inclusive of card value, and come with a stored value of $7 for you to use on your commutes. You’ll be able to purchase this card at any Transitlink Ticket Office or convenience stores.
