If you’re headed from Battambang to Siem Reap, or vice versa, Siem Reap to Battambang, it may not be obvious that there’s a quicker alternative to the boat, albeit perhaps less scenic (but a big time saver).
For some reason the Mekong Express bus company’s website doesn’t list a route in Cambodia between Siem Reap and Battambang (as at November 2015)….
However, you can book a ticket with Mekong Express for this very route (Siem Reap to Battambang or in reverse Battambang to Siem Reap) using the generic Cambodian travel ticket booking site, CamboTicket. Very random, but it works – exactly what I did.
Remember, if you are headed to Siem Reap, get in touch with Bros to book him in advance as your tuk tuk driver to cover pickup and your temple tours – details on the booking page here.
