I am from Sofia, Bulgaria.
There is no night skiing in Borovec for now and it is not sure whether there will be this season.
On the other hand there is night skiing every evening on Vitosha, which is a mounthain next to the capital Sofia
I have been looking at the web cam of borovets and it looks like its been snowing to me . Are you in the right borovets ?? We have also been in contact wioth the restaurant there and they said it was really deep ... We are flying out tomorrow and am feeling a bit deflated now
Come on, cheer up. Plenty of snow on the upper slopes and plenty to fall on the lower. Real bummer about the night skiing, still at least you can fully enjoy the apres-ski!!
