Wildlife watching

The animals here have never learned to fear the trail.

A century without hunting, fishing, or off-trail human traffic has produced something unusual: wildlife that treats the marked path as background noise rather than a threat. Chamois graze within metres of hikers, ibex bed down on visible ledges in full daylight, and the valley floors carry sound clearly enough that a stag's rutting roar reaches walkers a kilometre away. None of this is staged or baited — it's the by-product of a century of the park's strict no-disturbance rules.

Alpine ibex — around 300 in the park

Ibex favour steep, rocky ground above the treeline, which in practice means the upper reaches of Val Trupchun and the slopes around Il Fuorn. Look for them resting on sunlit rock ledges mid-morning; they're most active at dawn and dusk but visible resting through the day. Males carry the park's most recognisable silhouette — ridged, backward-curving horns that can exceed a metre.

Chamois — the park's most numerous large mammal

The chamois population has held between roughly 1,000 and 1,700 animals since the 1920s, spread across the park's forest edges and open slopes. They're more skittish than ibex but still routinely visible from the trail, especially in Val Trupchun's lower reaches where forest meets meadow.

Red deer — the autumn rut in Val Trupchun

Red deer are the park's headline wildlife event. Through late August, September, and into October, stags gather harems in Val Trupchun's open valley floor and roar to challenge rivals — a sound that carries the length of the valley. This is the single most reliable large-mammal spectacle in the Alps that requires no special permit, blind, or guide: just the right two months and a mid-morning or evening walk up the valley.

Golden eagles and marmots

Golden eagles nest on cliff faces throughout the park and are frequently seen riding thermals above the ridgelines — bring binoculars rather than expecting a close pass. Marmots are common in open meadow around Il Fuorn and along the lower Trupchun trail, and their sharp alarm whistle is often the first sign of a predator (or a hiker) before you spot the animal itself.

Why the wildlife-viewing rules matter here specifically

Every rule on the regulations page — no dogs, no off-trail walking, no drones — exists partly to keep this wildlife undisturbed. A dog on a lead still reads as a predator to a chamois; a drone overhead disrupts eagles far more than a hiker on a marked path ever does. The tameness that makes the park worth visiting is the direct result of the rules that can feel restrictive on paper.
