Day 2

From Asco to Vallone

Today's route starts from Ascu Stagnu station and winds through a dense forest of laricio pines. The landscape soon changes and gives way to a rocky setting as you head towards the Tribulacciu cirque. This section requires constant vigilance, with steep sections secured by chains and ladders to make progress easier. The path then leads to the Argentu lake before reaching the Pointe des Éboulis, perched at 2,604 metres, one of the highest points on the GR20. From here, an imposing panorama unfolds, offering breathtaking views of the emblematic peaks, including Monte Cinto. The rest of the stage descends through a field of unstable rock to Bocca Crucetta, where Lac du Cinto and its firn persist even in summer. The day ends with a long descent to the Tighjettu refuge and then to the peaceful Vallone sheepfolds. This section of the GR20 is renowned for its technical difficulty, confirming the status of this hike as one of the most demanding in Europe.

From Vallone to Vergio

The route begins with a gradual ascent along the Stranciacone ravine, offering a wild, mineral atmosphere. After winding through a forest dotted with imposing granite boulders, you reach the Foggiale pass. From here, you'll have an exceptional view of the Niolu and Melarie valleys. The trail then continues to the Ciottulu di i Mori refuge, at an altitude of 2,000 metres, in an Alpine setting dominated by the impressive silhouette of Paglia Orba (2,525 m), nicknamed the ‘Corsican Matterhorn’ because of its distinctive shape. On the way down, you follow the course of the River Golo, dotted with small waterfalls and pools of crystal-clear water, perfect for a refreshing break. You then arrive at the Radule sheepfolds, where the vast meadows and majestic laricio pines are a reminder of the days of pastoral transhumance. The path crosses a footbridge and plunges into the dense Valdu Niellu forest, a biological reserve rich in biodiversity. This stage ends at the Col de Vergio, surrounded by the imposing peaks of the Parc Naturel Régional de Corse.
