Were only in the lower one, but it was already convincing. Several branches and really many meters long. It's worth it. There is no treasure, but the way is the goal

You should take off your rucksack before crawling through, otherwise you will rub against the very low tunnel ceiling with it.

Valuable slate that had not yet been exposed to wind and weather was once mined here in the tunnel. Nowadays, a grille prevents people from entering the tunnel. But bats can count themselves lucky, because this measure has given them a home.

A steep path leads up to the left of the tunnel. There are 2 more tunnels about 20m away, which are worth looking at. Especially for the "little" cyclists among us. I have also attached photos to this highlight. 😉
