Another way to explore Kongsberg´s heritage is to hike past abandoned silver mines in the hills above the city. Or get on board the pit railway at Saggrenda, 8 kilometers from the city center, to travel 2,3 km into the mountain and centuries back in time, with a guided tour of the King´s Mine. An exciting experience is the Mining Safari.
This unique adventure is a 5 km (3,25 miles) long walk through the 250 year old adit; "Underbergstollen". The guides from the Mining Museum will tell you what you see as you walk past the old silvermines at a depth of 150 metres (500 feet).
