The Ferrata della Miniera dell'Erdemolo is a very recent itinerary, realized above the ancient mines of calcopirite (arms) active between 1400 and 1600, in Val dei Mocheni. It is short and in the complex easy, with the only concluding part "moderately difficult": ideal for beginners and for those looking for a first taste of equipped path, between steep path, a short exposed crossing and a vertical wall bracketed with a pinch of overhanging.

Starting from the ' ample paid parking in the locality Frotten («Vròttn» in mòcheno), municipality of Palù del Fersina (TN), reachable by Pergine Valsugana; just before there is also a free parking lot in loc. Canopi, about 20' on foot. Open road signs on Google Maps. From the Frotten parking lot follow the forest road n. 325 towards «Miniera dell'Erdemolo»/Maso Lenzi, reaching in about 30' l' building of mine visits. Continue on the ascent cemented road (indications «Laner – Sette Selle») for about 300 m: on the right a diagonal track (if you reach the sign «343B – Intertol Sette Selle» you have gone over a few meters). This track, uphill south-east in the underwood, leads to all' attack in about 15' (1830 m, about 50' from parking).

The rope begins on a simple slope, followed by easy rocks and an easy crossing. For a large part it is a path equipped with the cord as a handrail, useful on the steep soil mixed with grassy laces and land; a short stretch of rock interrupts the grassy ascent, which continues to bends. A first cambre ladder is easily overcome, then a stretch in the undergrowth and a short and fun across rock in light exposure. Some brackets earn altitudes up to the most beautiful stretch: a traverse on rock and brackets to the left, well exposed for a few meters. The key point remains: a vertical paretine of about 10 m with a short and light strapiombo, however without force on the arms. It stands on a last grassy slope where the cord ends, at 1960 m (40' from' attack, about 1h 30' from parking).

Short path and satisfaction, suitable for those who approach the ferrates. Exposed to the west, you can also face on summer days thanks to the limited direct irradiation. In both ways, unless otherwise indicated.

Summer season; given the low altitude and exposure to the west is pleasant also with moderate heat.

Continue east for a few dozen meters until you enter the trail 324, which takes to the left for the descent (about 20') until the crossroads "loc. Intertol". To return to the forest road and the mine holds the left on 343B; alternatively, on the right on the 324 you reach the Rifugio Sette Selle (about 20') and then descend to the sentiero 343 at the Frotten parking lot, closing a ring (recommended option).

Given the brevity, in the Valsugana area: the easy Ferrata di Valimpach at Caldonazzo, il Sentiero Attrezzato Church in Levico Terme, il Sentiero Attrezzato Bertotti at Passo del Cimirlo and, in the heart of Lagorai, the most challenging Ferrata Gabrielli in Cima d'Asta.
