Description
From the Barma Lakes basin, stage four begins with a brief high-altitude stretch before committing to a long descent toward Niel, a Walser hamlet in the municipality of Gaby. The path crosses Col della Vecchia — a smooth rocky ridge marked by a small stone pyramid indicating the border with Piedmont — then drops into a sparse conifer forest where the gradient steepens and the sound of a lateral stream escorts walkers downhill. Niel is a hidden gem: a handful of stone and larch Walser houses, some dating back centuries, clinging to the slope above the Gaby valley floor. La Gruba Relais, the stage's official endpoint, is a small hotel converted from a restored barn offering the most authentic rural hospitality on the entire route. From Gaby a regional bus descends to the main valley, providing an exit option for those who need to interrupt the Alta Via. The stage is short relative to others, but sustained descent demands well-gripping footwear and mindful attention to the knees.

Earth sciences
Geology & landscape
The descent from Barma crosses the eastern slope of Mont Mars, with micaschists and augen gneiss of the Austroalpine basement outcropping along Col della Vecchia. Below 1800 m the substrate is masked by colluvial deposits and Würmian moraines with erratic blocks of gneiss and quartzite. The forested slope toward Niel shows paleosols on decomposed micaschists and fluvial terraces of the Gaby stream. The stone pyramid at Col della Vecchia marks a geological and administrative boundary between Aosta Valley and Piedmont. Eluvial deposits rich in mica and quartz indicate intense chemical weathering on south-facing slopes. Mesozoic limestones of the lower Penninic stack outcrop only in the Gaby valley floor.
History & culture
Niel is one of the most remote Walser settlements in the Gaby valley, with medieval stone and larch houses. La Gruba Relais, a restored barn, symbolises Valdostan rural hospitality.
