So I didn't get a chance to sail there but we stopped by on our way from the Dolomites to Bologna. I was going to sneak in a hour or two of sailing while my family hung out but I had a nasty eye infection at the time.
Lots of windsurfers, way more than kiteboarders. You can see all the small sails in the distance. We were at the north end by Torbole. In some ways it reminded my of Squamish with the thermal wind and rock wall on the western side. Lots of people with mountain bikes, too.
