Siam First

Company Information

Siam First has been operating since 1978, making it one of the most established bus companies in the whole of Thailand. Based in Bangkok’s Morchit bus terminal, Siam First focuses on running services between the capital and the north of the country.

All the buses used on the company's routes are the more exclusive VIP buses that you've probably seen making longer trips up and down the country.

Routes served by Siam First Bus Company

Siam First connects Bangkok with northern cities such as Chiang Mai and Chiang Rai, as well as heading towards the borders with Laos and Myanmar.

Bangkok–Chiang Mai

There are two buses each day from Bangkok to Chiang Mai, arriving at the Chiang Mai Arcade Bus Terminal to the east of the old town. Leaving at 20.02 and 20.32 each day, this trip should take around 10 hours costing approximately THB630 each way.

Bangkok–Chiang Rai

Chiang Rai is even more well-connected. There are 11 services per day running from Bangkok to Chiang Rai, taking 11 ½ hours, three of these buses terminate in Chiang Rai with the others heading towards towns closer to the border such as Chiang Khong (crossing to Huay Xai in Laos) and Mae Sai (crossing to Myawaddy in Myanmar). The three buses that finish at Chiang Rai depart Bangkok at 19.00, 19.20 and 19.50, each costing around THB660.

Bangkok–Lampang & Phayao

Siam First also runs two buses a day to Lampang, departing at 20.21 and 20.51, and Phayao (leaving Bangkok at 19.20 and 19.50). These trips should cost 9 ¼ hours (THB540) and 11 ½ hours (THB620) respectively.

Pros

Siam First is one of the most well respected companies across Thailand with an enviable safety record. VIP buses are used on all routes which means there are fewer passengers aboard than is the case with many of their competitors, making for a more peaceful night. Not only are VIP buses more comfortable than the train, the journey is also much quicker so is a fantastic option if you're planning on a cross-country trip.

When boarding one of Siam First’s VIP buses, you'll be welcomed with a complimentary snack and drink and on some of the newer vehicles there is even a built-in seat massager to relax you throughout your trip. These buses are about as comfortable as an overnight bus trip gets!

For those heading to Laos or Myanmar, Siam First runs regular services north which will suit anyone looking to exit Thailand and explore some of the neighbouring countries.

Cons

Unfortunately, there is no wifi aboard Siam First’s services which can be a pain during such a long trip. Also, with the price of domestic flights continually falling, it may sometimes be better value to book a budget flight as well as being far quicker! It's worth checking flight prices before you book a VIP bus in case there is a great deal on.

Keep in mind

All of Siam First’s services depart in the evening, meaning that you will arrive at your destination in the early morning. Frequent budget travellers will know that arriving at night is usually a hassle, so a morning arrival is handy, although, bear this in mind when booking accommodation as you might not be able to check in until later that day.

If you're planning on crossing into Laos from Chiang Khong or, from Mae Sai into Myanmar, then arriving in the morning allows you to cross the border and travel to your next destination on the same day, so you won't need to book a hotel in a border town, which can often be expensive.

Travellers reviews

Customers are pleased with the reliable service offered by Siam First and are attracted by its reputation as a well-established transport provider.

The standard of the VIP buses is also praised by travellers as it is often a much more comfortable journey than that experienced with some of their competitors. How can you not be happy with massaging seats?!

It is disappointing that wifi is not available on board these buses, a perk that is offered by some of the company's rivals, but hopefully this will change soon!

At 12Go our operators offer three types of service:

Cheap, Fast, Good - but you can usually pick only two of them!
Cheap & Fast won’t be Good. (e.g. buses from/to Khao San Road, local buses or 3rd class trains)
Cheap & Good won’t be Fast. (e.g. VIP trains in Thailand)
Fast & Good won’t be Cheap. (e.g. private limousine services, or VIP24 buses vs Express buses)

Make your choice! Please remember that while we are closely monitoring the services, we are still an agency marketplace. That means we focus on ticketing services and route availability & coverage rather than on the factual seat reclining angle you will get on the bus today.

Highly recommended Bus depart on time, good service. snack, coffee and tea are served on bus. Around midnight they stopped and you have a meal 20mins (included in ticket). The best is comfortable seat and always smile of service woman

My husband's seat would not recline. Driver was all over the road. Bathroom reeked of urine for majority of the trip and the smell eventually crept upstairs to second deck. Bus was EXTREMELY cold. Stewardess was helpful.

Keep your ticket, at midnight you will stop and get free food with. The driver was not driving too fast. It wasn't too cold in the bus. No announcement in English. Counter outside 10 to 12 for the ticket. And 28 to 30 for the platform. You CAN'T charge your phone or connect to the wifi. The chairs were not large but still comfy with massages.

Incredible bus, incredible staff! The bus seats were nicely spaced out, the chairs reclined and even the foot rest raised for you, on top of that there was a built in massager into the chair! It felt so luxurious for such a low price, by far the best bus we’ve been on throughout our travels. On top of that the lady serving us was amazing, she brought hot tea, coffee, cake, wafers, juice and water. Would 100% recommend. The only negative you’ll find is that around 24:20 they stop off at a service station for the driver to eat but they put all of the lights on throughout the bus making you wake up which was frustrating when you’re woken at 530 as you’re nearing the station. Other than that, perfect!

everything was ok except when the steward had to wake us up from sleep during stopover. Probably ask the guest in advance if they want the steward to wake them up in stopover prior to departure.

Comfy bus, and food was nice. Would be nice if there was an English announcement as well as a Thai one. Not sure why we stopped at 12am, would have been nice to sleep through the whole night

It was a bus trip, and this is as good as a bus trip gets. fully reclining seats, a nice hostess, lots of snacks and water, tea and juice. When I had to get off the bus to get food, I was very confused but following the locals and asking helped. Besides that it was a smooth and fast trip.

I am making a review for my trip bangkok chiang Mai now while the bus is moving. The seats are spacious and somewhat comfortable but the bus driver is driving way too fast. I have traveled all over the world, and I have never been afraid of being on a bus before and I can safely say I am scared. He thinks he is a Race Car Driver. He has passed taxi buses and trucks on the highway in the fast lane. At one point, he narrowly scraped thru on the fast lane between passing a bus on the left and the wooden fence on the right. I was afraid for my life, but all other people seemed to be sleeping and didn't notice. The bus was rocking back and forth like a boat! This driver needs to SLOW DOWN and realize there are peoples lives at stake! The hostess was sweet. But due to the speed.. I've never seen such a thing. For this reason I would not take this company again.
