I think the transfer took us about 2 hours from Plovdiv to Pamps in March and that was with no snow on the roads. There are no toilets on the buses and it is a bumpy ride!!!!
I think so.
in 2006 when we went, we had bounced all the way up the mountain, went round the last corner into Pamps and found a car over turned on it's roof with a very drunk man trying to pull his family out.
The coach driver did not stop, and squeezed his coach between the car and the side of the road. That woke everyone up! lol
