Some of the best hikes I've ever been on! With the exception of Skakavitsa Waterfalls (6000+ feet), every hike was in excess of an altitude 9000 feet! What beautiful scenery from the mountains to the lakes and the hills and the landscapes. Physically demanding but very rewarding.
Traventuria did a great job at organizing the trip for us taking care of all the small details. Our guide, Vladimir, was encouraging, witty, and very patient with those of us who were getting tired - we could not have done it without him.
The food was excellent and the hotels were clean and comfortable. All the transportation was arranged by Traventuria including pick up at the airport.
Only advice i can give for people going outside of Europe is to bring cash to exchange to leva (Bulgarian currency). i brought my debit card but i found it hard to find an international ATM machine.
Overall a great experience and I would highly recommend going with Traventuria. And specifically this tour - Peaks And Lakes Of The Pirin & Rila Mountains
