Super shot Rafa,
we saw one of these on the way up to the Renclusa a few years back but it was in darkness and as soon as it was in our headtorches light, it tried to hide under a boulder.
The one we saw had patches of black and yellow rather than stripes but it was still an exciting moment to see one.
yes. I took early in the morning in a place with shadow. I think that we were the second people crossing the path (a lot of people walks to Ibon de Gorgutes but the trekkers begins to walk late). I liked the brilliant colors. I was also exciting for us.
