Langtang is the closest trekking region to Kathmandu, indeed the Langtang trek can be started in Kathmandu itself.
From Sundarajil, just outside Kathmandu the fourteen day trek follows the Shiva pilgrim trail for 150 kilometres, over the Shiva Puri Ridge, over the Gosainkund Lekh via the Laurebina Pass at 4,700 metres.
The Langtang Trek provides an opportunity to see the nearly whole Nepalese Himalayan mountain range from Annapurna in the west, to Makalu in the east. On the morning of the second day, this amazing view can be seen for the first time from the top of the Shiva Puri Ridge.
The trek continues along a high ridge for 6 days until it crosses the Laurebina Pass. Just below the pass lies the Gosainkund Lakes at 4,300 metres. The Gosainkund lakes are the object of the Shiva pilgrim trail for they were once visited by Shiva himself. From here, the path descends to Syabru, an interesting village on the crest of a ridge.
