Lakes have been centers of civilizations from prehistoric era and are still attracting prosperous cities and traditional fishing-villages around them. Mountainous land is especially favored in lake waters. Tourism is a well-established economic activity in many countries and in a more restricted level in Greek lakes. If, lake-side tourism activities were incorporated in an environmental friendly development policy, aiming at public benefit they could generate an alternative development opportunity in mountain areas. At the bank of lake Zaravina, in Pogoni, certain design proposals are suggested and presented aiming at creating space for open-air activities – walking, bicycling, water and land playing, boating, swimming, diving, picnic, reading, resting. The aim is double: for local residents, to have a place for recreation and spending time in nature; for the lake, to become a local point of attraction for tourists and a reason for tourist regeneration of the surrounding area.
