Because there is still not much in the way of a tourist industry in Kampong Cham, visitors will have to arrange their own transport. Motorcycle riders will be able to rent bikes, although many tourists take advantage of the cheap prices and purchase their own bike. Non motorcycle riders, and those who don’t want to risk Cambodia’s sometimes crazy roads can find motorcycle drivers (motodops) to drive them. There are also cars for hire.
Though there are a few temples, the best things to do in Kampong Cham and the surrounding area (Kampong Cham Province) is just to hang out or cruise the countryside. Within the city, it is worth checking out the markets. There is all the hustle and bustle of a Southeast Asian market, but with Kampong Cham’s unique charm and friendly local people. It’s a great place to socialize, even if you don’t speak Khmer. Because this is an outlying area, the food is probably not as safe for a western stomach. However, people who have been in Cambodia for a while, or those who just want to jump in, can find great food stalls at some of these markets. As a general rule, if the place has multiple patrons and seems clean, it’s probably OK.
After a hard day, the improvised beer halls on the banks of the Mekong are the best place to be. Beer is dirt cheap (Angkor, Tiger), and the locals will definitely be around to socialize.
Just cruising in the countryside, past the fruit and vegetable farms, and local villages (including several stilt house villages along the Mekong) is reward enough for most tourists. Those seeking "untourist" attractions will find a couple of temples in the area worth checking out. Thousand year old Nokor Temples is the most famous in the area, but be prepared to wander by yourself unless you happen upon one of the monks who live there.
A cruise on a slow boat (as opposed to a fast one) on the Mekong would be a great way to end a visit to this sleepy but charming ville.
