Stage two of High Route 1 begins with a brief descent from Perloz toward Lillianes before committing to a long, sustained climb into the Regional Nature Reserve of Mont Mars. The path winds upward through mixed woodland — birch, larch and Scots pine — where road noise fades quickly and the sound of side-streams takes over. As altitude accumulates the forest opens onto high pastures scattered with emerald glacial tarns, the celebrated Mont Mars lakes that have drawn pilgrims and walkers for centuries. Rifugio Coda, at 2280 metres in the heart of the reserve, is run by the CAI section of Pont-Saint-Martin and offers a genuine mountain-hut experience well away from mainstream tourism. Every year in early July the surrounding meadows host the traditional alpine procession of Mont Mars, a ceremony weaving together religious devotion and the pastoral memory of Walser communities. The stage involves no technical difficulty but demands steady, unrelenting ascent: an early departure allows walkers to enjoy the raking morning light on the eastern peaks and to arrive at the hut with comfortable time to spare before evening.

Along the route: from Perloz (1148 m), the path passes Lillianes (565 m) — Brief descent to valley floor, springs near the stream; Mont Mars (2600 m) — Panoramic ridge with emerald glacial tarns, to Rifugio Coda (2280 m). Along the way you reach the Coda refuge, a useful base. The skyline is dominated by Mont Mars (2600 m), Mont Nery (3075 m), Monte Rosa (4634 m).

Earth sciences

Geology & landscape

The Mont Mars slope belongs to the Austroalpine domain, with outcrops of augen gneiss and garnet micaschists typical of the Sesia-Lanzo metamorphic basement. Glacial tarns on the summer pastures occupy cirques carved by the Würm glacier, with well-preserved lateral moraines and proglacial sand-gravel deposits. Above 1800 m, quartzites and mica phyllites appear with bands of quartz-feldspar pegmatites. Alpine bogs along the trail indicate post-glacial lacustrine deposits on impermeable substrate. Penninic ophiolites (serpentinites and basalts) are visible only distantly toward the Lys valley. Differential erosion has cut deep gorges in micaschists, with erratic gneiss boulders on terminal moraines.

History & culture

The Mont Mars Regional Nature Reserve protects alpine ecosystems and glacial lakes. In early July the Mont Mars alpine procession takes place, blending devotion and Walser pastoral memory.
