From La Colma at first I reached the Randolina then, joggin down, I went to Narteggio bridge on the Sobbia. Following the Sobbia upstream I reached the Molinetto bridge, and came back to La Colma by the foothpath Quadretto-Colma. In the middle of the hike I noticed a tick wich was walking on my leg, and luckily I managed to drive it away before it was fixed on my skin.
