We met the Sofia Green Tour guide, Kaloyan at the National Theatre at 11. He warmly welcomed us, and it was quite nice as he had planned to give the hike in Bulgarian but as our fellow hikers were bilingual, he switched to English.
A short taxi ride (10-11 lv) from the city center takes you to Boyana and the base of the trail to the falls. After a brief talk about the hike, we were in the middle of the woods walking on a not too easy but not too challenging trail over roots, minor scrambling over rocks, and through the trees. You could tell Kaloyan knew his trails as we were on a path with few other hikers but when we reached the base of the falls after an hour and a half, it was packed with people. The falls are pretty, rising about 20m and falling are over a rocky face in a clearing of trees.
The trip to the falls, in retrospect, seemed like a little less than halfway of the hike as we continued up, on easier ground, to a beautiful stone hut with a grill cooking meat outside and delicious soups from a small cafe on the inside. We ate together and Kaloyan shared his insights into Bulgarian culture next to a big wood carving of a bear before heading back down the mountain. The complete hike took about 4 hours .
For families interested, we took our 2 12 year old boys and they loved the hike.
