Forra del Rio Secco is a limestone canyon-drop and narrow ravine above Lake Tenno (Lago di Tenno). Photographers come for dramatic rock textures, moody shade, and potential river mist reflections when water flow is active. Best light is late afternoon through early evening; weekdays reduce trail traffic. Parking is limited—arrive early and follow marked paths; no special permits typically required.
