Hanuman Tour Siam

Quick company Intro
Hanuman Tour Siam is a Thai minivan operator that focuses solely on connecting Bangkok with Kanchanaburi in the west of the country. Air-conditioned minivans carry visitors the 130km route to the popular historical town to see famous sights such as the Death Railway and the Bridge own the River Kwai.

Routes served by Hanuman Tour Siam
As mentioned, Hanuman Tour Siam only operates one route but with loads of choice of departure times. There are 21 vans heading in both directions every day all priced at THB163. The first departure in both directions is at 05.00, with a van leaving every 40 minutes until 18.20 so you will never have to wait long for the next van. The journey takes around three hours either way.

Pros
The best thing about using Hanuman Tour Siam to get to or from Kanchanaburi is the sheer number of services each and every day. With just 40 minutes between departures, you know that there is minimal chance of delays as you can simply hop on the next van. Also, it's worth remembering that these vans will leave when full so always get to the bus station early to get a seat. It's not unheard of that you arrive before your scheduled departure to be told that your bus has left as someone else turned up several hours early, you'll then have to wait until the next one. Fortunately, that's never too long.

Helpfully, the website gives you useful information on where to find the check-in counter for these minivans, from where you will be then shown to the van. The check-in desk for Hanuman Tour Siam can be found at counter 19 in Sai Tai Mai bus terminal in the south of Bangkok. That should save you some time wandering around the busy bus station, trying to fight your way through the crowds.

Cons
As is the case when catching a minivan throughout Thailand, you are often required to pay extra for luggage, especially if you are travelling with a large amount. This is because there is very limited space to transport luggage so large items are usually piled onto a spare seat. This means that the van is not filled to capacity so the company will usually charge you a fee. This is also the case when travelling on minivans with Hanuman Tour Siam and is an additional cost that you will need to factor in when planning your journey.

Sai Tai Mai station in Bangkok is not the easiest bus terminal to reach by public transport, so you are likely going to need to pay for a taxi to travel to or from there to your hotel or to catch your next mode of transport. However, if these services departed from Mo Chit you'd end up sitting in traffic for longer and the ticket prices would probably be higher as well.

Keep in mind
Services depart from Bangkok’s Sai Tai Mai terminal and arrive in the Lat Ya area, just outside Kanchanaburi. It's likely that you’ll have to either jump in a taxi or see if your accommodation will arrange to pick you up. If you're meeting anyone, it’s always worth having their contact details handy in case you have to let someone know that you're running late.

What travellers say
Most complaints are due to passengers having to pay extra for luggage, sometimes having to pay for a full-price ticket to put their suitcase on a seat in the minivan. Unfortunately, there is little that can be done about this and is common practice throughout the country. You'll have to consider whether this extra cost is worth it or whether you want to try to find alternative transport to Kanchanaburi.
