Leaving the laid back riverside capital of Laos for the rugged northern reaches of Cambodia is a journey that takes you deep into the heart of mainland Southeast Asia. While Vientiane offers a blend of French colonial architecture and gilded temples, Preah Vihear serves as the gateway to one of the most dramatic mountain temples in the Khmer Empire. This route is not a simple hop across the street; it is a true overland expedition that rewards the patient traveler with changing landscapes and a deep sense of accomplishment upon arrival.
The transition from the Mekong plains of Laos to the forested plateaus of northern Cambodia involves a long haul through the southern provinces of Laos before crossing the border. It is a route favored by those who prefer the steady rhythm of the road over the sterile environment of airports, offering a chance to see the rural life that exists between the major tourist hubs. You can secure your seat for this long distance journey by booking your tickets on GoAsia.cc, ensuring your spot on the combined sleeper bus and minivan service.
Vientiane to Preah Vihear by Bus
The primary way to tackle this distance is via a coordinated transport service that combines a long distance sleeping bus with a minivan transfer. This journey is designed to maximize your time by covering the bulk of the distance overnight, allowing you to rest while the bus traverses the length of Laos toward the Cambodian border. The total journey time is approximately 21 hours and 30 minutes, making it one of the more significant overland treks in the region.
The Sleeping Bus Experience
The first leg of your journey typically involves a sleeping bus. These vehicles are equipped with bunk style beds rather than standard seats, allowing you to lie down flat. For a journey of over 21 hours, this is a significant advantage. While the space can be cozy, it provides the necessary comfort to get some sleep before the border crossing operations begin in the morning. You can expect basic amenities like air conditioning and sometimes a small snack or water, but it is always wise to bring your own supplies for a trip of this duration.
The Minivan Transfer
As you approach the border and head toward Preah Vihear, the transport usually switches to a minivan. Minivans are more agile on the narrower roads of northern Cambodia and are better suited for the final leg of the trip. The price for this entire coordinated service is $87. This flat rate covers the transition between vehicles, though you will need to handle your own luggage and passport processing at the border checkpoint between Laos and Cambodia.

Tips for Traveling from Vientiane to Preah Vihear
- Prepare for the Border: Ensure you have your visa requirements for Cambodia sorted in advance or have the necessary US dollars for a visa on arrival. The border crossing at Nong Nokkhian (Laos) to Trapeang Kriel (Cambodia) is generally straightforward but requires patience.
- Pack Snacks and Water: While there are stops along the way, the selections can be limited. Bring enough water and non-perishable snacks to last the 21 hour journey.
- Keep Valuables Close: On sleeping buses, it is best to keep your passport, money, and electronics in a small bag that stays with you in your berth rather than in the luggage compartment.
- Dress in Layers: Air conditioning on Southeast Asian buses is notoriously cold. Even if it is sweltering outside, you will likely want a hoodie or a light blanket for the overnight portion of the trip.
- Book in Advance: Because this specific route involves coordinated transfers and limited daily departures, booking your ticket a few days ahead through GoAsia.cc is highly recommended to avoid being stranded.
- Arrival in Preah Vihear: The bus will drop you in the town area. If you are planning to visit the Preah Vihear Temple (Prasat Preah Vihear) on the Thai border, you will need to arrange a separate car or motorbike trip from the town, as the temple is located about an hour away on a steep cliffside.
