This trail is considered a moderate hike. While it doesn't present significant technical difficulties, it requires a minimum level of training and is suitable for older children. Expect an elevation gain of approximately 790 meters, with some sections being quite steep.
The route offers diverse terrain, starting with larch forests in the initial ascent from Glacier. It then opens up, passing through the "Conca delle Acque Bianche" with its milky-white glacial waters. You'll encounter both dirt roads and more narrow, sometimes steep, sections, including rocky canalinos, as you ascend into the high Alpine environment.
Key highlights include the stunning views from Col Cornet (2,354 m), the beautiful hidden Lago Cornet nestled in a rock basin, and the unique Conca delle Acque Bianche. You'll also cross the Gaula Stream. From certain vantage points, you can enjoy wide-ranging views of surrounding peaks like Mont Gelé and the Grand Combin.
The trail is generally dog-friendly, allowing you to bring your canine companion. However, always ensure your dog is kept on a leash, especially in areas with wildlife or other hikers, and be mindful of the rocky and steep sections.
The best time to hike this Alpine trail is typically during the warmer months, from late spring to early autumn (June to September), when the snow has melted and the weather is more stable. This period offers the most pleasant conditions for enjoying the high Alpine environment and vistas.
While specific parking details are not provided, trails in the Aosta Valley often have designated parking areas near the starting points of popular routes, such as in the village of Glacier in the Ollomont valley.
