Use the quicklinks below to jump to the desired section regarding transport in and around Muong Lay.
There's no longer an official bus station in Muong Lay, so wait by the intersection of Highway 12 and the Lan Anh Hotel road for a through bus towards Lai Chau (via Phong To), Dien Bien Phu, Muong Te or Sinh Ho.
Buses towards Lai Chau and Dien Bien Phu start at around 07:30 and peter out after mid- afternoon — it's about 3-3.5 hours from either to Muong Lay. Be prepared to wait a few hours.
Note that there's only one departure a day to Sinh Ho — at around 09:00 — and it gets mighty busy.
