The Samaria Gorge is the most famous day trip from Hania and one of the great walks in Greece. The route descends 16 km from the Omalos plateau at 1,227 metres to the village of Agia Roumeli on the Libyan Sea, passing through the White Mountains National Park on a well-maintained trail through towering limestone cliffs, pine and cypress forest, and the narrow Iron Gates passage. Allow five to seven hours; the gorge is open from May to early October.
Buses depart Hania for the Xyloskalo trailhead at the top in the early morning. At the bottom, boats connect Agia Roumeli with Hora Sfakion for the return bus journey to Hania — there is no road out of Agia Roumeli. The trail can get very busy in July and August; going in May or September gives a significantly better experience. Wear proper walking shoes, bring plenty of water, and start early to avoid both the midday heat and the bottleneck at the Iron Gates.
