It’s easy to Crossing Border Chiang Khong to Huay Xai by yourself
In mid-December 2013 a new bridge (the fourth Thai-Lao friendship bridge) was opened across the Mekong linking Chiang Khong to Huay Xai (aka Ban Houayxay) in the Lao province of Bokeo, replacing the previous ferry crossing.
Get in. Probably you will arrive with minibus from everywhere in Thailand, you can kindly try to ask to the driver to bring you directly to the border or go to the close bus station and cross the bridge with the public bus for 25 Bath. According to Thai border officials the border does not close until 22.00 PM, but you cannot cross the border after 8PM with the bus and you will need to find a private car if you are in a hurry. If is not you can spend the night to Chiang Khong that is in a nice location and the guesthouse and foods are quiet cheap. If you want to cross the border with bicycle they will charge you 100 Bath and for the motorbike 200 Bath. Finally crossed the border Enjoy Laos!!!
Get out. Probably you will arrive everywhere from Laos, the border open at 6.00AM and until 8.00AM they will charge you a little commission, the same happens after 4PM and during the week-end (saturday and sunday), border close at 22.00PM. The price for the buses, bicycle or motorcycle are the same. Finally crossed the border Enjoy Thailand!!!
