Lauchernstock East Ridge Messer – airy ridge climbing above Engelberg

The Lauchernstock East Ridge «Messer» certainly lives up to its name: a narrow rock crest, exposed climbing sections and sweeping views over Engelberg and the Bannalp characterise the tour. The route combines classic ridge climbing with an impressive summit destination.

The climbing is predominantly in the fourth grade; the final summit pitch is graded 5a in the topo. Expansion bolts protect the notable climbing sections. In between, the alpine terrain requires sure-footedness, appropriate rope management and experience on exposed ridges.

The route's character is defined by its narrow line and the alternation between short, steeper sections and easier ridge terrain. The good protection on individual sections does not replace alpine safeguarding techniques at the transitions.

01

Initial upturns

The first pitch is marked as 4c and 20 metres, the second as 4b and 10 metres. In between, the route follows the ridge.

02

The knife

The eponymously named rock edge offers a 45-metre-long passage of grade 4c. Nine bolt anchors are marked for this in the topo. The exposed position makes this section particularly impressive.

03

To the summit

After easier terrain at grade 3a, the 25-metre-long summit pitch follows at 5a. The route remains alpine even after the summit: route-finding to the abseil point and the return journey are part of the overall planning.

Through the cave and back towards Brunni

Descent and abseiling

From the summit, the marked route leads westwards via faint tracks on the north side to the cave abseil point. The topo states this takes approximately 30 minutes. On the map, the location is marked with the Swiss coordinates 677’291 / 189’734 (LV03).

The first abseil pitch leads through the cave. Further abseil sections follow; the topo contains several 25-metre indications. Check the belays and the exact route before each stage.

After the abseiling route, according to the map, the way leads down via Laucheren to the hiking trail and onwards in the direction of Brunni or Ristis. This page thus describes the marked round trip on the Engelberg side.
