The Pelion peninsula, on the eastern side of mainland Greece, is easily one of the most beautiful and unique parts of the country. Interestingly combining the sea and mountain, the region is one where natural beauty thrives. The Pelion peninsula however, is just as unique and stunning underwater as it is above. In the deep blue waters of the Pagasitic Gulf and the Aegean sea, one discovers an amazing undersea world. The Trikeri Diving School is situated in Agia Kiriaki, at the southern point of mount Tesseaon, which is the Pelion extension towards the South.
