Phnom Penh to Sihanoukville: Train, Bus and Taxi Guide (2026)

This Hey, it's Cambodia guide is designed to answer a specific planning question quickly, then give you enough context to make the right choice on the ground. Information that changes frequently should always be checked again close to travel.

The quick answer

Road transport is usually the easiest way to reach Sihanoukville, while Royal Railway provides a slower alternative on the southern line. If Koh Rong is your real destination, choose your departure based on the ferry connection rather than treating Sihanoukville as the final stop.

Bus

Giant Ibis currently lists Phnom Penh to Sihanoukville service. Check the latest operator schedule and allow a buffer before any ferry, especially during bad weather or heavy traffic.

Train

Royal Railway lists southern-line passenger service from Phnom Penh. Train travel can be more relaxed than a road journey, but frequency is limited, so confirm the current timetable directly with the railway.

Private taxi

A private car is convenient for groups and for travellers carrying a lot of luggage. If connecting to a ferry, tell the driver which pier or operator you need rather than simply saying Sihanoukville.

Sihanoukville or Koh Rong?

Practical planning tips

• Check opening times, schedules or entry rules again shortly before you go.
• Save important addresses and confirmations offline in case mobile data fails.
• Use exact map locations rather than relying only on a venue, hotel or terminal name.
• Build some buffer into transport days and avoid stacking two time-sensitive connections.
• For changing prices, treat quoted figures as a planning reference rather than a guaranteed fare.

How this guide is maintained

We separate stable advice from details that change quickly. Transport timetables, visa rules, promotions, prices, opening hours and review counts can move without warning. For those details, official operators and current local listings take priority over old screenshots or forum posts. This article is part of our 2026 Cambodia planning collection and is updated when material information changes.
