Where the buses go
Kim Seng Express runs long-distance services across Cambodia, joining major cities and popular tourist destinations. For Kampot, the routes that matter most are the ones from Phnom Penh and Sihanoukville.
Both cities are common jumping-off points. Phnom Penh is where most overland visitors begin, while Sihanoukville is the gateway to the coast. From Kampot you can reach the pepper farms in the countryside and the nearby Kep area.
Journey time from Phnom Penh
Expect roughly 4 to 5 hours from Phnom Penh to Kampot. The actual time shifts with road conditions and the specific route the bus takes, so avoid booking tight onward connections on the same day.
Buses leave on regular schedules, and services run throughout the week. Check the current timetable at the time of booking, since departure times are not listed here.
What to expect on board
The coaches are described as well maintained and are driven by people who know the local roads. Standard features include:
- Air-conditioning
- Reclining seats with decent legroom
- Onboard entertainment
On longer runs there are short stops for refreshments and toilet breaks. Bring a light layer, as air-conditioned buses can get cold, and keep a little cash handy for snacks at the stops.
