A British tourist endured a gruelling 26-hour sleeper bus journey from Laos to Vietnam.

Chloe Maher, 26, from Liverpool, England, joined other backpackers riding the cramped vehicle through the Indochinese region on February 1.

Footage shows tourists lying in single beds while others sit on the floor in the middle aisle.

The British tourist said: 'So the bus just actually left. I've actually been super lucky. We've got all these poor people on the floor.'

There were passengers under the double-decker beds with more sitting on the back.

Chloe added: 'I was solo travelling but had five friends on that bus with me that I had met. They all sat on the floor.'

Laos faces significant challenges in its public transportation sector due to limited infrastructure and unreliable services.

Last month, a sleeper bus travelling from Vientiane to Pakse lost control and crashed into a tree in Salavan province leaving one dead and dozens injured.

The U.S. Embassy, along with the Singaporean and Australian governments, has issued travel advisories warning about methanol poisoning in Laos.

In November last year, six tourists died after consuming methanol-contaminated alcohol in Vang Vieng.
