White Mountains’ National Park is the only national park in Crete. It centres around the Samariá gorge, at an altitude of 1,200m and continues down to Ayia Rouméli, on the shores of the Mediterranean Sea. Along with the surrounding slopes and a number of smaller gorges branching off from it, Samaria Gorge forms the whole of the area designated as a national park, a status that offers protection to over 450 species of plant and animal, 70 of which are endemic to Crete. In the prefecture of Chania (also written “Hania”), the Samaria gorge is the longest in Europe (total length 16km), and one of the most impressive gorges in Greece. It starts from Xylóskalo, at an altitude of 1,230m. The width of the gorge is 150m at its widest point and 3m at its narrowest.
