The arch is a remnant of a prehistoric grotto that collapsed, leaving only this limestone bridge behind.
It is composed of Cretaceous limestone, a common rock type found throughout the island of Capri.
The structure serves as a natural window, framing views of the Sorrentine Peninsula and the sea.
The geological process that created this arch involves both marine erosion at the base and wind erosion at the summit.
The Natural Arch (Arco Naturale) on the island of Capri is a remnant of a collapsed grotto dating back to the Paleolithic era. It is a limestone formation shaped like a horseshoe that stands approximately 12 meters high and spans 18 meters in width. The arch is situated on the eastern coast of the island, overlooking the Mediterranean Sea. It is formed by the erosion of sedimentary rock that once belonged to a massive coastal cave system. A network of steep paths connects the arch to other coastal viewpoints. The surrounding terrain consists of jagged cliffs and Mediterranean scrubland. It is a protected geological feature accessible only by foot. The formation is a classic example of karst topography occurring in a marine environment.
Position yourself at the primary observation point directly in front of the arch to capture the frame of the sea and the Faraglioni rocks in the distance.
Wear sturdy hiking shoes as the path involves uneven terrain and steep stone steps.
Carry sufficient water, as there are limited services once you begin the ascent.
Combine your visit with the coastal path that leads toward the Grotta di Matermania.
Attempting the walk in formal footwear or flip-flops, and expecting vehicle access directly to the arch.
Respect the natural site by staying on marked paths and refrain from climbing on or tagging the rock formation.
