Monte Renoso Trail on Corsica

On one of our first days on Corsica we decided to go for a walk and picked Monte Renoso as the target. We found this route on Komoot. The route from our apartment to the starting point took us along a narrow and tortuous but scenic road which managed to drain most of our battery. The starting point on Komoot was not accessible by car so we decided to go for the 4k alternative which started at a parking of a skiing station. This turned out to be a big mistake because this was no longer a walk but a 3k climb of 20% all the way to Bastani lake, at which point we joined the trail. When we finally managed to reach the lake we ate our sandwiches and turned back. No one felt like prolonging the ordeal further. Downhill was not as strenuous for the lungs but still a challenge because of the steep drops with lots of loose small rocks on the path, not exactly relaxing.
