Sighiștel, Brook and slot canyon in Câmpani, Romania

Sighiștel is a brook and slot canyon located in Câmpani, in northwestern Romania, within the Apuseni Natural Park. The canyon walls rise steeply and close in on either side, narrowing at some points to just a few feet (roughly 2 meters) apart, forming a dark, winding passage through which the brook flows.

The slot canyon was formed by the slow erosion of water cutting through soft limestone over thousands of years. The distinct rock layers visible on the walls show how the land changed over that long span of time.

Sighiștel is the name shared by both the brook and the slot canyon it has carved over centuries. Hikers who walk the marked trail through the gorge often describe the sensation of moving through a long, rocky corridor where daylight enters only from above.

The trail through the canyon is marked with blue triangles and is suited for walkers with a moderate level of fitness. Sturdy footwear is strongly recommended, as the rocks can be wet and slippery, especially after rain.

At the narrowest point of the gorge lies a section called Cheia Rea, where the walls press so close together that no direct sunlight reaches the ground below. Moss covers the damp rock surfaces, giving the stone a faint greenish tint throughout the passage.
