Much of the region is crisscrossed by imposing mountain ranges and deep valleys, which historically made the interior less accessible but have thankfully helped preserve the time-honoured traditions, rich culture and local way of life. With some of the highest mountains in the country and the stunningly beautiful Oiti National Park, this is an ideal destination for adventurers and nature lovers. In contrast, the eastern part features 200 kilometres of lacy coastline with Blue Flag beaches and ample opportunity for water sports. Fthiotida also has several spa resorts with hot springs, including at Thermopyles, where the 300 Spartans made their heroic last stand against the Persians in 480 BC. Archaeological sites, medieval castles, Byzantine monasteries and picturesque villages complete the picture.
