Хижа Мусала, the Musala Hut, 2430m.
1pm, 20/01/13.
On the ordinary route from Borovets to Musala, at 2925m the highest mountain in Bulgaria, and indeed in the whole Balkan peninsula. I wasn't exactly equipped for alpinism, just walked up from the town in denims and trainers with Kahtoolas, so carrying on to the peak was not an option, though I believe it's an easy and well-marked trail, in summer anyway.
