The Sikkim Himalayas are caricaturized very strongly with the culture of the region. Since the Himalayas are considered holy, attempts to scale new peaks are not looked upon favorably. 

Only two peaks in Sikkim are open to mountaineering expeditions those of Rothong (22,000 ft.) and Kokthang (20,167 ft.) Rothong is immediately to the west of Kabru south and appears to merge with the mean wall of Kumbhakarna (Jano). 

Even though permission for climbing other peaks is not available, it is interesting to know that the greatest peaks of Sikkim lie in five areas: The southern approach to Kanchenjunga, Zemu region, The Kanchenjunga massif, Lhouak in north west Sikkim and the lunar landscapes of north east Sikkim. 

The best known peaks are those of Kanchenjunga (28,146 ft.), Siniokhu (22,620 ft.), Jonsong (24,304 ft), Pauhunri (23,380 ft.), Talung (24,110 ft), Pandim (22,100 ft.) and Tent (24,089ft).
