About This Flight
The Kathmandu to Syabrubesi helicopter flight is the fastest way to reach the gateway of the Langtang region, a scenic transfer that replaces a long, bumpy mountain drive with a single comfortable hop along the Trishuli corridor. The helicopter takes off from Tribhuvan International Airport, climbs north over the middle hills toward Rasuwa District, and sets down at Syabrubesi, the riverside village at 1,460 metres where the Langtang Valley Trek begins, in roughly half an hour. On a round tour you spend an hour exploring the village before returning; on the popular one-way option you start your trek the same morning. As every flight is influenced by the weather, the exact duration may vary depending on visibility, wind, air traffic, and the flight route assigned on the day of departure.
The Kathmandu to Syabrubesi helicopter flight exists because Syabrubesi is the classic trailhead to Nepal's first Himalayan national park. Reaching the village overland takes 7 to 9 hours of road driving through Trishuli Bazaar and Dhunche, while helicopters fly the same journey in about 30 minutes over the deep Trishuli river valley and its forested ridges. The village sits at the confluence of the Bhote Koshi and Trishuli rivers and marks the point where the road gives way to the footpaths of the Langtang Valley, the Tamang Heritage Trail, and the sacred Gosaikunda lakes. Flying in means arriving fresh, on the correct starting point, and with the whole day ahead instead of one spent on wheels.
We operate the Langtang helicopter tour from Kathmandu with the same care and safety standards as every Mountain Helicopters Nepal flight, from the pre-flight briefing to the final landing. On the way your route passes the gorges and terraced settlements of Rasuwa before the Himalayan wall of the Langtang range appears ahead: Langtang Lirung, Langtang Ri, and Ganesh Himal on clear days. It is especially popular with trekkers bound for Langtang or Gosaikunda, travellers short on time, photographers, and anyone who wants to sample the easiest high-Himalayan valley in Nepal without a day of rough road travel.

Tour Feels Like
Passengers enjoy a comfortable and scenic helicopter flight aboard a modern helicopter operated by experienced professional pilots with years of flying in Nepal's mountain country. The journey is smooth and efficient, combining convenience with some of the most accessible Himalayan valley scenery in the country. Throughout the flight, the pilot ensures a safe and enjoyable experience, allowing travellers to relax and watch the river corridor open toward the snow peaks.
Shortly after takeoff, the Kathmandu Valley gives way to terraced hills and the winding Trishuli gorge, where the switchback road below reminds you just how much ground the helicopter is saving. As the flight continues, the villages of Rasuwa grow sparser and the first high ridges close in, the Dalai Lama-prayer-flag settlements announcing the approach to the Tibetan border country. While occasional light turbulence may be felt when flying through mountain terrain, this is a normal part of helicopter operations, and flights are conducted only when weather conditions are considered safe.
Upon landing at Syabrubesi, you step out beside the meeting of the Bhote Koshi and Trishuli rivers. After safely disembarking under the guidance of the flight crew, you can stroll between the Old and New quarters of the village, sip tea among the tea houses, and stand at the threshold of Langtang National Park before re-boarding for the return to Kathmandu - or setting off up the valley on foot.

Health, Safety & Altitude Guidelines
At Syabrubesi, the atmospheric pressure is roughly 85% of sea level, so the air has enough oxygen for most people to walk comfortably without altitude symptoms. Altitude sickness is not a practical concern at the village itself, and the real exposure on the Langtang routes begins only well above the valley floor, beyond roughly 2,500 metres on the way to Kyanjin Gompa. If you are continuing up the valley, give your body the time it needs to adapt at the higher lodges.
Consult the doctor for any of these if you:

ASK US DIRECTLY→Yes, the flight can be arranged daily, subject to morning weather, landing-site conditions, helicopter availability, and flight permissions. It operates through the spring and autumn seasons with shared departures, and private charters can fly on the date of your choice.
The helicopter departs from Tribhuvan International Airport, with the exact helipad, reporting point, and meeting instructions confirmed before the flight.
Syabrubesi is the gateway village of the Langtang region, sitting at the confluence of the Bhote Koshi and Trishuli rivers as the official entrance to Langtang National Park - Nepal's first Himalayan national park - and the starting point for the Langtang Valley, Tamang Heritage Trail, and Gosaikunda treks.
Yes. The one-way option lands you at the trailhead of the Langtang Valley, Tamang Heritage Trail, and Gosaikunda routes in a single morning, where our team and guide support you with permits and porter arrangements for the trail ahead.
Flights operate only when conditions are considered suitable for safe operation. If weather, visibility, wind, or other operational conditions are unsuitable, the departure may be delayed or rescheduled.
Let our experienced team create your unforgettable Himalayan journey.
At the airport, please have your passport and any required permits ready for check-in. Any items not required for the flight can be securely stored at your hotel; only a daypack or small trek bag should be carried on board. You will be guided to the helipad area, where our ground team confirms your boarding details.
Boarding procedures include how to board the helicopter, where to stand, how to fasten and unfasten the restraint belt, how to communicate with the crew, and what to do when you hear the crew's instructions.
The helicopter climbs north from Kathmandu, following the Trishuli river corridor through the middle hills of Rasuwa District to the confluence village below. Airborne time is normally about 25 to 35 minutes. The actual track and duration may change depending on cloud cover, wind, and air traffic control instructions.
The helicopter sets down at Syabrubesi, 1,460 metres above sea level. After landing, passengers remain seated until the crew confirms that it is safe to leave. You have approximately an hour on a round tour to walk between Old and New Syabrubesi, meet the Tamang community, and see the river confluence before re-boarding and returning to Kathmandu.
For one-way passengers, the landing at Syabrubesi is the true start of the adventure: the guide and support team meet you at the trailhead, help you finalise the Langtang National Park entry permit, and organise porter support before the trail continues toward Bamboo, Lama Hotel, and the high valley of Langtang - or, on the opposite ridge, to Sing Gompa and the sacred Gosaikunda lakes. Travellers are advised to allow a reasonable time buffer in their itinerary in case the helicopter arrives later than scheduled due to weather or operational conditions.
Entry to the Langtang region requires the Langtang National Park entry permit from the checkpoint at Syabrubesi, and the Kathmandu to Syabrubesi helicopter price never includes permit fees or the TIMS card required if you continue trekking. Our team can arrange trekking permits and the TIMS card on request, and the crew will confirm exactly which documents you need for your plans.
