Rules in force · 5Drug trafficking can carry the death penalty in Singapore…

Southeast Asia ↗Drug trafficking can carry the death penalty in Singapore, Malaysia, Indonesia, Vietnam, Laos, Thailand, Brunei and Myanmar; never carry a bag or parcel for anyone.
Southeast Asia ↗Carry a passport valid for at least six months from entry with two blank pages; airlines refuse boarding on less.
Laos ↗Get the visa only from the official government e-visa portal or at the airport or border desk; lookalike sites charge extra.
Laos ↗Carry Lao kip in small notes; small shops, tuk-tuks and markets are cash-only, and Thai baht or US dollars are only accepted at some tourist businesses.
Laos ↗At dawn alms-giving, watch from across the street, keep quiet, never use flash and never touch a monk.

Central Laos is the country's transit middle: the railway and Route 13 north of Vientiane are fast and paved, while everything east and south is slow, dusty and partly restricted. Sleep in Vang Vieng for karst and river days, in Vientiane for flights and the Mekong, and treat Phonsavan, Thakhek and Sam Neua as separate legs rather than day-trips.

Plan the nights

How to split the nights, day-trips and what to do with your bags

Open Plan the nightsClose Plan the nights3 partsNights · Day-trips · Bags

Night sequences

3 nights: Vientiane 1 + Vang Vieng 2 (train both ways)
5 nights: Vientiane 2 + Vang Vieng 2 + Phonsavan 1 by air or a long road day
7 nights: Vientiane 2 + Vang Vieng 2 + Thakhek 3 with the loop

Xaisomboun Province east of Vang Vieng: permission required for some areas, entry can be refused, and several governments advise against non-essential travel.
Route 13 south of Vientiane was badly potholed as of late 2024 under heavy truck traffic; the Vientiane–Vang Vieng stretch was resurfaced and is in good repair as of 2025.
Thieves target travellers in remote spots, notably Route 6 near Sam Neua and Route 7 between Phou Kounh and Phonsavan.
Do not hitchhike; waits are long and buses are cheap.

Day-trips door to door

To	From	Door-to-door p50	Last return	Note
Vang Vieng	Vientiane	75 min	unknown	Laos–China Railway; book a day or two ahead in high season.
Plain of Jars	Phonsavan	45 min	unknown	Sites 1–3 by tuk-tuk or hired bike; go early, sites are exposed.
Kong Lor cave	Thakhek	240 min	unknown	Long day by road; most people sleep at Kong Lor or on the loop.
Vieng Xai caves	Sam Neua	60 min	unknown	Guided tour only; the road is slow and often fogged in.

Bags between cities

No luggage-forwarding culture here; carry your bag or leave it at a guesthouse between loop nights.

Door-to-door p50, 2026 estimate

From	To	How	p50	Note
Wattay International Airport (VTE), Vientiane	Vientiane centre	taxi or tuk-tuk	~20–30 min	The busiest of Laos' three international airports and the usual door into central Laos.
Xiang Khouang Airport (XKH)	Phonsavan	flight from Vientiane, then short transfer	flight ~40 min	Saves the long, winding road to the Plain of Jars; schedules change — check.
Nong Khang airport	Sam Neua	daily flight from Vientiane	flight ~1 h 30	Opened 2024; the practical way into Huaphan.
Vientiane	Vang Vieng	Laos–China Railway	~1 h	Fastest and cheapest leg in the region; passport or ID needed at the gate.
Vientiane	Savannakhet	Route 13 south by bus or minivan	~8–10 h	Road condition varies; a night bus or a stopover in Thakhek breaks it up.
