Orridi di Uriezzo, Alpine canyon system in Antigorio Valley, Italy.
Orridi di Uriezzo is a system of three main gorges carved into granite, with steep walls rising between 20 and 30 meters high. Water has shaped sinuous passages and rounded cavities through the rock, making the journey through these splits in the landscape a raw geological experience.
The gorges formed approximately 12,000 years ago when the Toce Glacier melted and powerful water currents eroded the granite surfaces. This erosion demonstrates the strength of that meltwater and continues to shape the Antigorio Valley landscape today.
The gorges have long served as walking routes connecting nearby villages, with names that reflect the surrounding landscape and generations of travelers. Today, the paths echo the rural past and show how people navigated this jagged terrain.
Waterproof hiking boots with non-slip soles are essential since the paths stay wet and slippery year-round. The routes can be narrow and overhanging, so moving slowly and paying attention to footing conditions helps you stay safe.
The southern gorge cuts through granite for roughly 200 meters, showing rounded cavities and tunnels in the rock walls. These hollow shapes formed through the action of meltwater over millennia and reveal slow geological processes at work.
