★★★ Via Trenker {UIAA} 5+

After passing the Lokomotiv, go along the southwest wall of the First Tower until you reach a recess, with pillars on the right and left. The route runs along the evident dihedral slightly inclined to the right.

1. Scramble up slightly loose rock to the base of the prominent Trenker Crack. Anchor on pitons, to the left of the crack immediately after the small vertical section. (30m, III)

2. Climb the slightly right-trending crack. Before the crack becomes vertical, traverse 2-3 to the right to a small ledge with the anchor (1 big glue-in bolt). (35 m, IV-)

3. Climb over the easy overhang above the belay, then slightly left to the dihedral. Follow the dihedral, past a steeper polished section protected by a bolt, until you reach a good belay on a ledge. (1 bent glue-in bolt + 2 pitons). (35m, V+)

4. Follow the dihedral up, to the right of the small column, following the slightly polished crack. Continue until the next belay (1 glue-in bolt). (35m, III+) 1 piton.

5. 2 options for this pitch:

a) Head up a couple of metres before leaving the crack and traversing diagonally right up an easy slab to a large ledge. Anchor on two glue-in bolts in the middle of the ledge.

b) Continue up the crack to the top before stepping out right on the ledge, belay on two pitons, OR belay on the right of this directly under the chimney of the final pitch (2 glue-in bolts). (25m, IV-)

1. Traverse another 2-3 meters to the right on the ledge, then follow the yellowish rocks up the chimney to the top. From here, via easy rocks, exit onto the wide ridge that leads to the top of the tower and the anchor (1 glue-in bolt). (30m, IV-) 2 pitons

2. Optional to reach summit: Follow the path to the left to reach the summit of the 1st Sella Tower. (40m, I)

Descent:

a) Abseil from summit: To the right of the saddle between 1st/2nd towers, follow the ridge ~30m to an abseil (40m).

OR

b) Descent by the "Via Normale" From the summit, follow the obvious path that leads to the saddle between the First and Second Sella Towers, then continue around the 2nd Tower, following the rock piles/cairns.

At a crossroads, take the path that turns right down the steep gully towards the valley. There are points where downhill climbing is required, never higher than II.

Here, the abseil and the Via Normale join up again. Shortly before the base of the wall, the trail separates to the left and right. To the right, there are two abseil anchors (top 35m, bottom 25m). To the left there is a downclimb (grade II).

Once at the base, follow the path to the right to return to the parking lot.
