Trail Reviews

Franz Stuffer

August 12, 2022, Praz da Nus

It is better to take this path in reverse. This time I did it from here to be able to mark the climb in an online challenge. But on the other hand it's much better. Even going to Praz doesn't make a lot of sense. If one wants to stretch once in Lignan instead of going down, turn left towards Porliod and can climb a little longer on a climb that is however demanding but with a better landscape.
