A magnificent spot with the road winding under the rock, running alongside a partially underground stream. It's both breathtaking and peaceful. Plus, there's a starting point for a short walk; I did the beginning and it was lovely: I'd love to come back and do a longer section!

Beautiful cave and at the northern exit there is even a waterfall and another picnic area (in the shade, more for summer, in winter we prefer to picnic at the southern exit!)

A place full of charm: a unique cave with the road passing under the rock: you have to go through it, and go through it again!
