Laos itineraries: 1 week, 2 weeks and 3 weeks

Pick the length first, then the route. The railway sets the order in the north; the south needs a flight or a very long bus.

Nights below are the minimum that still feels unhurried. Add a night wherever you plan a full-day transfer.

Step 1: choose your entry and exit. Most travellers fly into Luang Prabang and out of Vientiane, or cross to Thailand by rail at the Friendship Bridge. Flying into Vientiane and out of Luang Prabang works the same route in reverse. If you want the south, plan a domestic flight to Pakse rather than a bus.

Step 2: book the railway legs early. The Laos–China Railway links Luang Prabang, Vang Vieng and Vientiane in a few hours each; seats sell out in high season, so reserve a day or two ahead at the station or through an agent. Trains are the reason a 7-day trip works at all.

Step 3: keep one full day per road or river move. Minibus Luang Prabang–Nong Khiaw is roughly 3–4 hours each way; the Bolaven Plateau loop is 2–3 days by motorbike; the Thakhek Loop is 3–4 days. None of these fit inside a 7-day trip without cutting something else.

Step 4: place your nights. Luang Prabang deserves 3–4 nights for temples, alms-giving, the night market and Kuang Si. Vang Vieng needs 2 for caves, kayaking or a balloon flight. Vientiane is one full day. The south: 2–3 nights on the Bolaven Plateau and 3–4 in the 4,000 Islands.

Step 5: sort money and paperwork before you fly. Carry kip for small guesthouses and buses, and check your visa rules for your passport before booking.

Season changes the plan more than the route does. November to February is dry and cool, the best window for the north and the plateau. March to April is hot and smoky from field burning, which matters if you have breathing problems. May to October is wet: waterfalls are full, but some dirt roads and loop sections get rough.

Cash is still king outside the main towns. ATMs exist in Luang Prabang, Vientiane, Vang Vieng and Pakse, but not on the loops or in the islands, so withdraw before you leave. Guesthouses and bus tickets are often paid in kip.

Book the popular places ahead in high season: Luang Prabang guesthouses, sleeper buses and the train. In low season you can usually turn up, but the night you land still decides whether your guesthouse door is open, so have the first night sorted.

Do not stack two long transfers back to back. A Luang Prabang–Pakse day by road is punishing; the flight is short and worth the money if your time is tight.
