Riserva naturale guidata Calanchi di Atri, Regional nature reserve in Atri, Italy.

Riserva naturale guidata Calanchi di Atri is a protected area of about 380 hectares lying entirely within the municipality of Atri, in the province of Teramo. Its bare clay slopes are cut into furrows and narrow ridges by water erosion, while the reserve also takes in the Piomba torrent and several small ponds. It was established in 1995 and is now managed by the WWF through a cooperative.

The reserve was established in 1995 as a guided nature reserve within the municipality of Atri, in the province of Teramo. Management was later transferred to the WWF through a cooperative. It protects about 380 hectares of calanchi, the eroded clay gullies that give the area its name.

The reserve is managed by the WWF through a cooperative, which took over its running recently. Its name comes from the calanchi, the eroded clay gullies that give the landscape its shape, and the reserve extends well beyond them into willow and white poplar stands. Visitors can look for wild gladiolus, capers and licorice growing on the bare-looking slopes.

The reserve is accessible by marked trails from the town of Atri, located about 7 kilometers from the A14 Adriatica highway exit at Atri-Pineto. Sturdy footwear is recommended since the eroded terrain can be uneven and slippery underfoot.

The reserve extends well beyond the calanchi themselves, and near the Piomba stream and several small ponds live foxes, badgers, porcupines and the hazel dormouse, alongside the emerald toad, a rarer amphibian. The Piomba also makes the reserve a resting point for migratory birds.
