There are plenty of taxis waiting to take you to Chankanaab. They are only able to take four passengers in a car. If you have more (we had 5) they will say you have to take a van which is fine but they tried to charge us $18. When I refused and walked away, he came after me in a few minutes and said he'd made a mistake, it was only $12. Just a little thing that's good to know!
