The best of two worlds? Yes, it is possible to combine Sweden and Norway in a beautiful roadtrip starting in either Trondheim (Vaernes Airport) or in Östersund (Åre Östersund Airport) and taking a rental car for a journey at your own pace.
This tour will take you to some of the nicest mountain resorts of Jämtland Härjedalen – Adventure Sweden, as well as to the mountain city Östersund in Sweden. On the Norwegian side of the border you will get to know Trondheim city and the UNESCO World Heritage site Røros.
