The climb up to the top of Mount Kouroupa, 1001 meters above sea level, is the hardest walk on this website but the rewarded views are nothing less than spectacular. The radio mast on top is visible from all around Plakias and there also is a little chapel. The walk up starts at Koxare, on the northern side of the mountain. On the way up you pass the ruins of Koredo Castle. Make sure you bring enough water with you!
