The gorge floor at the Iron Gates consists of riverbed stones that require navigation over uneven, slippery terrain.
The vertical cliffs at the narrowest point are so steep they allow only limited direct sunlight to reach the base of the gorge.
The Tarraios River, which flows through the Iron Gates, is seasonal and typically dries up by late summer.
The Iron Gates serve as the primary geological boundary between the upper mountainous sections of the Samaria trail and the lower coastal exit.
The Iron Gates, known locally as Sideroportes, mark the narrowest section of the Samaria Gorge in Crete, Greece. The gorge walls here reach a height of 300 meters while the passage narrows to a width of only 3 to 4 meters. This geological feature is the final major bottleneck for hikers traversing the 16-kilometer Samaria National Park trail toward the Libyan Sea. The passage is formed by the erosion of limestone cliffs by the Tarraios River. Due to potential rockfall hazards, the path through the gorge is strictly monitored by park authorities. The site is situated near the exit of the gorge, approximately 3 kilometers before reaching the village of Agia Roumeli. Access is exclusively by foot through the protected national park.
From the center of the narrowest passage, looking upward toward the sky between the vertical limestone cliffs.
Wear high-traction hiking boots with ankle support to navigate the loose rocks and riverbed stones safely.
Carry at least two liters of water, as there are no natural sources between the park entrance and this point.
Check park weather alerts before entering, as rain in the mountains can trigger dangerous flash floods at the narrow passage.
Attempting the hike in standard sandals or flip-flops; ignoring warning signs regarding rockfall risks.
The gorge is typically open from May through October, depending on weather conditions and snowmelt levels; it is closed during winter months.
Stay on the designated path, do not climb the rock walls, and carry out all trash to preserve the protected national park status.
