Tourists that climbed the Bucegi Mountains last weekend were treated with a special sight: the sea of clouds. From the Babele peak, at more than 2,200 meters altitude, tourists could watch the “sea of clouds” below, at 1,900 meters. Weather experts say this is a rather unusual phenomenon for the Prahova Valley. The thick cloud layer at low altitude usually forms in the early hours of the morning, and only a few times a year. The moment when the sun appears from the clouds looks very much like a sunrise from the sea.
