I had a great trip in the Rhodopes mountains. The walks were great, the GPD routes well-marked, and there was a lot to extend the walks/days with.
The season was very quite, in three days of hiking I only met two other people, which was a lot less than the tens of fire salamanders along the tracks. Not too many birds, cross bill, peregrine falcon, unfortunately no wall creepers (sad)
If I happen to return to Bulgaria I won't hesitate to contact you again.
