Buses are inexpensive, convenient, and cover practically all of Singapore. They run from 6 am to 12 am every day and are frequently the cheapest option. There are additional tourist-friendly bus routes. Trans-Island Bus Services and Singapore Bus Service are the two primary bus operators in Singapore. Most tickets vary from SG$.80 (mostly for non-air-conditioned buses) to SG$1.50 (which is for air-conditioned buses). Buses charge a fixed fare to the destinations shown on the front. The TransitLink Guide, available at most bookshops for SG$ 1.50, has detailed information on bus schedules, routes, and rates. Like the MRT, you may purchase individual tickets or a transport card that allows you to make several journeys.
