Bangkok S1 Bus Route

Bus Stop at Suvarnabhumi Airport
The S1 bus at Suvarnabhumi Airport parks on the first floor (Level 1) of the passenger terminal (Gate 7). To take the bus, you need to get out through the door.
After exiting the terminal building, you will notice several taxi and bus counters on your right.
Between the counters of the public taxi and electric taxi, you can find the counter of S1 Bus Bangkok.
Sometimes you might find staff sitting there, but it's not always the case. Even if there's no one to answer your questions, the most important information about the bus service is visually provided. Pay attention to the top of the counter, as the expected time of the next bus departure is presented there.
To take the bus, you need to cross the road. There is an S1 bus information board and often an orange bus parked on the left from the crossing.

Route from Suvarnabhumi Airport to Khao San Road
On the route from Suvarnabhumi Airport to Khao San Road, the S1 Bus Bangkok goes by the expressway before getting into the city center at Bangkok Midtown Hotel.
After getting down to Phetchaburi Road, the bus passes Urupong Railway Station and turns to Lan Luang Road. Along the road, Royal Princess Larn Luang is passed while the S1 bus route continues to the famous Phan Fa Lilat Bridge next to Wat Ratchanatdaram Worawihan with the Golden Mountain, or Wat Saket, on the left.
You can drop off at the Wat Ratchanatdaram bus stop on Ratchadamnoen Klang Road if you are staying at the well-rated Siam Champs Elyseesi Unique Hotel or Here Hostel Bangkok, as both of them are located nearby.
After passing the Democracy Monument, the S1 bus turns right from Ratchadamnoen Klang Road to Thanon Tanao Road to start the route around the Khao San Road area. Depending on the location of your Khao San Road hotel, you can drop off at Wat Bowonniwet, Khao San Road, or Wat Chana Songkram bus stop.
The S1 bus route departs the Khao San Road area by Chakrabongse Road, gets into the main Somdet Phra Pin Klao Road, makes a U-turn just before the Somdet Phra Pinklao Bridge, and ends the trip at Sanam Luang Bus Terminal.
Route from Khao San Road to Suvarnabhumi Airport
Pay attention that the S1 bus route from Khao San Road to Suvarnabhumi Airport is different, as after departing from Sanam Luang Bus Terminal, the bus is going to Phra Athit Road along the Chao Phraya River and passes Riva Surya Bangkok, which is most probably the best hotel in the Khao San Road area.
The S1 bus makes a stop at Phra Arthit Pier (you can get there by Chao Phraya Express Boat) before continuing the route to Phra Sumen Fort and turning to Phra Sumen Road. The bus turns right and passes the Khao San Road area by Chakrabongse Road before getting to the main Ratchadamnoen Klang Road and continuing all the way to the expressway that is used for reaching Suvarnabhumi Airport without any other stops.
Bangkok S1 Bus Price
The current Bangkok S1 bus ticket price is 60 THB per person.
The ticket can be bought on board. Normally, the bus fare needs to be paid by cash only, but now they should be accepting major credit and debit cards too.
Bangkok S1 Bus Timetable
Bangkok S1 bus service operates daily, from 06:00 to 20:00*.
The expected frequency of the S1 bus was every 30 minutes. However, it is now advertised that S1 buses should depart from Suvarnabhumi Airport every hour, even if some travelers suggest that their waiting time was longer than that. Normally, you can see the expected departure time of the next bus displayed at the airport bus counter.
The journey to the final destination usually takes about 1.5 hours, depending on traffic conditions.
Important! *The noted S1 bus service time from 6:00 to 20:00 is for departures from Suvarnabhumi Airport only! From Sanam Luang (Khao San Road), the S1 bus departs approximately 1 hour later (approximate service time - from 07:00 to 21:00).
Bangkok Airport to Khao San Road Travel Options
Suvarnabhumi Airport is connected to Bangkok City by the train, which is known as the Airport Rail Link. If you're arriving at Suvarnabhumi Airport or departing from it, the easiest and cheapest way to travel from/to the airport is by taking the Airport Rail Link. However, you need to change to a bus, taxi, or tuk-tuk if you want to reach Khao San Road from the last Airport Rail Link station (Phaya Thai). For more detailed information, check how to take the train from Suvarnabhumi Airport.
If using public transportation seems to be too complicated for you, book a private transfer online, and the driver will be waiting for you at the airport holding a sign with your name on it. It's definitely the most comfortable way to reach the city and not get lost in Bangkok on the first day of your trip. Private transfer from Suvarnabhumi Airport to Khao San Road can be booked here: Private Suvarnabhumi Airport Transfer to Khao San Road.
At the airport, you might also notice another bus service offered - Limobus. Actually, outside the first floor of Suvarnabhumi Airport, they even have a waiting area with a huge sign "KHAOSAN" on top of it (see photo below).
Even if the sign might confuse you, it's not the same service as the S1 bus! The trip on this bus is much more expensive, and the company is very badly rated online for not keeping their promises about departure times.
