Monthly Update (August 2026):
Ubon Ratchathani–Vang Tao remains a relatively quiet road crossing, with no significant new change reported in August. The route continues to be useful for travelers heading between southern Laos and Ubon Ratchathani, although it sees considerably less international traffic than the Friendship Bridges farther north. August rain can slow the roads approaching Chong Mek, so the journey to the crossing can take longer than the border process itself.
About this crossing
A History of an Upland Connection
The history of this crossing is one of a traditional upland trade route connecting the Khorat Plateau of northeastern Thailand (Isan) with the Bolaven Plateau and the Mekong plains of southern Laos. The people on both sides share close linguistic and cultural ties. The modern border crossing grew in importance as infrastructure on both sides was developed. It became a key point for trade and a vital link for the southern provinces of Laos, providing access to the markets and services of Thailand. The crossing's importance for tourism exploded as southern Laos became a popular destination. The ancient Khmer temple of Wat Phou (a UNESCO World Heritage site), the coffee plantations of the Bolaven Plateau, and the laid-back, idyllic atmosphere of the 4000 Islands have drawn an increasing number of travelers, and the Chong Mek-Vang Tao crossing is the most convenient entry point for all of these attractions. It has evolved from a simple local checkpoint into a major international tourist gateway.
The Border Crossing Procedure: A Straightforward Land Crossing
The border is open from 06:00 to 22:00 daily. The process is well-established and accustomed to handling foreign tourists.

You will pass under a large "Welcome" archway.Entering Laos (Vang Tao): The Lao immigration and customs post is a smaller, more functional building. Here, you will need to get your Lao visa on arrival (available for most nationalities) or use a pre-arranged eVisa. The Lao Digital Immigration Form (LDIF) must be completed online in advance. You will go to the visa window, fill out an application form, provide one passport-sized photograph, and pay the visa fee in US dollars. The fee varies depending on your nationality. After you get your visa sticker, you will proceed to the immigration counter to get your entry stamp. The process is generally smooth and straightforward. Once you are stamped in, you are officially in Laos.
