Top 5 Caves グイドニアモンテセリオでの

Slightly hidden and covered by bush but still interesting to observe along the way

The nature reserve extends over about a thousand hectares between the Tiber Valley and the Cornicolani Mountains, in the Roman Sabina. The landscape is hilly, with pasture areas, crops and fragments of woods, remnants of the original forests. The area is known for its botanical value and for karst phenomena such as caves and sinkholes, including the Pozzo del Merro, one of the deepest in the world. The reserve also preserves historical evidence, from prehistory to the Middle Ages.

A place full of surprises and wonderful views! Challenging due to the climbs and steps but absolutely worth it!

The Pozzo del Merro is a karst sinkhole located in the countryside north of Rome, between the Cornicolani Mountains in Macchia del Barco and Macchia di Gattaceca, in the municipality of Sant'Angelo Romano. According to initial studies by the University of Tor Vergata, the cavity is 392 meters deep, which is the maximum limit the measurements have reached. The probes launched since its discovery have not reached bottom, and the studies continue. This sinkhole has always been known to the locals. In 1890 it appears in the description of a tourist itinerary that leads from Rome to Sant'Angelo Romano, and is described as "a kind of chasm, at the bottom of which extends a small lake and whose very steep sides are covered with trees". https://www.sotterraneidiroma.it/sites/pozzo-del-merro
