Mekong River safety: the risks to know in Laos, Cambodia and Vietnam

The Mekong is not a hard trip safety-wise: the main risks are specific and well known. The Myanmar border around the Golden Triangle, unexploded ordnance in rural Laos, methanol in bootleg alcohol, night roads and overloaded boats. Here is what governments advise, and what it means on the river.

Is it safe to travel to Laos, Cambodia and Vietnam?

On the river itself, the answer is mostly reassuring. The State Department placed Laos at Level 2, “Exercise Increased Caution,” on July 28, 2026, citing crime, unrest and unexploded ordnance, with Xaisomboun province, away from the Mekong, at Level 3[1]. Cambodia has been at Level 2 since September 15, 2026, with a “Do Not Travel” warning within 50 km of the Thai border[2]. The Cambodian stops on the Mekong, Stung Treng, Kratie, Kampong Cham and Phnom Penh, do not touch the Thai border. For Vietnam and Thailand, check the current advisories on travel.state.gov[3].

The land border between Thailand and Cambodia, closed since the 2025 conflict, was still kept closed by Thailand in October 2026[5].

The Golden Triangle, the one sensitive area on the route

At the Golden Triangle, the Mekong separates Laos, Thailand and Myanmar. The French government advises against the Lao border area with Myanmar except for compelling reasons, and formally advises against the whole Thai border with Myanmar except Mae Sot[4][5]. The UK government urges extreme caution in Bokeo province, especially around the Golden Triangle Special Economic Zone, because of job scams and drug trafficking by armed groups[6]. In August 2024, 771 people were arrested there in a crackdown on online scams[7]. Check the latest advice before you go.

Unexploded ordnance in Laos: stay on the paths

More than 270 million cluster submunitions were dropped on Laos between 1964 and 1973; 30% did not explode, and only 10% of the ordnance has been cleared[8]. In 2025, the Lao national authority recorded 11 accidents and 21 victims, including 5 deaths; children account for more than 40% of victims[9].

The rule is simple: in the countryside, don't leave roads and busy paths without a local guide, especially near the Vietnamese border, and never pick up a metal object[4][6]. The risk rises after monsoon floods and landslides[6]. Cambodia is also heavily affected by landmines, often in unmarked areas[6]. All the Laos-specific advice, vaccines and medical care included, is in our Laos safety and health guide.

Methanol and tainted alcohol: what happened in Vang Vieng

In November 2024, six tourists, including an American, died in Vang Vieng, Laos, after suspected methanol poisoning[10]. In July 2026, the owner of the distillery that made “Tiger Vodka,” in which methanol above safe levels was found, was indicted; Lao authorities have banned this vodka and “Tiger Whisky”[11][6]. Methanol has no taste or smell, and cases have involved drinks bought in licensed bars, shops and hotels; the UK government also reports cases in Cambodia, Vietnam and Thailand[6].

Slow boats and speedboats: safety on the Mekong

Travel on the Mekong can be dangerous: water levels change, currents are strong and obstacles are hidden underwater[6]. Safety standards vary widely: check that there are life jackets and avoid overloaded boats[6]. On December 18, 2025, a slow boat carrying 147 passengers hit submerged rocks near the Pak Ou caves, upstream of Luang Prabang; a mother and her two daughters went missing[12]. In the rainy season, water levels can rise sharply within hours[6].

On the road: night buses and motorbikes

In Laos, avoid driving at night outside towns and taking night buses; in Vang Vieng, serious accidents happen regularly during activities such as ziplining and tubing[4]. Cambodia has one of the highest road accident rates in Southeast Asia, and motorbike and night bus accidents are common in Vietnam[6]. In Thailand, more than 17,000 people die on the roads every year, and 90% of fatal accidents involve two-wheelers[5].

Job scams and scam compounds

Online job offers can lead to people being held in scam compounds, in Cambodia and along Thailand's borders with Myanmar and Cambodia[5]. Cambodia says it has dismantled these compounds: from July 2025 to August 2026, 624 sites were raided and 58,266 foreigners rescued and deported, though experts remain skeptical[13]. The risk mainly concerns people looking for work, not travelers passing through.

Drug laws: very heavy penalties in all four countries

In Laos, drug use and trafficking can carry the death penalty, cannabis included[4][6]. In Thailand, possessing Class A drugs can also lead to the death penalty; in Vietnam, penalties are severe whatever the quantity; in Cambodia, they can reach life imprisonment[6]. For vapes, banned in all four countries, and drones, see our packing guide.

Questions about safety

Can I rent a scooter in Laos?
Yes, but don't leave your passport as a deposit, the UK government advises. Wear a helmet, and avoid riding at night outside towns.
Is the conflict between Thailand and Cambodia over?
A ceasefire took effect on December 27, 2025, but the border areas remain fragile and the land border was still closed in October 2026. The Mekong stops in Cambodia are not affected.
