Crossing from Thailand to Laos at the Chiang Khong-Huay Xai border is one of the most popular overland routes in Southeast Asia, serving as the gateway to the legendary slow boat journey down the Mekong River to Luang Prabang. The process is straightforward and well-organized, but knowing the steps, costs, and potential pitfalls beforehand can make your crossing smooth and stress-free.
This guide provides everything you need to know—from transportation options to visa requirements and onward travel—for crossing this border in 2026.
Why Cross at Chiang Khong-Huay Xai?
The Fourth Thai-Lao Friendship Bridge, which opened in December 2013, connects Chiang Khong in Chiang Rai Province, Thailand, with Huay Xai in Bokeo Province, Laos . This modern crossing has replaced the old ferry service and now serves as the primary northern gateway between the two countries.
For most travelers, this border represents the beginning of one of Southeast Asia’s most iconic journeys: the two-day slow boat trip down the Mekong River to the UNESCO World Heritage city of Luang Prabang . The atmosphere at this crossing is one of anticipation and adventure—a place where the journey truly becomes the destination.

The Slow Boat to Luang Prabang
This is why most travelers are here. The famous slow boat journey takes two days down the Mekong, with an overnight stop in the village of Pakbeng.
Current Schedule and Costs :

- Huay Xai to Luang Prabang: 400,000 kip

Scam Alert: When buying combination tickets, never let anyone keep your ticket after the first leg. Some operators use a “double-purchase scam” where they take your ticket, and the next day’s crew claims it’s invalid and demands you buy another .

Step 2: Exit Laos
- Present your passport at Lao immigration
