This 15-day walking and educational tour leads us from the East to the West, traversing a less known part of Greece. We climb Olympus, the highest mountain of Greece and the summits of Astraka and Gamila, two of the highest peaks of the Northern mountains of Pindos complex. We traverse the spectacular gorge of Vikos. We visit cultural highlights, such as the Macedonian royal tombs at Vergina and the "floating" monasteries of Meteora. We get to Ioannina, a city located on a lake with an inhabited island. Finally, we arrive to the island of Corfu, a popular destination in the Ionian Sea. Swimming opportunities in the Aegean and the Ionian seas.
