To meet the requests of the many enthusiasts, but also for those who simply want to try a different experience, the Consorzio Frasassi has planned two adventure trails of varying difficulty: the blue trail (which lasts approximately 2 hours) and the red trail (which lasts approximately 3 hours).
Small groups of visitors, accompanied by expert guides, can pass through underground passages, narrow pathways and shafts and admire the splendid rooms concealed from the gaze of "normal" tourists.
All of the equipment needed is provided on site and included in the cost of the trail.
