Would anybody say Borovets is good for expert? Is there enough challenging runs, or would it be advisable to look elsewhere? I have heard there is a World Cup Run, but is thta the only really hard run available.
It depends what you are after really. It is not a challenging as some of the other european slopes, but you can get plenty of off-piste skiing/boarding if the snow is right. You won't beat it for prices/social though. Mostly Brits, so you get a great atmosphere and no trouble. They had a major competition their last year when I was there, so I guess it must fit someones challenge criteria!
