Samaria Gorge

The Samaria Gorge is the longest gorge in Europe — a 16 km cut through the limestone of southwestern Crete that opens onto the Libyan Sea. The walls rise more than 1,000 m on both sides; at the Iron Gates near the southern end, the gorge narrows to just three metres across with sheer cliffs on each side. Protected as a Greek national park since 1962, the gorge is also one of the last refuges of the kri-kri, the wild Cretan goat, descended from prehistoric livestock and only found here and on three offshore islets.

The hike is one-way and entirely downhill: starting at Xyloskalo (1,230 m) on the Omalos Plateau, it descends through cypress and pine to the floor of the gorge, passes the abandoned village of Samaria — evacuated when the park was created — and continues to the Iron Gates and onward to the coast at Agia Roumeli, a small ferry village with tavernas, a black-sand beach, and no road access. The first 3 km are the hardest, a steep "Xyloskalo" zigzag down wooden steps that gives the trailhead its name. After that the gradient eases. Cumulative descent is roughly 1,200 m and many hikers find the second half (broad gravel riverbed in the sun) more tiring than the first. Hikes take 5–7 hours including stops.

The park is open May 1 to mid-October (occasionally weather-dependent into late October). Outside that window the gorge is closed and dangerous — flash floods are real in winter. There's an entrance fee at the gate (€5), no permit lottery, no guide required. Carry plenty of water though springs along the route are reliable. The most important logistical detail is the ferry: only one or two boats a day leave Agia Roumeli, eastward to Chora Sfakion or westward to Sougia, and they connect with afternoon buses back to Chania. Most visitors do the gorge as a day trip from Chania through an organised coach-and-ferry package, but independent hikers manage easily with the public bus schedule.
