Leaving the ancient stone faces of Angkor Wat behind for the emerald jungles and turquoise waters of Koh Chang represents one of the most classic transitions in Southeast Asian travel. You move from the dusty, spiritual heart of Cambodia to a rugged Thai island that has managed to retain a sense of wildness despite its popularity. This journey involves an international border crossing, typically at the Poipet-Aranyaprathet gateway, making it a trip that requires a bit of logistical foresight.
The route is a fascinating study in contrasts, taking you through the flat Cambodian countryside, across the bustling border markets, and eventually onto a ferry across the Gulf of Thailand. Whether you prefer the efficiency of a flight or the door-to-door convenience of a private vehicle, the transition from the Kingdom of Wonder to Thailand's Elephant Island is a rewarding trek for any traveler. You can easily compare and book these travel options on GoAsia.cc to ensure your cross-border transition is as smooth as possible.
Siem Reap to Koh Chang by Transfer
For those prioritizing comfort and a seamless experience, a private transfer is the most popular way to bridge the gap between Siem Reap and Koh Chang. This option eliminates the stress of navigating the border with heavy luggage or hunting for local transport on the Thai side. When you book a private transfer, you are essentially securing a dedicated service that manages the logistics of the journey from your hotel in Cambodia to your resort on the island.
The price for this premium service ranges from $288 to $383 depending on the vehicle size and level of luxury. For small groups or families, the Comfort Car (3pax) or SUV (4pax) offers a cozy, climate-controlled environment. Larger groups can opt for a Minivan (7pax) or even a Luxury VIP Van (9pax) for the ultimate group travel experience. The journey typically takes between 7 and 11 hours, a variation largely dependent on the time spent at the immigration checkpoints. While you will still need to exit the vehicle to process your exit and entry stamps at the border, having a driver waiting for you on the other side provides immense peace of mind.
Siem Reap to Trat by Flight
If you wish to minimize your time on the road, flying from Siem Reap to Trat is the quickest method to reach the vicinity of Koh Chang. While there are no direct flights that land on the island itself (as Koh Chang has no airport), Trat Airport serves as the primary gateway. From Trat Airport, it is a short van and ferry ride to reach the island's shores.
Flights are generally priced between $222 and $339 for an Economy class seat. The flight duration itself is relatively short, with total travel times ranging from 3 hours and 7 minutes to 8 hours and 22 minutes, depending on your specific connection and layover. This is an excellent choice for travelers who find long road journeys tiring and want to maximize their time on the beach. Upon landing in Trat, local shared vans are readily available to whisk you to the ferry piers for the final leg of the trip.
Siem Reap to Koh Chang by Bus
For the budget-conscious traveler, the combined bus and taxi option is the most economical way to make the trip. This route is often chosen by backpackers and those who enjoy the grit and rhythm of overland travel in Southeast Asia. The price is significantly lower than other options, fixed at approximately $48.
This journey is a marathon, typically lasting about 11 hours and 30 minutes. It is structured as a multi-stage trip involving a taxi to the border, a bus transit through the Thai side, and a final taxi or van leg to the ferry pier. It is a long day that starts early in the morning, but it allows you to see the changing landscape at a slow pace. While the comfort level is lower than a private transfer, it provides a more local experience of the transit corridor between these two famous destinations.

Tips for Traveling from Siem Reap to Koh Chang
- Border Hours: The Poipet-Aranyaprathet border is generally open from 08:00 to 20:00. Ensure your departure time allows you to reach the border well before closing to avoid being stranded overnight.
- Ferry Schedules: Remember that the last ferries from the mainland (Ao Thammachat or Center Point piers) to Koh Chang usually depart around 18:30 or 19:00. If you arrive late, you may need to stay a night in Trat.
- E-Visa vs. Visa on Arrival: Check the latest Thai and Cambodian visa requirements for your nationality. Having your Thai visa or exemption sorted in advance can save significant time at the busy Aranyaprathet entry point.
- Currency: While USD is widely used in Cambodia, you will need Thai Baht (THB) the moment you cross the border for snacks, ferry tickets, or local transport. There are ATMs and exchange booths at the border, but rates are often better in the city centers.
- Hydration and Snacks: The overland journey can be long and hot. While private transfers often include water, it is wise to carry your own supplies, especially for the bus journey which has limited scheduled stops.
