The Bangkok bus network can take you to any part of the capital city and its suburbs. The size of the city and the huge number of bus routes shouldn’t scare you off of using public buses in Bangkok. Explore the most useful Bangkok bus routes listed below, as at least some of them might be perfectly suitable for your trip plan.
Bangkok Bus Service Providers
Public bus services in Bangkok are operated by the governmental Bangkok Mass Transit Authority (BMTA) and private operator Thai Smile Group (also called Thai Smile Bus), which was established in 2020 and jointly invested with 8 original private bus companies with licenses to operate public transport routes.
If you prefer a more tourist-friendly way of exploring main Bangkok attractions by bus, you can choose one of the Bangkok hop-on hop-off bus services. Simply book online a Bangkok Hop-On Hop-Off Bus Ticket and see the most famous attractions in the city at your own pace for 24, 48, or 72 hours.
