Winter is a very special time in Northern Norway. Winter also means skiing, and Narvik can offer some of the best skiing in Norway. The view and light change frequently and no two days are the same. For many people, the northern lights are an unforgettable sight, and in Narvik the sky is especially clear and great for watching at night.
The tourist season lasts from February to April, although May can be fascinating too, often with fantastic dry snow and an unbelievable light lasting well into the evening.
Ski hire
It is possible for adults and children to hire skiing equipment such as snowboards. All equipment is prepared for us. If you would like to book your equipment, please email Narvikfjellet.
Cross-country skiing
There are 12 kilometers of cross country ski run in Narvik. You need to bring your own skis as there is no cross-country hire. However, equipment can be bought at local sports shops in and around Narvik.
Off-piste skiing(非场地滑雪)
In order to explore Narvik’s off-piste opportunities you need to know the dangers when choosing routes. It is suggested that you bring necessary equipment such as a shovel(雪铲)and a GPS locator. Ask Narvikfjellet for an experienced guide. With a guide you can explore Narvik’s special off-piste areas in a safe manner.
Sometimes it is nice to do something different and not everybody enjoys skiing. Then you can go horse-riding, or visit the local museums.
