Highlight (Segment) • Trail

This series of hairpin bends, one of the least known yet most beautiful in Valtellina, connect the hamlet of Le Prese to the Val di Rezzalo, passing through the town of Frontale. The view is more panoramic than you think.

Very steep driveway from Bormio to St. Caterina. With the Mtb it is mostly ridable in good physical condition, pushing is sometimes unavoidable if you are not taking the ebike ..

Passo dell'Alpe (2461 m)

Highlight • Mountain Pass

The Passo dell'Alpe (2,461 m.s.l.m.) is one of the most beautiful off-road alpine passes that you will ever do. Reaching it is quite long but feasible with different types of fat-wheeled bicycles. The finish, climbing from Frontale, is steep.

Frequently Asked Questions

What is the overall difficulty and terrain like for this mountain bike loop?

This is a difficult and challenging mountain bike route, best suited for experienced riders with excellent fitness and advanced technical skills. The terrain is diverse and demanding, featuring a mix of asphalt, natural paths, unpaved roads, and paved sections. You'll encounter very steep ascents, particularly from Bormio towards Santa Caterina, where pushing your bike may be necessary if you're not on an e-bike. Expect long single-tracks, technical, narrow, and sometimes exposed paths, with some sections requiring 'portage' (carrying the bike).

What are the best times of year to ride this trail?

The best time to ride this high-altitude mountain bike loop is typically during the summer months, from late June to early September, when the snow has melted and the weather is most stable. Always check local weather and trail conditions before you go, as conditions can change rapidly in the mountains.

Are there any notable landmarks or viewpoints along the route?

Yes, the route offers breathtaking panoramic views and passes several points of interest. You'll experience the wild landscapes of Alta Valtellina and the Stelvio National Park, with stunning vistas of the Ortles group and glimpses of the Forni glacier. Highlights include the Frontale Hairpin Bends Between Le Prese and Val di Rezzalo, the Valtellina Cycle Path, and the charming town of Bormio. You'll also pass the Passo dell'Alpe (2461 m) and the scenic Rezzalo Valley Plateau.

Where can I park to access the trail?

While the Komoot tour starts near Bormio, specific parking details are not provided in the tour data. Given the loop nature and the trail's connection to Bormio, it's advisable to look for parking options in or around Bormio, which is a significant settlement along the route and a common starting point for activities in the area. Public parking lots are generally available in mountain towns.

Does this trail intersect with other well-known paths?

Yes, this route incorporates sections of several other trails. You'll find yourself on parts of the Ciclovia dell'Energia - Percorso Arancio, the Sentiero Valtellina, and the Pedemontana della Reit, among others. These intersections can offer options for extending or modifying your ride.

Are dogs allowed on the trail?

As this trail is located within the Stelvio National Park, dogs are generally allowed but must be kept on a leash to protect wildlife and ensure the safety of other trail users. Always clean up after your pet.

Do I need a permit or is there an entrance fee for this route or the Stelvio National Park?

Generally, there are no specific permits or entrance fees required to access the trails themselves within the Stelvio National Park for day use. However, as a protected area, it's crucial to respect park regulations, which include staying on marked paths, not disturbing wildlife, and carrying out all your waste. If you plan to stay overnight in refuges, reservations and fees will apply.

What kind of wildlife might I see?

The trail traverses the pristine natural environment of the Stelvio National Park, offering opportunities to spot local wildlife. It's common to see alpine animals such as ibex and chamois, especially on the panoramic traverses and in higher altitude sections.

Is this trail suitable for families or beginners?

No, this trail is explicitly rated as 'difficult' and is described as an 'extreme adventure' for mountain bikers. It features significant elevation gain, technical sections, and requires advanced riding skills and excellent fitness. It is not suitable for families, beginners, or casual riders.

Are there any huts or places to stop for refreshments along the way?

Yes, the route passes by a few huts. You'll find Bâite la Mignot and The Val di Rezzalo Hut. These can be good spots for a break or refreshments. Given the length and difficulty, planning stops at these points is recommended, especially if considering an overnight stay.

What should I bring for this mountain bike tour?

Given the trail's difficulty, length, and high-altitude sections, you should bring essential mountain biking gear, including a well-maintained bike, helmet, appropriate clothing layers for varying weather, plenty of water and snacks, a repair kit, first-aid supplies, and navigation tools. Due to potential 'portage' sections, consider a comfortable backpack for carrying your bike if needed.
