On Saturday, 21 October we visited Cozia National Park. Autumn nature is amazing, the air is fresh, we enjoyed our hiking a lot. Together with new volunteers from Italy, France, Turkey, Germany and Spain we had a discussion with the authorities of the national park about the environmental problems they face and the solutions they can provide. We realized that in different European countries we have the same problems, that the nature is common and independent, but we are responsible for not damaging it. We visited Arnota monastery with the wonderful look from the hill. We had a rest on the top of the hill and admired the valley with the most silent monastery we have ever seen. The monk from Arnota told us the story of the miraculous appearance of water near the monastery. The monk was praying for water and one day the water appeared. There is a water source in the yard of the monastery with the icon where the story of this miracle is shown.
