I had chosen the Quarry of Márianosztra, because it has a very
nice view on the danube bend and on the mountain Börzsöny.
You may approach it from Márianosztra (12th main road, then a dirt
road - N 47°51,664' E 18°52,858). If you are with car, you might
park at the beginning of the mud road. (N 47°51,664' E
18°52,858).
The beginning is quite easy, just a little comfortable walk, but
later it becomes more and more dangerous (don't try it with
small children).
Have a really nice caching, Cuni and Fec (the
hiders)
