S1 Bus Bangkok

S1 Bus is Bangkok’s shuttle bus service that connects Suvarnabhumi International Airport (BKK) with the city’s historical core. The cheapest method to go from Suvarnabhumi Airport to Khao San Road and Sanam Luang is to take Bangkok Bus S1.

In This Post

The S1 Bus Bangkok route is the most cost-effective method to go from Suvarnabhumi Airport to Khao San Road and Sanam Luang without changing public buses or utilizing another type of public transportation.

The Airport Rail link train is a less expensive option for getting into the city center. It does not, however, travel to Khao San Road and is not suitable if you have a lot of luggage. As a result, the S1 bus is the most cost-effective and time-efficient route to go from Suvarnabhumi Airport to the Phra Nakorn region, which includes Khao San Road, Phra Arthit Rd, Samsen Rd, Lan Luang Rd, and Sanam Luang. Particularly if you have bags and don’t want to change buses or take a taxi or tuk-tuk part of the route.
