Adventure activities throughout Italy?

Hi all,

My partner and I are traveling throughout Italy this coming June and are looking at booking some more adventure-orientated activities. So far we have a lot of calm, relaxing plans but are also keen to do something exciting. Things like sky diving, white water rafting - those adrenaline pumping activities.

We are visiting Rome, Amalfi, Sorrento, Naples, Venice and Florence.

Any recommendations and advice would be appreciated!
