The weather started to be unsupportable from 4000m on - very strong wind and heavy rain, no visibility, on the top at 2pm slightly above zero. Still I continued about one hour to the top just to climb the mountain - came back all wet and totally frozen. Technically very easy hike and well marked.
Still the day before they were searching all night long for a lost girl - found her ok at 7am - she did not pay even one cent to the local indigenous rescuers - volunteers...
I went as a day hike from Popoyán. As I got higher winds were very strong, summit covered in clouds. Went half an hour up from the antenna's. Icy rain, extremely strong wind, no views convinced me to turn back.
