Ferrata Ponza Grande

Overview

This route describes the ascent of Ponza Grande in the Julian Alps, starting from the area of the Laghi di Fusine in the province of Udine. It is a via ferrata of medium technical difficulty, but one that demands attention for several exposed passages, particularly along the summit ridge and in the descent gully. The reward is an exceptional 360-degree panorama over the main peaks of the group, on both the Italian and Slovenian sides.

Approach

Access begins from the parking area at the Laghi di Fusine, reached by turning right at Fusine Valromana, a village near Tarvisio. From here, take trail 512, well-marked and leading to the Rifugio Zacchi. The initially wide track soon becomes a forest path that, with an elevation gain of about 400 meters, reaches the refuge at 1380 m in roughly 1 hour and 15 minutes.

From the refuge, a hub of trails, follow the signs for Ponza Grande and Forca Rossa, heading east. Once out of the tree cover, the route develops across scree fields and among dwarf pines, featuring a few short, easy equipped sections, mainly to facilitate passage over rocky outcrops. Continuing by following paint marks on the rock, you approach the west face of the mountain: here the trail becomes steep, exposed, and unprotected, requiring a steady foot. A large red paint mark signals a fork: left for Ponza Grande, right for Ponza di Mezzo. Taking the left, you find yourself facing the imposing rock wall that hosts the start. After crossing a debris chute and another short equipped section, the trail narrows and gains height quickly. A final stretch disturbed by a landslide precedes the arrival at the red mark indicating the start of the ferrata. The total approach time from the parking lot is about 2 hours and 45 minutes.

The environment transforms progressively: from dense forest to open scree slopes, until you confront the severe architecture of the wall. The climb is continuous and physically demanding, with a sustained pace that prepares you for the vertical effort ahead.

Via Ferrata

The actual ascent begins by overcoming a small vertical slab to bypass a spur. The rock is generally excellent, compact and rewarding, except for a couple of points. Rocky steps and traversing sections alternate until you reach a solid, if dated, metal ladder. Turning around, you can glimpse the distant profile of Mangart through Forcella Planiza, a useful reference for orientation on the descent. A ledge follows, rounding a corner and leading into a debris-filled gully. This gully is climbed free, without the aid of fixed ropes, until you emerge onto the ridge and reach the summit of Ponza Grande at 2274 meters. The duration of the ferrata is about 1 hour and 15 minutes, for a total of 4 hours from the start.

The route unfolds on an articulated face, alternating short overhangs with long horizontal ledges that allow you to admire the panorama. The pace is uneven: technical vertical sections follow more relaxed stretches of progression, with constant exposure that never becomes overwhelming thanks to the solidity of the rock. The exit onto the crest gives a feeling of wide-open space after the relative confinement of the gully.

Descent

From the summit, the white-red trail markers initially lead a few meters onto the Slovenian side, just below the crest line: this passage is quite exposed and only partially equipped. After a brief loss of elevation, you return to the ridge, narrow and adrenaline-filled, then descend to a saddle. Here, take the trail to the right that brings you back into Italian territory and, through a steep descent with some exposed traverses, leads back to the Rifugio Zacchi. From the refuge, retrace the approach trail back to the parking lot. The descent from the summit takes about 2 hours and 30 minutes, for a total hike of 6 hours and 30 minutes.

The descent has a different character from the ascent: less technical but more psychological, with continuous exposure on airy and unstable terrain. The pace is slow and deliberate, requiring constant attention. The trail winds along a sharp ridge, offering a pure high-mountain experience.

An alternative return option has existed since 2022, with the renovation of the historic Ferrata Kugy on Strugova. This choice, however, involves traversing the ridge that connects the Ponze with Strugova, a far from trivial route that requires great experience and a steady foot. The few metal fixtures present along this crest are often in poor condition and do not offer real security. Once at the summit of Strugova, descend the ferrata and from a scree slope at its base return to the Rifugio Zacchi.

Useful Notes

The Julian Alps offer an austere and thrilling environment, and Ponza Grande is a worthy representative. The ridge towards Mangart is spectacular but very exposed, with sometimes precarious equipment: it is not recommended for those without solid experience. Caution during the approach when crossing the chutes, which at the start of the season may hold residual snow, increasing the risk of instability. The via ferrata has historical origins, having been built by the Alpini in the 1920s for border control, and it constituted one of the accesses to the famous "Strada degli Alpini." The route thus combines notable mountaineering interest with historical significance, in a panoramic context of great impact.
