Orrido di Botri, Nature reserve in Province of Lucca, Italy

Orrido di Botri is a nature reserve in the Province of Lucca featuring a deep limestone canyon with vertical walls sculpted by water erosion. The reserve contains multiple caves and narrow passages that wind through the gorge where shallow streams flow.

The Orrido di Botri became a state nature reserve in 1971, covering 192 hectares in the province of Lucca. The gorge itself was cut by the Rio Pelago through limestone below the Tre Potenze and Monte Rondinaio. The Reparto Carabinieri Forestali di Lucca now issues permits and patrols the reserve.

Access to the gorge runs through the dry bed of the Rio Pelago from Ponte a Gaio, and the Lucca Carabinieri Forestali unit issues the permits and patrols the reserve. Because the route follows the torrent bed, entry is allowed only from mid-June to September.

The reserve is best visited during warmer months when water levels are lower and paths are safer to navigate. The terrain is rocky and requires sturdy footwear, as well as willingness to wade through shallow streams.

Access to the gorge is only permitted from mid-June to September, when the Rio Pelago's bed is dry enough to walk through from Ponte a Gaio. Permits and checks are handled by the Carabinieri Forestali unit of Lucca, so visitors pass through a controlled route rather than open terrain.
