The pass is located on the border of the Autonomous Province of Trento (Trentino-Alto Adige region) and the Province of Brescia (Lombardy), on the northern part of the country.

Is the road to Tremalzo Pass unpaved?

Tucked away to the west of the iconic Garda Lake, the road to the summit is totally unpaved. It’s called Strada della Grande Guerra. The road is 10.6 km (6.58 miles) long, running west-east from Rifugio Garda to Rifugio Alpini Passo Nota. It’s a dirt road all the way, quite rough, and, really only suitable for all-terrain/off-roaders such as early Panda 4x4, early Vitara, Jimny, Defender and similar.

Can I drive to to Tremalzo Pass?

The pass is divided into two very different sections: while the northern flank can be traversed legally, the southern flank was closed to all motorized traffic since 2015.

Is Tremalzo Pass open?

The route can be made only during the summer due to the presence of snow. The open and close dates all depend on snowmelt and snowfall each year. 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.

When was the road to Tremalzo Pass built?

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.

Is Tremalzo Pass dangerous?

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 path must be made with caution. With many scenic views of Garda Lake, the average speed is about 5 mph/8 to 10 kph. The pass road has a maximum gradient of 22% through some of the ramps. The drive has a number of shorter rock tunnels.
