beautiful and fascinating place, but it's important to be careful and respect the dangers. I'm glad you and your fiancee were able to enjoy the quarry from a safe distance.
I love the photos you took. They really capture the scale and beauty of the quarry. I especially like the one with the waterfall cascading into the water. It's amazing to think that this quarry was once a working quarry, and now it's a popular tourist destination.
Thanks buddy! Yeah, this is actually quite common with quarries here in Central Europe. When the quarry is mined out, it gets flooded with water (rain water or groundwater) and it gradually becomes a tourist attraction or a place where people go to relax. There is such a quarry in my hometown too and I saw some in Poland as well.
Btw there is no waterfall in the Velka Amerika Quarry, I think what you mean is just a path that connects the edges of the crater with the bottom ;)
