Napf, Mountain summit at the border of Bern and Lucerne, Switzerland

Napf is a mountain summit located at the border between Bern and Lucerne, made of conglomerate rock and rising to about 1408 meters. The slopes are covered with dense spruce and fir forests that open up only at the scattered farms, where meadows are kept clear for grazing.

The Napf lies on the Brünig-Napf-Reuss line, a boundary between Swiss dialect and settlement regions that runs from the Brünig Pass over the Napf to the Reuss. The summit itself sits on the cantonal border: the mountain restaurant stands in the municipality of Trub in Bern, and the Lucerne border runs just a little north of it.

The Brünig-Napf-Reuss line crosses the summit, a boundary between Swiss dialect regions. The nearby Napf Hotel and its viewing platform serve hikers on the Alpenpanorama-Weg and Grenzpfad Napfbergland routes. The name Napf, meaning a small bowl, refers to the rounded summit shape.

Trailheads for the summit are the Mettlenalp (1052 m) to the south and Luthern (772 m), Luthern Bad (875 m) and Wiggernhütte to the north. Two SchweizMobil routes cross the mountain: route 3, Alpenpanorama-Weg (stage 15, Napf–Lüderenalp), and route 65, Grenzpfad Napfbergland. The summit restaurant stands in the canton of Bern, in the municipality of Trub, just south of the Lucerne border.

The summit lies just south of the border with the canton of Lucerne, while the mountain restaurant on top stands in the municipality of Trub in the canton of Bern. The ridge runs west to east from the Farnli-Esel over the Hochänzi and the Napf to the Hängst.
