Siachen conflict was the reason for the closure of the first route of G-1, Hidden Peak since the 80s. Now it is being climbed through its most prominent route from Gasherbrum Glacier. Gasherbrum La has been the more popular route in the recent years has been the up to the Japanese Culvert or the routes along the north ridge. Which ridge is another alternative which is technically less difficult but it is time taking as the distance between camp and summit is bit long.
The snow face part sometimes also pose the risk of avalanche because of new snow falls on it.
Gasherbrum-II is the lowermost part of Karakoram 8000m. At 8035m it has been declared by climbers as remarkable but reachable peak, much like Cho Oyu in this regard but with a trek to its BC that is said to be the best trek with spectacular views of snow-covered mountains in the world. You must have perfect physical fitness and mountaineering experience. G2 stands in the majestic vicinity of K2 in a close line-up of world's highest peaks in the gigantic corridor of Concordia that is not comparable.
The South Western routes are a bit more difficult on ice and snow mixed faces and ridges once you are above the flat terrain after negotiating the heavily crevassed Gasherbrum Glacier. You may have to choose some steep route sometimes. You can continue climbing on a series of routes and reach a region where camp 2 is arranged. From camp 2 you can climb ice pitched and move on the steeper route from the site of C3 which is around 7490m. The three pitches will then lead to the base of the summit pyramid on eastern route. After this, you will have a straight, wide and snow-covered surface but some offer you narrow routes to reach the summit.
