Getting Around Cambodia: Buses, Rail and River

Buses: the Default Between Towns

Several established private bus operators run frequent, air-conditioned services connecting Phnom Penh, Siem Reap, Battambang, Sihanoukville, Kampot and most other towns of any size, with overnight sleeper buses covering the longer routes. This remains the practical default for most visitors moving between destinations — comfortable, reasonably reliable, and requiring no advance planning beyond a same-day or day-ahead booking in most cases.

The Phnom Penh-Sihanoukville Expressway, Cambodia's first road of its kind, opened in the early 2020s and cut travel time on the country's busiest route substantially compared with the old coastal highway. Elsewhere, road quality varies more: the main routes between provincial capitals are generally in good condition, but rural roads off the main network can still be unpaved and, in the wet season, genuinely difficult.

The Revived Railway

Cambodia's railway, largely abandoned through decades of conflict and neglect, has been rebuilt and returned to passenger service in stages since the 2010s, now running two lines: Phnom Penh to Sihanoukville, and Phnom Penh to Battambang and on to Poipet on the Thai border. Trains are considerably slower than the equivalent bus journey and run far less frequently, but the ride itself — through rural rice country largely invisible from the highway — is a genuinely different way to see the country, and fares are typically lower than the bus.

This is a route for travellers with time to spare rather than a practical default: check current timetables before planning around it, since frequency has changed more than once as services have expanded.

Boats and the Tonle Sap Crossing

A passenger boat route between Siem Reap and Battambang runs across Tonle Sap Lake and up the connecting river, passing directly through flooded forest and floating villages along the way — a slower, more expensive alternative to the road that many travellers rate as one of the most memorable journeys in the country precisely because of what it passes rather than how quickly it arrives. It runs on water levels that shift by season, so the exact experience — and sometimes the route's viability at all — depends on when you travel; check current conditions rather than assuming a fixed schedule.

A separate, generally less-used boat route also connects Phnom Penh and Siem Reap directly via the lake, slower and pricier than the road but a genuine option for anyone deliberately choosing the water over the highway.

Getting Around in Town

Within cities and towns, tuk-tuks are the standard way to get around for visitors, typically negotiated per trip or hired by the half or full day for touring; motodops — motorbike taxis — are the cheaper, faster local equivalent, riding pillion behind the driver. Ride-hailing apps operate in Cambodia's larger cities and are a straightforward, fixed-price alternative to negotiating a tuk-tuk fare directly, particularly useful for visitors unfamiliar with typical local rates. Self-driving a motorbike is possible and common among longer-term travellers, but road conditions and driving norms differ enough from what many visitors are used to that it is worth genuine consideration rather than an automatic choice.
