There are no flights or public transportation directly to Xaysomboun. However, roads enter the province from Vientiane Capital, Vang Vieng, Xieng Khouang, and Bolikhamxay, and a series of rides in sawng taews (Pickup trucks with benches) can get you there.
Xieng Khouang and Vientiane Provinces open the door to Long Cheng, while Bolikhamxay and Xieng Khouang serve as the gateway to Tha Thom. Vientiane Capital and Bolikhamxay leads the way to Hom, and Vang Vieng and Vientiane Capital hold the key to Long San. The provincial capital Anouvang in the centre of the province, can be reached from all districts.
The best way to get to Xaysomboun is by motorbike or rented car/truck from the capital. You can also negotiate with tour operators to arrange a personalized adventure from Vientiane and, Vang Vieng.
