Nepal Himalaya is known as the rooftop of the world. There are 1,310 peaks above 6000 meters of which 238 are already opened for climbing. Likewise, out of fourteen 8000 meters above peaks eight of them, including the highest peak in the world, Mount Everest lie in Nepal. Other seven are namely Kanchenjunga, Lhotse, Makalu, Cho Oyu, Dhaulagiri, Manaslu and Annapurna. For many decades the dauntless icy peaks have posed as challenge to those who dare.

Climbing permit to scale the Nepal Himalayas is issued in all seasons by the Mountaineering Section of the Ministry of Culture, Tourism and Civil Aviation. Certain official documents are required to seek permission for climbing peaks. Climbing gears and equipments can be bought or rented in Kathmandu. Many mountaineering and Utmost Adventure also offer packages that take care of needs like gear, food, transportation, guide and porter services. They also arrange insurance. Visitors should choose an agency that has good track record.

It is a very interesting thing to know that there was a sea (the Tethys sea) between Indian Gondwana continent (Indian sub continent and Eurasian continent). Around 70 and 80 million years ago, the Himalaya began to come into existence. It is a peak of each evolution only about 10 to 20 million years back. Therefore, the Himalaya is extremely young and geologically active. According to geologists, mountains are growing at a rate of 15 cm (6 inch) a year as the Indian plate moving northward and forcing under the Eurasian plate. This process (plate tectonics) causes the earthquakes in this region. Geologists say that the collision of continents is squeezing up sedimentary rocks that were once below the sea. The mountains of Himalaya are the result of the collision of continents.
