I was out in Bansko last september/october time. when I was looking around the ski runs I noticed on the large balkan holidays diagram of the ski runs, that there was a long red run off to the right of the main area and it was serviced by a four man chair lift.
now on all the ski run diagrams for this year it seems to have disappeared!
Depressingly they built the run for last season only to discover there was an avalanche risk (someone somewhere deserves a good kicking). It hasn't opened this season either but they are in the process of building avalanche barriers above it (again, why has this process taken a year and a half?)
