This experience lasts about 4 hours, where along its approximately 700 metres of extension we will go over several natural obstacles, such as cliffs or confined spaces, where we will have to make several descents in rappel that vary between 10 and 30 metres, walk along little-known trails, climb using the handrail climbing technique with about 100 metres in length, cross confined areas (grotto) or even climb a rocky wall in the style of Via Ferrata. Enough arguments to challenge the most daring adventurers, if we're lucky we'll get to see some bats! adventure yourself Accessible from 10 years old.
