The hike leads into a valley with around 700 yew trees, some of which are very old. This yew species is autochthonous, so it only occurs in the region (sorry, I'm not a biologist and I'll just keep telling you). In any case, the gnarled trees impressed me so much that I can highly recommend the small tour.
