Riserva naturale di Monte Catillo, Regional nature reserve in Tivoli, Italy.

The Riserva naturale di Monte Catillo is a protected woodland area that covers a large portion of the Tivoli mountains and is marked by limestone cliffs, rocky plateaus, and Mediterranean plant life. The landscape shows varied terrain with geological formations that shape the appearance of the terrain.

The area was designated as a protected reserve by the Italian government in 1997 to safeguard the plant life and geological features of the Tivoli region. This official status marked an important step in preserving the natural heritage of the zone.

The reserve's emblem was created by students from the local art school and features a cork oak that represents the plants growing in the region. This symbol connects the artistic traditions of Tivoli to its natural surroundings.

The reserve extends from the north-east edge of Tivoli to the borders of San Polo dei Cavalieri, and its highest point is Monte Catillo, marked by a cross. Paths lead through cork oak woods and open slopes; wear sturdy footwear and carry water, as the terrain is uneven and exposed in places.

The reserve was created largely to protect an unusual cork oak grove growing on limestone rather than acidic soil, far from the coast. The site also shelters Styrax officinalis, the only Italian station of this eastern Mediterranean shrub, plus a protected yellow asphodel and the rare orchid Ophrys tenthredinifera.
