Here in Krk, blue sky and turquoise water render a superficially fine impression.
But this is not the Italian Adria, where armies of machinery and men each morning clean the beaches of all kinds of litter brought by nightly winds and waves, in order to maintain the (equally superficial) impression of clean littoral areas. The sad truth is that remainders of human activities of all kinds are returned by the sea to literally every meter of the beach. Sometimes this pieces can be deceivingly beautiful.
