The cave cannot be reached (or only in a dangerous way). The footpath is on the other side of the L3216, you would have to climb over the guard rail on the road at least once to get to the other side. It's dangerous because the B276 functions as a cross road and the fairly large intersection is very confusing and busy. In addition, there doesn't seem to be any forest or footpath anymore, everything looks very overgrown and impassable. So I've skipped visiting the cave on my tour. What a pity 😔

The Antonius Grotto is a very well-maintained facility. It's a place created out of gratitude. Here you can also take a break in the refuge.

Mines used to be operated in the gold hollow and ores were mined. The tunnels were used by the Americans as ammunition depots after World War II. Today the tunnels are closed and serve as quarters for bats
