Compare buses and private cars from Kep to Siem Reap, from about $25 per seat, or split the trip with the Kep train and a night bus from Phnom Penh.

Contents
Kep's crab market and crumbling French villas sit at one end of this journey, the temples of Angkor at the other. In between you cross the whole country: Kampot pepper country first, then Phnom Penh, then the flat rice plains around Tonle Sap.
You can ride through on one bus or minibus ticket, or break the trip in Phnom Penh. Either way it is a full day. You can compare and book the through options on GoAsia.cc.
Kep to Siem Reap by Bus
Through tickets take from about 9 hours 30 minutes to 10 hours 30 minutes, usually with a stop or vehicle change in Phnom Penh. The options are a Universe Luxury coach and minibuses. On booking platforms, tickets cost about $25 to $27 (October 2026).[1] Traffic around the capital is where delays happen, so do not plan a tight connection in Siem Reap for the evening you arrive.
Split the Trip in Phnom Penh
Giant Ibis connects Kep and Phnom Penh in about 4 hours and drops you in Kep Town.[2] The Royal Railway train leaves Kep at 16:35 and reaches Phnom Penh at 19:31; a Normal-class seat costs $9, First Class $17.[3] That is in time for a Giant Ibis night bus to Siem Reap, which leaves Phnom Penh at 22:30 or 23:00.[4] The night bus takes about 6 hours and has bunk beds and an onboard toilet.[5]
Kep to Siem Reap by Private Transfer
A private car skips the stops and the change in Phnom Penh. It takes from about 8 hours 20 minutes, longer with heavy traffic. On booking platforms, private cars and vans cost about $160 to $570 depending on the vehicle (October 2026). Choices run from a 4-seat SUV and a 7-seat van to a 20-seat minibus, which makes sense when a big group splits the price.[1]

- Pack for a long day: Bring water, snacks and a power bank. On a shared minibus, a small bag fits better than a big suitcase.
- Leave slack in Phnom Penh: Traffic on the way in and out of the capital decides whether you arrive on time.
