Peak Climbing in Nepal is next step beyond simply trekking; however, it requires basic mountaineering above snow line, using ice axes, climbing boots with crampons, etc. under the supervision of professional climbing guides. Climbing in Nepal has always been a mysterious activity to those looking in from outside. Peak climbing in Nepal offers the best adventure trekking and expedition experience to the both experienced trekkers and novice climbers. The best time for mountaineering expeditions is pre-monsoon when the weather is better especially at altitude although the visibility might be restricted. Autumn is good for slightly lower peaks while winter is cold with short days and early spring might be subjected to seasonal snow storms.
