Caffarella: follow the story of water
The Sentiero dell’Acqua leaflet is a menu of linked places rather than a single compulsory circuit. Start from an entrance that suits you and use its map to connect a selection of springs, the Almone, the Ninfeo di Egeria, cisterns and old agricultural buildings. The official allowance of 3–4 hours is for exploring the whole valley on foot, with time depending on pace and stops; no fixed distance is given. For a shorter outing, choose a few nearby stops and return the same way. The thread connecting them is water: it irrigated crops and later powered mills and cloth-working machinery.
Dirt paths and valley slopes require care. The park identifies rough ground near Egeria and Vaccareccia, and a 10% slope between the Appia-side approach and the birdwatching hide. Ask for an entrance-specific plan if you use wheels or walking aids.
