Unlike other trekking area in Nepal there are no
reliable flight options into the langtang region. There
is a deserted airstrip about an hour beyond Kyanjin
Gompa that used to be served by STOL aircraft, but it is
now totally out of service. Helicopters occasionally fly
to Kyanjin Gompa on sightseeing trips.
Langtang region predominantly lies in Rasuwa district of
Bagmati zone. 6 to 7-hour drive from Kathmandu to
Dhunche in Rasuwa district is the most convenient
approach to Langtang. From Dhunche it is about three
days trekking up the gorge of the Trisuli River (or the
Bhote Kosi as it is known above Dhunche) to Langtang
Valley. The spectacular track up this gorge once formed
an important trade route to the Tibetan fort at Kerung,
just over the Chinese border at Rasuwagadi. The trail
passes through a dense forest of oak, birch and pine,
hung with Spanish moss and hosting delicate orchids.
Further on, the valley opens out into alpine meadows and
yak pastures. The Park is also accessible from
Sundarijal toward the north east of Kathmandu and from
Melamchi Bazar, about 3-hour drive from Kathmandu.
