Chiang Khong ↔ Huay Xai: the Thailand to Laos border crossing

You change here rather than crossing aboard, and you should budget about 90 minutes for the formalities on top of the journey either side.

How the crossing works

Chiang Khong ↔ Huay Xai

Thailand ↔ Laos
Where
Fourth Thai–Lao Friendship Bridge, by shuttle bus
On the train?
No — you cannot walk the bridge, a shuttle bus carries you across
Luggage
Yes
Visa
Lao visa-on-arrival is normally available here, in US dollars cash. Confirm for your passport before relying on it.
Cash on the far side
Crisp, unmarked US dollar notes for the Lao visa fee, plus kip for the boat.
Time cost
About 90 minutes of formalities

The trap. The bridge is several kilometres outside both towns, so the crossing is two tuk-tuk rides with a bus in between. Do it the afternoon before the boat, not the same morning — the slow boat leaves Huay Xai early and does not wait.

Typical scheduled running time for the crossing leg itself, which does not include the 90 minutes of formalities above. Allow for both when you are working out whether a connection holds. Fares are indicative.

Getting to each side

The frontier is rarely the problem. Reaching it on a day when something onward is still running usually is.
