"“This is a hiker's paradise,” Vassilis Nasiakos, owner of Saxonis Guesthouse, tells me over coffee. In spite of the gathering rain clouds, we forge ahead with our planned trek along Voidomatis Springs Trail. After a short drive to the nearby village of Vikos, we begin our trudge down to the icy-blue river that cuts through the gorge, passing just one other pair of hikers."
