The canyon was carved by the Tarraios River over several million years through tectonic uplift.
The village of Samaria, located mid-gorge, was named after the 14th-century church of Osia Maria.
The Kri-kri goat, once near extinction, remains the most iconic resident of the park due to strictly enforced conservation efforts.
The park is part of the European E4 long-distance hiking path network.
The walls of the 'Iron Gates' reflect sound so effectively that extreme silence is common despite the geological activity.
Archaeological finds confirm human presence in the gorge dating back to Minoan times, including a temple dedicated to Apollo.
The entire park is designated as a protected area under the Natura 2000 network.
The limestone formations feature significant karstic caves that remain largely unexplored by the public.
Samaria National Park protects a 16-kilometer long canyon in the White Mountains of Crete, functioning as a primary biosphere reserve. The trek begins at the Omalos Plateau at an elevation of 1,250 meters and terminates at the coastal village of Agia Roumeli on the Libyan Sea. The park's narrowest point, known as the 'Iron Gates,' features rock walls rising 500 meters vertically while the canyon width narrows to only 3 meters. The park serves as the primary habitat for the Cretan wild goat, known as the Kri-kri, which is endemic to the island. Geology within the park consists primarily of limestone and dolomite layers dating back to the Triassic and Cretaceous periods. Archaeological remains within the gorge include the deserted village of Samaria, which was inhabited until 1962. Water sources are available at multiple designated springs throughout the trail, though flow rates vary by season. The ecosystem hosts over 450 species of plants and animals, many of which are protected under European environmental directives.

Use sturdy, broken-in hiking boots with ankle support to navigate the uneven, rocky terrain.
Start your trek as early as possible to minimize exposure to midday sun and avoid peak crowd congestion.
Carry only essential gear to reduce pack weight, as the 16km descent is strenuous on the joints.
Attempting the hike without adequate physical preparation or in improper footwear like flip-flops; ignoring weather warnings regarding flash floods.
Open seasonally, typically from May through October, contingent on weather conditions and snowmelt; the park closes during periods of heavy rain to prevent flash flood risks.
Strict 'leave no trace' policy: all trash must be carried out, smoking is prohibited throughout the trail, and picking plants or disturbing wildlife is illegal.
