Hello dear!
In these hot days I´m still looking for fresh experiences 
The funniest and most adrenalinic way I´ve found to refresh myself is the canyoning.
Canyoning Adventures is the leading company on Lake Garda. They are very professionnal, helping you to have fun without pushing too far the limit.
The company offers several different packages even for kids. I´ve tried the Integral Canyong, that lasts 4 hours, more than 2 in water. You jump, slide in waterfall surrounding by a beautiful nature. Peace and adrenaline at the same time. It was really great!

Have fun
