Greece's outdoor landscape extends well beyond the obvious island beaches. The Vikos Gorge in Epirus — recognised by the Guinness Book of Records as the world's deepest gorge relative to its width — is a day hike through a landscape of vertical limestone walls, clear river, and stone-arched villages above. The Samaria Gorge in Crete is the most walked trail in Greece and delivers 16 kilometres of descent through Europe's longest gorge to the Libyan Sea. The Zagori region's network of Byzantine cobblestone paths connects stone villages through highland terrain that surprises almost everyone who reaches it. The island of Ikaria has one of the world's highest concentrations of centenarians and a hiking trail network that maps their daily movement between villages. Tours by locals who know the landscape beyond the obvious map pins reveal the hidden gems. It really hits differently.
