Starting around the age of 11 (and no doubt more times to come). Winter, summer, sun, fog, rain, snow, seen it all on this route, sometines on the same day.
Beautiful route beside the lakes and can always carefully venture into the odd mine (very wet and dark). The route has changed over the years and there are now some huge deep rock crevasses. I find with the introduction of the steps at the upper section where it joins the Pyg can be very hard on the knees and when wet/icy dangerous.
