Hiking
In total, the hike to Kjeragbolten is 9.8km long with a difference in altitude of approx. 460m. It took us about 2 1/2 hours to get there and a little less to get back. The hike takes you up and down several ridges, which makes it quite strenuous. In some places, the rocky surfaces are also very steep and slippery, so you should be careful and ideally always pull yourself up using the chains provided.
Before we arrived at the well-known Kjeragbolten, we lingered on the summit of Kjerag about 300m beforehand. It was much quieter here than at Kjeragbolten.
At regular intervals, you can hear a gunshot-like bang on Kjerag, followed by smoke rising from the rock face. We actually witnessed this, too. The cause of this has not yet been clarified. However, it is assumed that the bang is caused by water coming out of the rock face under high pressure.
