Named after the Laggin valley and stream on its eastern (Italian) side. Laggin is from a pre-Romance toponym, possibly Lepontic, of obscure meaning.
Rocky, mostly unglaciated four-thousander north of the Weissmies, the last 4000er before the Simplon Pass. Climbed by the west-south-west ridge from the Weissmieshütte.
The Lagginhorn was climbed on 26 August 1856 by the English clergyman E. L. Ames with three Saas-Almagell guides, by what is still the standard route — the broken west-south-west ridge from the Weissmies hut. The summit is mostly broken slate and rubble, which has earned it a reputation as one of the less elegant 4000ers, but it remains a popular pairing with the neighbouring Weissmies.
