Passo del Tremalzo, is a high mountain pass at an elevation of 1.702m (5,584ft) above the sea level, located in the province of Trento in Italy. The pass lies near Trento and Lake Garda and the road over the pass was built for strategic reasons during World War I.
Due to the unique location it is important when driving in these conditions to be prepared. In summer the climate becomes milder thanks to the influence of Lake Garda, while in winter it snows a lot and the thick blanket of snow lasts from November until April because of its exposure to the north-west. During the WWI, Italian soldiers occupied the southern side of the valley, placing their headquarters at this pass. The Austrians were on the northern side where they had already dug out several trenches and prepared artillery. The Italian troops did not have enough time to excavate the rock to make shelters and attack points but they transformed the old paths linking the valley to the most important mountains areas into cart tracks to allow a faster transit of the artillery. The most important of these works regarded the road to Tremalzo.
Due to frequent rock slides, the old spectacular road is more and more in danger. Rocks fallen on are not removed and sections of road broken away not renewed. The route clockwise, after a slight climb, begins a 10 km long climb that takes you from an altitude of 600 meters to 2000 meters (Tremalzo pass), following a beautiful descent on a military road in the 1st World War, even a small uphill and then take a downhill to the point of departure.
The path must be made with caution. With many scenic views of GardaLake, the route can be made only during the summer due to the presence of snow. The south side of the pass requires an all-terrain vehicle.
The pass road has a maximum grade of 14%. Starting from Storo, the scent is 21.7 km long. Over this distance, the elevation gain is 1.277 meters. The average percentage is 5.9 %.
