is there a chair lift up on the gondola side of the mountain or are they all drag lifts??
i thought i read somewhere that there was a new chair lift but all the piste maps just show drags.
On the markudjik side, the lift for Markudjik 2a & b was replaced last season by a 4 man-chair - it used to be a drag lift before that, which is probably what you're seeing on the piste-maps.
I found a piste map for boro, from it it looks like one going from a point on the musala pathway to the top so you could access the drag bases and one going from this lower station back up to the gondola top.
