La Fenêtre du Tsan, at 2736m, is a natural balcony that opens between the crests of Valtournenche and Valpelline, offering spectacular views of the Becca di Luseney and the Crottes towers. The hike, immersed in mountain pastures, streams and larch woods, culminates in this pass where a stone cairn marks the passage to a breathtaking panorama. An intense stage, suspended between sky and rocks, capable of giving emotions even at high altitude.

Lake Tzan, nestled in the valley of the same name in Valtournenche at over 2,440m above sea level, enchants with its green and transparent waters. The path that leads to it is a journey through larch forests, silent mountain pastures and unexpected panoramas, culminating in an alpine oasis suspended between the sky and the rocks. Here you will find the silence of high altitude, broken only by the gentle lapping of the lake, while the surrounding peaks such as Punta Tzan and Dôme de Tzan act as silent guardians. A perfect place for those seeking an immersive mountain experience, enriched by the bivouac next to the shores and a peace that remains in the heart.
