The Nera Cycle Route, in the section from Sant’Anatolia di Narco to the Marmore Waterfall, forms part of the wider and more demanding Greenway del Nera loop and connects the former Spoleto–Norcia railway with the lower Valnerina and its villages, running for long stretches also alongside the Via di Francesco.

The itinerary extends for just over 28 kilometres, alternating between asphalt and gravel surfaces, and always following secondary roads with limited vehicular traffic. The route does not present particularly demanding climbs, but rather a succession of short ups and downs, sometimes steep; the most significant ascent is approximately 1 kilometre long and leads from the valley floor to the historic centre of Sant’Anatolia di Narco.

The route follows the course of the Nera River, constantly immersed in woodland and cultivated fields, offering a particularly pleasant and often shaded ride. In this stretch of the Valnerina, several villages are perched on the surrounding hills. True gems of the area include Sant’Anatolia di Narco, Scheggino, Ceselli, Ferentillo, Arrone and Casteldilago, all of which deserve a short visit to their historic centres, perhaps combined with a taste of the excellent local food and wine.

Ferentillo, a picturesque village dominated by two fortresses, is home to the fascinating Museum of Mummies and a well-known climbing crag located just outside the town.

The final kilometres of the route develop through scenic woodland sections; after crossing a small bridge, the itinerary continues towards the Lower Belvedere, at the foot of the impressive Marmore Waterfall, which marks the end of this evocative cycle route in the heart of the Valnerina.
