The Home Department of Sikkim has designated five newly opened Alpine Peaks to encourage small expeditions. They are:
Frey Peak 5830m (Chaunrikiang valley)
Tinchenkang 6010m (Thansing valley)
Jopuno 5936m (Thansing valley)
Lama Wangden 5868m (Lachen)
Brumkhangse 5635m (Yumthang)
The peak fee is relatively modest at USD$350 for a team of four. The regulations for climbing these peaks can be found at http://sikkim.gov.in/. Go to the section Government and click on Old Gazettes. Then click on 2006 and all the gazettes for that year will appear in a PDF document (http://sikkim.gov.in/asp/Miscc/sikkim_govtgazettes/GAZ/GAZ2006/GAZ2006.pdf). Go to page 90, and the gazette dated 29th March 2006. This contains the application forms, guidance notes and schedule of fees.
More peaks may be added to the list. The Sikkim Amateur Mountaineering Association is a young and growing organisation that can help visiting climbers, and will appreciate help from visitors (e.g. some equipment donations).
