Biking Cambodia


Dec 9, 2008
Me and a friend are planning to go Cambodia in July 2009. It would not be a solely biking trip but we would like to do some. A possibly route we have is Bangkok (coming from Ireland) overland to Siem Reap by train and then bus,Temple sight seeing there and then to Phnom Phen and on to Sihanoukville. Flying out of Phnom Phen too Bangkok to head home. We would be going for about 3 weeks.
Any advice on some routes?We would not have bikes with us so we would have to buy a bike or rent some bikes.

Anyone familar with these areas and biking there,or rented biked there?
