A flat river basin encircled by 10 mountains, how could Serres NOT be mountain-climbing country? Indeed, the alpine clubs here date back to the beginning of the century. There are two major mountain shelters, open year-round, along international hiking paths, as well as established courses for the more intrepid.
Along the Bulgarian border sits Mount Belles (also called Kekrini) at 2031 metres. Further west are Aggistro (at 1294 metres above sea level), Orvilos (1888), Vrontos (1849), Menikio (1963), and Pangeo (1956). In the region’s south and east lie Kerdilio (1091), Krousia (860) and Mavrovouni (1179). Mount Vertsikos is just over the prefectural border in Thessaloniki.
