Red-earth pinnacles and gullies known as the 'Grand Canyon of the Marche'
The Lame Rosse, the 'red blades', are an extraordinary natural formation hidden in the Monti Sibillini, above the turquoise reservoir of Lago di Fiastra in the Macerata province of the Marche. Erosion of a soft bank of red clay and calcareous gravel has carved a cluster of pinnacles, towers, and gullies stained ochre and rust by iron oxide, an unexpected sight in the green Apennines that has earned the spot the nickname of the Grand Canyon of the Marche. The formation is reached by a pleasant and easy-to-moderate walk of around three kilometres each way from the car park near the Fiastra dam, climbing gently through woodland and along the lakeshore with a modest height gain of a few hundred metres; the round trip takes about three hours at a relaxed pace. The trail is free, though seasonal parking near the dam is paid and fills early on summer mornings, so an early start is wise. There is little shade near the formations themselves, so a hat, sun protection, and plenty of water are essential in warm weather, and sturdy shoes help on the gravelly final approach. The walk combines naturally with a swim or a picnic at Lago di Fiastra, and with visits to the medieval villages and sanctuaries scattered through the Sibillini foothills. Spring and autumn offer the most comfortable temperatures and the clearest light on the red rock, while summer brings the option of cooling off in the lake afterwards. The area lies within the zone affected by the 2016 central Italy earthquakes, and some nearby villages are still recovering, so visitors should check the condition of roads and facilities before setting out.
