Provocative:) White Mountains

of sand! Probably the lowest in Poland!!! Słowiński National Park, coast of the Baltic Sea (July). Actually, to get to this point on the (marked) trail, you have to hike for a good few hours, and before you reach a vast sandy beach with great bathing opportunities (a few hundred metres away from this boggy pond), you have to climb - wading through fine sand (barefoot/sandals works best) - over dunes raising up to 40m. Thanks to this little difficulty the beach is virtually devoid of people. BTW The dunes (shifting since the Middle Ages) rank among the highest in Europe and are called Białe Góry, i.e. White Mountains!!!.
