After we arrived at the glacier, the guide arranged for us to wear hiking gear, and tied a rope from large to small to hike up the snowy mountains and drill ice holes. Watching the guide with the axe I was excited and scared, only to see him slipping in the ice cave with the axe to give us a way anyways in the ice cave drinking a sip of glacier water, watching such a scenery, I think it is still very worthwhile.
