The mountains of Nepal are grouped into different categories depending on their height and under whose authority they lay. The Ministry of Tourism is responsible for the expedition peaks above 6500metres, while the Nepal Mountaineering Association is responsible for mountains that are termed Trekking Peaks. These peaks range in altitude from 5800metres to 6584metres, although one should not be mislead into thinking these mountains can be easily ascended. Expeditions to peaks below 5800metres do not require climbing permits although they will require other forms of permits to enter specific regions. All expeditions are required to pay refundable garbage deposits while expeditions to peaks above 6500metres will also be required to employ a Liaison Officer. The best time for mountaineering expeditions is pre monsoon when the weather better, especially at altitude, although the visibility might be restricted with the pending monsoon conditions. Autumn is good for the slightly lower peaks, while winter is cold with short days and early spring might be subjected to seasonal snow storms. However, in these times of global warming and climate change the seasons are no longer as predictable as they use to be.Today in Nepal it is possible to book onto either a commercial expedition to attempt any of the larger mountains or to attempt a trekking peak with one of the many Nepalese Trekking Agents. If an independent expedition wishes to attempt any of the ‘legally’ open peaks then they should make themselves familiar with the appropriate policies and procedures legally required under the current Nepal Tourism Act (Provisions relating to Mountaineering).
