Alta Via n. 2 delle Dolomiti: da Croce d'Aune a Rifugio Dal Piaz

The route typically starts from Croce d'Aune. While the provided information doesn't specify exact parking facilities, Croce d'Aune is a known pass, and you would generally find parking available there to begin your ascent.

The route primarily follows an old military road with many hairpin bends. Initially, you'll cycle through wooded areas, which then open up to more exposed, panoramic sections. As you gain altitude, the terrain becomes increasingly stony and rocky, especially in the higher parts. Be aware that some sections might be unmaintained with growing grass, and unstable or protruding rocks can be encountered, potentially requiring you to dismount and push your bike. The descent also demands considerable technical skill due to loose stones.

No, this route is generally rated as 'difficult' for touring cycling. It requires good fitness and advanced riding skills due to its consistent steepness (gradients typically 8-12%) and challenging surface with stony and rocky sections. The 11-kilometer ascent involves a substantial elevation gain, and you might need to push your bike in some parts. E-bikes can make the ascent more manageable for those seeking a less strenuous climb.

The best time to cycle this route is typically during the warmer months when the snow has melted and conditions are more stable. However, be aware that dense fog can occasionally envelop higher altitudes (around 1800 meters), so checking local weather forecasts before your ride is advisable.

The route is located within the Dolomiti Bellunesi National Park. While access to the park itself is generally open, the provided information does not indicate any specific permits or entrance fees required for cycling this particular route. It's always a good idea to check the official park website for the latest regulations if you have concerns.

Beyond the challenging ride, you'll reach Rifugio Dal Piaz, a mountain hut within the Dolomiti Bellunesi National Park. The route also has historical significance for cyclists: it was at Croce d'Aune Pass in 1924 that Tullio Campagnolo was inspired to invent the quick-release mechanism for bicycle wheels. You'll also enjoy spectacular views, especially from Passo delle Vette Grandi, and admire the dramatic hairpin bends and dry stone walls of the old military road.

While the route is primarily a challenging touring cycling path, and dogs are generally allowed in the Dolomiti Bellunesi National Park, it's important to consider the nature of the trail. The stony, rocky, and potentially unmaintained terrain, combined with the demanding ascent and descent, might not be ideal for all dogs, especially if you plan to cycle with them. If you are hiking with a dog, ensure they are well-behaved and kept on a leash, respecting wildlife and other trail users.

The route offers very scenic views, particularly once you emerge from the initial wooded sections. You'll be treated to an enchanting panorama from the Passo delle Vette Grandi, just above Rifugio Dal Piaz. The road itself provides spectacular vistas, showcasing its sinuous curves, dramatic hairpin bends, and cliffs fortified with beautiful dry stone walls. From around 1500 meters, you'll get a picturesque view of the Valbelluna, and the Feltre Peaks within the Dolomiti Bellunesi National Park offer stunning backdrops.

The route leads directly to Rifugio Dal Piaz, which is a mountain hut and would typically offer basic amenities, including food and accommodation. At the starting point, Croce d'Aune, there might be limited facilities, but the primary amenity along the route itself is the rifugio.

Given the 'difficult' rating and challenging terrain, you should pack essentials for a demanding touring cycling trip. This includes appropriate cycling gear, plenty of water and snacks, a repair kit for punctures and minor mechanical issues, a first-aid kit, and layers of clothing suitable for changing mountain weather, as dense fog can occur at higher altitudes. A helmet is essential, and consider gloves for better grip and comfort on the stony sections. Due to the technical descent, good brakes and tires are crucial.
