Langtang is one of the most unspoiled national parks of Nepal. Situated North of Kathmandu, it is the most easily accessible highland sanctuary from the capital. Langtang covers 1,710 sq. km. forming the upper catchment areas of two of Nepal's largest river systems ? the Trishuli and Koshi. There is great latitudinal variation, starting at 1,500 m. and ascending to the top of Mt. Langtang Lirung at 7,234 m. As a result the park has immense ecological diversity. Some of the most attractive areas of the park include the Langtang Valley, the holy lakes at Gosainkuhda, and the forested hillsides above the village of Helambu.

The deep gorges of Bhote Koshi and Langtang Khola are thickly forested with rhododendron, oak, maple and alder. The stretch of forest around Ghoda Tabela in the lower Langtang Valley and below Gosainkunda is inhabited by the red panda, a rare and threatened symbol of a healthy Himalayan ecosystem. Other animal, common to these forests are wild boar, Himalayan black bear, ghoral, grey langur monkey and leopard. The rare Himalayan hony guide has been sighted here and the park also the home for Impeyan, Tragopan and kalij pheasants among others. Larch, a rare deciduous conifer, is also found in the forest of lower Langtang Valley. Further up, Himalayan tahr, musk deer and snow leopard can be found. The upper Langtang Valley is one of he few known breeding grounds of the ibils bills besides the Tibetan snow cock and snow partridge.
