Tyinholmen is the gateway to the mighty Koldedalen, which ends at the northern end of Koldedalsvannet and the foot of Falketind (2067 m). Koldedalen is characterized by wild untouched nature, glaciers, waterfalls and several spectacular peaks close by. Into the valley follows a 9 km construction road from Tyinholmen, which was built in 1955 in connection with the power development of Tyin. The road is not maintained more than absolutely necessary, but is fully drivable. In any case, this gives easy access to very accessible and unique nature experiences!

In recent years, the road into Koldedalen has also become a very popular cycling route. The road winds into the valley, a not particularly demanding cycle ride, but the nature experience is unique. In here you will probably experience some of the mightiest things Jotunheimen has to offer with Falketind 2067 m above sea level, Uranostind 2157 m above sea level and Hjelledalstind 1989 m above sea level close by! At Tyinholmen you can rent bicycles.

Koldedøla comes from Koldedalsvannet and ends in Tyin. Several beautiful waterfalls can be experienced inland along the road. Koldedøla is also a popular fishing river with trout of excellent quality. There are many attractive places to pitch a tent in here. On good weather days, there is a lot of traffic on the road, so it is important to adjust your speed to the conditions. Beyond autumn, this is also an area suitable for early skiing experiences. On Koldedalsbreen, the first snowfall usually occurs at the end of September. Here, randonee enthusiasts can find the first skiing opportunities of the ski season!
