Eco-tourism can easily be adapted to Thessaloniki and its surrounding areas because of its natural beauty and landscape. This form of tourism offers the visitor the experience to explore the beautiful sites of the country and the environment. Eco-tourism is slowly being developed by the lakes of Saint Vassilios and Volvi and in the delta of the main rivers of Axios, Loudias and Aliakmonas. The place is home for thousands of birds, plants and many flowers. Furthermore these places are the essential water resources of the area. The lakes can also be used for fishing and for water-sports.
