I went wakeboarding in Lake Caldonazzo... it was a really fun experience, but not the best wakeboarding. I found a waterskiing club, and they had a closed bow Ski Nautique with no backseat, much less any ballast, so I wasn't able to go big or anything. I think it ended up costing around $50 US equivalent for a quick session, but I don't really remember. This was like 5 years ago.
I don't know anything about cable parks out there. But I second how Germany is supposed to have a lot.
I will actually want to keep checking up on this because I'm going to Florence all of July!!! So hopefully I'll be able to go wakin again
Keep the info coming
