The Aniene River Park is one of the most interesting destinations to explore by bike in Rome. Along the river, trails accessible to all wind: from flat and relaxing stretches, perfect for city bikes or trekking, to more technical dirt trails, ideal for those who want to have fun with a mountain bike or enduro bike. Pedaling among willow trees, small bridges, and natural views, you'll forget you're in the city: the noise of traffic gives way to the rustling of the wind and the slow-flowing water. A place where every cyclist can find their own pace—from a leisurely ride to a short off-road adventure—surrounded by the greenery and history of Rome.

Suggestive to say the least, very low grass and populated by cows and horses. An excellent refreshment point before the summit!

Strada Bianca connecting via della Cesarina and via di Casal Boccone. The first stretch is a dirt road up to the bridge that crosses the ring road; then continues on a beaten path between cultivated fields. It ends with an easy singletrack up to Via Casal Boccone skirting the Almaviva building.
