Trekking in Lang tang Region

Lang tang area is toward the north of Kathmandu Valley. The scenery here is spectacular, and the trek more adventurous as fewer tourists visit the area.

The forest in the region have temperate and sub alpine vegetation. Wildlife includes migratory birds, deer, monkey, Thar and Pica. The best time for trekking n the Lang tang area is spring and autumn. Most of the trekking routes in Helambu and Lang tang are well served with teahouse making independent trekking quite possible. But, there are no such facilities in the Ganesh Himal area of Ganja La area.

Ganja La

To cross from Lang tang into Helambu, via the Ganja La pass, is a serious undertaking requiting good equipment and experienced local guides. For three to four days there are no facilities, and groups and their staff must be fully self-sufficient. The crossing of the pass requires the use of technical climbing equipment and trekkers must be skilled in the use of this and be prepared to assist less well-equipped porter staff.

For those who are able to complete the crossing the rewards are some of the best mountain landscape to be found anywhere in Nepal.

The route to Ganja La starts above the settlement at Kyangjin Gompa in the Lang tang Valley (see route description for Lang tang Valley.) The pass is clearly visible from Kyangjin, just to the east of the peak of Naya Kanga. The trail follows a small valley before reaching the glaciated pass where the use of ropes, crampons and ice axes may be necessary.

From the pass the views across the valley to the peaks of the Lang tang Himal are particularly good. In the distance you can see Shishapagma, the only 8000-metre peak entirely in China. (Tibet).

The route then follows the open ridge top of Dukpu Danda, which for most of its length is over 45000 meters altitude. Scattered stone shelters, used as summer shelters by herders, are the only evidence of human habitation. There are several fine campsites along the ridge, which can be used by trekkers and their staff on the trek between Ganja La and Tarkeghayang, the first permanent settlement to be reached. From Tarkeghayang there is the choice of trekking to Malachi Pul or Sundarijal. (See Helambu Circuit trek description)

Getting there

Access to Helambu is particularly easy and quick, Sundarijal, which is one of the most convenient starting points, is an hour's drive from Kathmandu. Other possible roads heads are at are at Budhanilkantha, Kakani & four hrs drive away to Melamchipul.The road then continuous to sybrubesi from Ganesh Himal & Lang tang treks can starts. Hindu pilgrimage site and popular tourist place Goshainkunda can be reached from either of the two routes. However, via Rasuwa more is easier.

Attraction-People and Culture

Also found in large numbers here are the Tamang people who also originated in Tibet but settled in Nepal considerably earlier than the Sherpas.

Attraction-Flora and fauna

The forests of Helambu and Lang tang are a prime example of temperature and sub alpine vegetation. The dense oak and pine forests on the trail up the Lang tang Valley are of particular interest.

Look for deer and monkeys in the lower forests and, perhaps, Thar and Pica the alpine hillsides.
