I think Moonlight-canyon is a beautiful nature creation, located in Visegradi hills. Same like Ram-canyon
, although Moonlight-canyon is not so long, and not so narow.
It long is about 500m.
Curiosity of the canyon are the "Y" shaped cave and some carving on the cliff. Theirs ancestry are doubtful.
From Budapest follow the secondary national road No 11. Before you reach Szentendre, turn left to Pomaz. From Pomaz you have to go about 4km, when you reach some houses in the right side of the roadway. After that started the hiking path (about this area choose the 2nd external link).
Mouth of the canyon is about 1.4km form the roadway. There is a little spring where you can fill your bottle.
You can buy a map about this area.
