I left Pasto on the bus at 7am, got to the trailhead by 9am to be at the lake around 11.30. There were clouds coming in from the east, but the lake stayed pretty much clear of them. A young dog accompagnied me all the way from San Roque and back! It was great to have him with me. I was there all alone untill the time I left, when I met some people on the way down. Back at the trailhead I was lucky as a taxi (with one passenger already) passed by. He took me to Túquerres for less than a dollar.
