The local populations have closely associated the area, its history and its natural beauty with myths, legends and traditions.Such being the case, the organization of trips around the Prespes Lakes area using solar powered boats can be utilized as an effective tool for increasing attractiveness of the area of interest, aiming at promoting different aspects of the cultural and natural heritage, demonstrating at the same time in real life the endless potentials and advantages of solar power, especially in this part of the world. In this way, it will subsequently contribute to a high increase of the Prespes Lakes area popularity both in the local and foreign touristic market.
