The Lötschberg is an Alpine mountain massif, usually associated with a major, historically important transit axis of the Alps in Switzerland with, at its core, the Lötschen Pass. The mountain pass, which culminates at nearly 2,700 metres above sea level, are part of the eastern Bernese Alps, whose main crest straddles the border between the cantons of Bern and Valais. The valleys concerned by the Lötschberg are those of the Kander in the Berner Oberland, with Kandersteg at the head of it, and a secluded side-valley of the Upper Valais, the Lötschental, with Ferden at the valley's entrance and at the bottom of the pass.

The Bernese Alps are a mountain range of the Alps, located in western Switzerland. Although the name suggests that they are located in the Berner Oberland region of the canton of Bern, portions of the Bernese Alps are in the adjacent cantons of Valais, Fribourg and Vaud, the latter being usually named Fribourg Alps and Vaud Alps respectively. The highest mountain in the range, the Finsteraarhorn, is also the highest point in the canton of Bern.
