In 2017 I did a trip with my dear friend Ilir Hysa, who has been running the Tirana Backpackers Hostel already for many years. We decided to do a short bike trip together. A bit north of Tirana we found this beautiful route. DICLAIMER: we never did day three, from Klos back to Tirana, which seem to be quite difficult. Instead we continued to Burrel (great downhill) and took a mini bus from there back to Tirana.
