A 19 year old university student has been found alive after spending more than 37 hours lost in dense forest in northern Vietnam, in a case that highlights both the risks of unmanaged trekking and the effectiveness of large scale rescue operations.

Nguyen Tuan Anh, a student from Hanoi, survived with minimal supplies, relying on stream water, a few snack cakes, and basic survival instincts while navigating one of the country’s more challenging mountain terrains.
A Casual Trip That Turned Dangerous
The incident began as an unplanned weekend hike.
- The student and a friend initially planned a different destination before choosing Tam Dao
- They joined a larger group and followed a difficult, unfamiliar trail
- The route involved steep slopes, dense vegetation, and sections requiring ropes to climb
After reaching a peak at around 1,600 meters, the group began descending. Exhausted and assuming there was only one way down, the student stopped to rest and became separated.

As visibility dropped due to fog and the terrain became more complex, he lost his way.
Survival in Isolation
Over nearly two days:
- He navigated slippery rocks, mud, and dense undergrowth
- He endured cold temperatures and heavy fog at night
- He rationed a small amount of food and drank stream water
- He sheltered in a rock crevice to conserve body heat
Despite the conditions, he remained calm and focused on maintaining a consistent direction.
His approach significantly improved his chances of survival.
Large Scale Rescue Operation
When the group reported him missing, authorities launched an extensive search effort.
- Hundreds of personnel were mobilized, including police, military, and local volunteers
- Eight search teams were deployed across the mountain
- Satellite mapping, radios, and thermal imaging drones were used
- Teams focused on streams and descending routes based on survival probability
After an overnight search, rescuers located him at 7:15 AM on April 21 when he responded to calls from a search team moving along a stream.

He was found conscious but physically exhausted.
Why Tam Dao Is Riskier Than It Looks
Tam Dao is a popular destination near Hanoi, but its terrain can be deceptive.
- Steep gradients and loose ground increase fall risk
- Dense forest and fog reduce visibility quickly
- Multiple intersecting trails make navigation difficult
- Weather conditions can change rapidly
Authorities warn that inexperienced hikers are particularly vulnerable, especially when traveling without guides or proper equipment.
Key Lessons for Travelers
This incident reinforces several practical points:
- Avoid unfamiliar routes without preparation or local guidance
- Do not separate from your group in complex terrain
- Carry navigation tools and emergency supplies
- Follow natural features like streams if lost, but proceed cautiously
Even short recreational trips can become high risk in mountainous environments.
Bottom Line
A combination of calm decision making and a rapid rescue response helped prevent a fatal outcome.
The case serves as a reminder that Vietnam’s natural landscapes offer remarkable experiences, but they require preparation, awareness, and respect for the environment.
