Very friendly people.
The place is kept neat and its safe to visit. The payment process at the entrance is bad and took way to long
This place is so cool and there is gold and german weapons on the bottom. It is 320 ft deep. the territory was once owned by the german.
Very beautiful and interesting place to see.
Nice lake with interesting old engineering equipment. More information about it could be useful
