In reply to SteveJC94:
I was there at the weekend.
It was my first time climbing ice, so don't know exactly how 'good' or 'bad' the conditions were, but there is ice to be climbed.
There were plenty of climbers at both Ozzimosis and Krokan. I've posted some pics on the Climb Rjukan/Tinn Facebook page if you want to take a look
