If you are in Romania, do not miss the natural beauty of the Bigar waterfall ! it is quite unique as the water falls down 8 meters from the hill. It is said to be one of the most beautiful waterfall in the world! It is shaped as a mushroom hat and is covered with moss. I went there in the winter months, and I can imagine it must be even more beautiful during the summer, when the current is calm and the drops are gently falling on the moss.
Where is the Bigar waterfall? You can find it in the Anina Mountains, between the villages Oravita and Bozgovici. The scenary on the road to get there is absolutely lovely!
