Athens - Kalavryta 190 km / Athens - Diakopto 160 km Vouraikos gorge is carved in the conglomerate rocks of the North- ern Peloponnese. A rack railway that was built in the late 19th century crosses it from end to end, through wild landscapes with cliffs, waterfalls and the river flowing below. The 22 kilometers trip from Diakofto to Kalavryta lasts one hour. Next to the rail line is a waymarked path (E4). The downhill walk takes about 6 hours.
