GLR 31 Route info

It’s time to head from the great lakes into the High Alpine Region of Italy. Before that, you’re going to explore the lower plains surrounding Turing. All that and more in this GLR 31 motorcycle adventure route! You start your journey in a village near Lake Maggiore called Gravellona Toce. From here, a lengthy on-road section leads you south, away from the mountains. Here you’ll find rice patties, agricultural roads, and irrigation canals. Especially in summer, the temperatures in this region can rise well into 30 degrees celsius. If the temperatures are getting too hot, I would suggest taking the GLR 33 just north of this route. Likewise, when it cools down, this is the ideal route to explore the region! A long 9.5-kilometer on-road section will treat you well after the somewhat longer on-road section. After this, you head eastwards towards Lake Viverone. It’s around this lake where a long string of connected off-road sections will lead you south-east. Again after these off-road sections, a 75-kilometer long on-road section leads you to higher altitudes. Now high in the Alpine region, a 17.4-kilometer off-road mountain pass guides you towards the Susa valley. From here, the last section of this GLR 31 guides you up one of the most famous off-road passes in the region called Colle Delle Finestre. Be aware that this road is closed on Wednesdays and Saturdays, which means that if you want to continue your adventure with the GLR 9 or GLR 30, you’ll need to use the Back-up route section 9 to start at the other side of the mountain. You’ll find the Back-up Route for GLR 31 down below.

GLR 31 Region

With GLR 31 you’re going to explore the regions of Lombardy and Piedmont of Northern Italy. To be more specific, you’ll explore the Como and Varese provinces of Lombardy and the Verbano-Cusio-Ossola, Biella, Novara, Vercelli, and Turin Provinces of Piedmont. Read more about these regions down Below!


Lombardy is one of the twenty regions of Italy. Located in the northwest of the country, it almost counts 10 million inhabitants. Making it Italy’s most populated region. Combined with an on average high GDP, Lombardy is the most populated, richest, and most productive region.

Besides this modern wealth, Lombardy knows a rich historical past as well. The region was called home by two different popes, and it knows the most UNESCO World Heritage sites of the world. But where the real Adventurisers come for is Lombardy’s natural beauty.

The region can be divided into three main natural zones namely the mountains, hills, and plains. All with its distinctive features to please all of your adventure riding needs. In the north, you find the High Alpine region with a predominant Alpine climate above 1500m. More to the south, the lower alps gradually fade away into the plains surrounding Milan.

Lombardy is dotted with numerous lakes. Predominantly in the north, you find most lakes with a glacial origin. Major lakes from east to west are Lake Garda, Lake Idro, Lake Iseo, Lake Como, Lake Lugano, and Lake Maggiore.

For Adventurisers, Lombardy is a beautiful region to explore, but it knows relatively high precipitation in summer. Thunderstorms appear out of nowhere, and hailstorms are a common phenomenon around the major lakes. Please keep an eye out for the weather while in the area!

GLR 30 Region Small Overview
GLR 31 Region Lombardy Map Overview
GLR 31 Region Piedmont Map Overview


The name for this northwestern region of Italy comes from the old Latin and means “ at the foot of the mountains”, and at the foot of the mountains, it is indeed. Almost 45% of the region is mountainous, with the remaining 30% are hills and 25% are plains. Piedmont is the second largest region of Italy, after Sicily.

The region consists of 8 different provinces namely: Cuneo, Turin, Asti, Alessandria, Vercelli, Biella, Novara, Verbano-Cusio-Ossola. Each province has its very distinctive landmarks. Cuneo and Turin are known for their rugged peaks to the west and the plains to the east. As for Vercelli and Novara for its damp rice paddies. 

One of the most remarkable features of Piedmont is that it has almost 60 different national parks. With almost 8% of its entire area marked as a protected area, you would think it’s hard to find sufficient routes to Adventurise. Indeed it is, but Piedmont also houses many of the famous roads among the adventure riding community!

The climate of Piedmont differs as extreme as its geological features. The mountainous area in the west knows an alpine climate where snow can be found at altitude until late in summer. The plains to the east are known for their intense heat in summer and milder temperatures in winter. While Adventurising this region, it’s highly recommended to respect the recommended period given for each GLR. Many of the off-road sections are blocked in winter.

Connections in Colle Delle Finestre

You’ve just conquered the beautiful road up Colle Delle Finestre and you’re looking over the Susa Valley with the old fortifications to your left and the Ligurian Alps to your back. You’re ready for more! Let’s look at your options to continue your motorcycle adventure.

First, take the GLR 29 up north. This GLR will go down the same way you’ve come up. So if you’re not in for some extra off-road kilometers at altitude, I would recommend continuing your journey in Susa, before you head up Colle Delle Finestre. This 303-kilometer long GLR leads you into France and ends near Chamonix. The Alpine capital of Europe.

Or, you take the grand tour of the region with the GLR 30. This adventure route crosses all the major roads in the region like Strada dell’Assietta, Forte Jafferau, and Col del Sommeiller. This is a must-do route in the region, maybe even a must-do in Europe!

At last, I have the GLR 9 as an option for you. This massive 742-kilometer GLR leads you south through the Lunguirian alps and across the border into France. With 233km of off-road sections, this is almost a week-long GLR! Keep this in mind when you want to adventurise the GLR 9.
