The bridge is not man-made but a natural rock formation carved by constant water flow through limestone strata.
The gorge is known for its high biodiversity, serving as a micro-habitat for amphibians and specific fern species that thrive in the canyon's moisture.
The location is situated just kilometers away from the Sanctuary of Hippolytus, bridging the gap between local geological landmarks and archaeological history.
The canyon walls reach heights of several meters, creating a natural acoustic chamber that amplifies the sound of the flowing stream.
Devil's Bridge (Diavologefyro) is a natural limestone arch formed by the erosion of the Gefyri River gorge near the ancient site of Troizina. The bridge spans a narrow, deep canyon with vertical walls characterized by lush, endemic vegetation and running water throughout much of the year. It is located in a seismically active region known for its unique geological formations that combine Mediterranean maquis with dense riparian flora. The site is part of the broader Troizinia archaeological and natural landscape, historically linked to the myths of Theseus. Visitors can traverse the narrow trail leading into the gorge floor to view the arch from beneath. The environment is humid and shaded, contrasting significantly with the dry, sun-exposed hills of the surrounding Argolis peninsula.

Wear hiking boots with high-traction soles, as the rocky terrain near the stream is consistently slippery.
Bring insect repellent, as the humid, shaded gorge environment is a frequent habitat for mosquitoes and gnats.
Check local weather forecasts beforehand; heavy rain can cause rapid water level increases in the narrow canyon.
Do not attempt to hike into the gorge during or immediately after heavy rainfall due to flash flood risks.
Practice 'leave no trace' principles; the area is ecologically fragile and lacks waste management facilities.
