Corno Segnà 2668 m


Corno Segnà 2668 m is a minor peak, anyhow interesting and very well identified, belonging to the South-Eastern sector of the Presanella Group, and culminating in a tiny summit surrounded by beautiful granite peaks, amongst those the same Presanella main summit. Corno Segnà is lying immediately to the right of Cima Pellissier, just unmistakable in reason of its East wall fully engraved by a wide dihedral, summit that therefore is useful as a reference to locate Corno Segnà, equally attractive but less flashy. Both the peaks overlook the basin of the magnificent Laghi di Cornisello. Also Corno Segnà is engraved in the upper part of its length by an obvious dihedral, giving the line of one of the most frequented climbing route, Diedro dell'Ideale (Ideal Corner).

Il Corno Segnà 2668 m è cima minore ma molto ben identificata, appartenente al settore sud-orientale del Gruppo della Presanella. Culmina con una minuscola vetta circondata da splendide montagne di granito, tra cui la stessa vetta principale della Presanella. Il Corno Segnà è situato immediatamente a destra di Cima Pellissier, inconfondibile in quanto la sua parete Est è interamente incisa da un ampio diedro, che è quindi utile come riferimento per localizzare il Corno Segnà, ugualmente attraente ma meno appariscente.
Entrambe le cime si affacciano sul bacino dei magnifici Laghi di Cornisello. Anche la parete Est del Corno Segnà è inciso nella parte superiore da un evidente diedro, che costituisce la linea di una delle vie di arrampicata più frequentate, il Diedro dell'Ideale.

Getting There

Road access The road access is from Val Rendena, where a turn-off road allows to reach by car up to more than 2000 m of altitude.  

Getting to Val Rendena Coming from Autobrennero exit Trento and take the road to Riva del Garda, reaching the village Le Sarche. Here continue straight toward Tione di Trento. In Tione turn to right and take the SS 239 Val Rendena route to Pinzolo. Pass Pinzolo and drive a few kilometers towards Madonna di Campiglio. After the village of Carisolo, leave the main road and turn to left, taking a narrow road rising along the Val Nambrone towards Laghi di Cornisello. After driving about 9 km on this road with several hairpins we reach a fork.

The left road leads to Val d’Amola, we instead keep the main road (Laghi di Cornisello) side and continue driving for about 4 km, reaching a parking lot near Rifugio Cornisello (a minute above the parking) and Laghi di Cornisello, situated beyond the bridge along a gravel road (cars not allowed).

Pleasant trad route not too demanding, which follows an obvious corner cutting the East face of the peak. The rock is the characteristic kind of granite named "tonalite", of good quality, and the route is advisable and located in an alpine setting of great beauty.Approach - From the car park cross the bridge and walk along the gravel road skirting the Cornisello lakes; arrived near the Malga Cornisello leave the road and take to the right the path SAT 239 towards Lago della Vedretta (signpost). After about 15 minutes of ascent leave this path and go left, rising without a trace the grassy slopes on the left. After reaching the summit of the hill traverse slightly downhill to the left, heading for the wall cut from the large open dihedral now well in sight. Cross towards the left a slightly ascending slope of big blocks, heading to the left one of two parallel dihedral at the base of the wall. Attack on a nice well carved wall to the left of the dihedral (hole with rope lanyard). Cairn.
