The Ponale Trail is the best known and most popular in Garda Trentino: easy but at the same time spectacular as its winds sheer above the lake, a classic trek you can't afford to miss. The line of the Old Ponale Road stands out against the mountainside and is clearly visible from the beaches in Riva and Torbole. The Ponale trail is an icon of Garda Trentino, much loved by visitors and locals alike who never tire of the spectacular views it offers at every bend. The Ponale Road is famous not only for the unequaled panorama of the lake but also for the military installations you can see along the trail. When you come to the second and third tunnels you can see remains of the Tagliata del Ponale, imposing fortifications built by the Austro-Hungarians from 1860 onwards which consist of tunnels excavated into the rock and trenches which stretch from lake level to the outposts overlooking the current trail. Today the Tagliata complex is normally closed to the public for reasons of safety.
