/ Around Trondheim
Any suggestions ? Would Romsdal be possible ?
I doubt there'd be any scrambling near Trondheim it's all low, undulating hills. Plenty of hiking, cross country skiing and water ice (might be too late inthe year for some of these, dont know). If Romsdal is where the troll wall is then it's a bit of a drive away. There is some rock climbing near the airport, as well as the flatanger cave which is probably 2.5 hours away from Trondheim.
Otherwise about 4hrs down the road there's Dovre and the areas around Oppdal, Innerdal and the like.
Some popular examples...
Snøhetta in Dovre could be worth a punt if you can get there in good time, does have bus access. The full traverse goes at N4- (UK HS/VS ish) but the other peaks are generally accessible.
Otherwise Innerdalstårnet is another classic...
Will look at Snillfjord which I admit I've never heard of before.
