Chung Nhia Vu Mountain

Chung Nhía Vũ is one of Vietnam's highest peaks at about 2,918 m on the Vietnam-China border in Lai Châu - usually climbed together with Po Ma Lung, through near-untouched forest with 50-metre trees, big clear streams and bamboo groves along the border line.

Pristine Border Forest · One of Vietnam's Highest Peaks · Border Permit Required

Overview

Best time to visit
Go in the dry months, Sep - Apr, when streams run lower and the long stretches beside them are safer and less slippery. From Dec to Mar the forest is at its freshest, with rhododendrons and wild orchids flowering. Apr - May stays mild and comfortable before the heavy rains begin. Skip Jun - Aug: the valley sections and bamboo forest turn treacherous in the wet, and the cold, damp air makes the trek miserable.
Best time of day
Set off before first light. On the usual combined trip with Po Ma Lung, Chung Nhía Vũ is the second summit of a very long day, so every early hour counts.
Entry fee
No entrance fee. Because the peak sits on the Vietnam-China border, you need a border permit and must register locally, which includes a local fee - confirm the amount when you register. Foreign nationals go through the immigration authorities instead (the standard fee for entering a border area is 10 USD per person, usually with a sponsoring organisation), and in practice border peaks are reportedly not opened to them. Most people climb Chung Nhía Vũ on a combined tour with Po Ma Lung, costing about 4,600,000-6,700,000 VND per person (2026 price) - see Wild Adventure, Travel Up and Viettrekking. Check current prices before booking.
Opening hours
No fixed hours. You need a border permit, local registration and a local porter before starting.

About This Place

What Makes Chung Nhia Vu Mountain Special

Chung Nhía Vũ stands at about 2,918 m on the Vietnam-China border in Lai Châu, in what is now Sin Suối Hồ commune (formerly Nậm Xe commune, Phong Thổ district). It is usually listed tenth among Vietnam's highest known peaks, rounding out a list that includes Fansipan, Pu Si Lung, Pu Ta Leng, Ky Quan San, Khang Su Van, Ta Lien Son, Ta Chi Nhu, Po Ma Lung and Nhiu Co San. The mountain forms part of the natural border, near boundary markers 83, 84 and 85.

On paper it doesn't look like much - it isn't the highest, and it has no famous summit view. Its appeal only becomes clear once you're on the trail. Being far from villages, forming a natural barrier with China and managed by the Border Guard, the forest here has stayed almost untouched, with trunks rising around 50 metres.

A Trail That Follows the Streams

Most of the way to Chung Nhía Vũ runs alongside large, clear and very beautiful streams - for many trekkers, that is the best part of the route. Around them you pass Nà Đoong waterfall, bamboo groves, rhododendron and tea forest, and stretches of misty cloud forest. The final section from the junction with Po Ma Lung follows the border, where moss-covered stone slabs line the path.

How to Get There

How to Get to Chung Nhia Vu Mountain

Chung Nhía Vũ shares its approach with Po Ma Lung, and almost every group climbs the two together. Take a sleeper bus from Hanoi to Lai Châu city, then cover the remaining 40-45 km (around 1-1.5 hours on a rough road) to the Bản Lang area, usually by car to your porter's house and then by motorbike to the start of the trail.

Groups typically climb to the junction above the infamous "3-hour slope", summit Po Ma Lung first, then return to the junction and continue for about 3 hours to Chung Nhía Vũ.

Permits for a Border Peak

Because the mountain lies on the border and is managed by the Border Guard, you can't simply walk up. Get permission from the border guard post, register with the commune People's Committee, pay the local fee and sign a written commitment naming every group member - and bring your ID card. At least one porter in each group must be a local villager. Tour operators normally take care of the paperwork.

Foreign nationals

Like the neighbouring border peaks, Chung Nhía Vũ is reportedly off-limits to foreign nationals in practice. The formal route is an application through the immigration authorities (standard border-area fee of 10 USD per person, usually with a sponsoring organisation), passed on to the provincial and local border guards. Speak to an operator well before you plan anything.

What to Expect

What to Expect on the Chung Nhia Vu Mountain Trek

Even though it stays under 3,000 m, Chung Nhía Vũ is widely described as a tough, energy-sapping climb: the distance is long and there are many near-vertical slopes. Combined with Po Ma Lung it becomes one of the hardest trekking trips in Vietnam - one group that did both peaks in 2 days 1 night walked for 18 hours on a single day.

Some sources describe Chung Nhía Vũ alone as a fairly short route that can be summited in a day, but most trekkers experience it as the second leg of the Po Ma Lung combo.

In fine weather the walk along the streams and through the bamboo is a pleasure; in the rain, the valley crossings and bamboo forest become slippery and slow. Conditions can switch within hours - sunshine and clear photos on Chung Nhía Vũ, then cold, ghostly fog back at Po Ma Lung.

Don't underestimate it

Chung Nhía Vũ is easier than Po Ma Lung, but on a combined trip you reach it already tired. Plan 3 days 2 nights unless you deliberately want to test your limits.

Travel Tips

Travel Tips for Chung Nhia Vu Mountain

The simplest way to climb Chung Nhía Vũ is on a Po Ma Lung combo tour, which typically costs around 4,600,000-6,700,000 VND per person (2026) - for example with Wild Adventure, Travel Up or Viettrekking. Check with your operator or porter shortly before you go for the latest on permits and trail conditions.

  • Build serious fitness first - the combo is a long series of steep climbs
  • Long sleeves, long trousers and leech socks for the damp forest
  • Shoes with strong grip on wet rock for the stream-side sections
  • A rain layer and warm clothes, as fog and cold can roll in quickly
  • Your ID card for the permit and commune registration

Insider Tips

Based on real traveler experiences and commonly mentioned advice from multiple visitors.

  • Book a Po Ma Lung combo and do Po Ma Lung first
  • Allow about 3 hours from the junction to Chung Nhía Vũ
  • Pick dry weather - the stream and bamboo sections are much harder in rain
  • ⚠️ Border permit required: get permission from the border guard post, register with the local commune office, pay the local fee and sign a group commitment listing everyone's names. Have your ID card with you
  • ⚠️ Your group needs at least one porter from the local village - this is a requirement, not a suggestion
  • ⚠️ Foreign nationals: this is a border peak, and like Po Ma Lung, Pu Si Lung and Khang Su Van it is reportedly closed to foreigners in practice. The formal application runs through the immigration authorities and then the border guards, with no guarantee - check with an operator first
  • Time needed: same as Po Ma Lung, since most groups do both peaks together - 3 days 2 nights is the sensible plan, 2 days 1 night is an extreme push, and some itineraries stretch to 4 days 3 nights
  • From the Po Ma Lung junction, allow roughly 3 hours to reach Chung Nhía Vũ. Doing Po Ma Lung first and Chung Nhía Vũ second is the usual order
  • Much of the route follows big streams through valleys and bamboo forest - lovely in dry weather, but properly difficult when it rains, so watch the forecast
  • Don't be fooled by the height: under 3,000 m, but the long distance and many near-vertical slopes make it a draining trek
  • Wear long clothes and leech socks, and shoes that grip on wet rock for the stream sections
  • Weather changes fast: one group had sunshine on Chung Nhía Vũ and then cold, thick fog back on Po Ma Lung the same day
