Sailing
The whole lake is good for sailing, but the stronger winds are in the north side, where the mountains sorrounding the lake are every mile nearest each other. Sort of Venturi effect.
So, if you are a windsurfer (or kite surfer), the best places are North of Malcesine (Verona Province) to Torbole (Trento province) and Campione del Garda (Brescia province, just below a vertical cliff).
All the rest may do if you sail something that floats even if slow....
