The boundary between the cantons of Bern and Lucerne runs in a north-south direction through the Napf Region, past the summit hotel that lies on Bernese territory. The Napf summit has panorama views over rural Canton Lucerne and the Bernese Emmental. At night, the lights of the Jungfraujoch, the Stockhorn peak and the Jura Weissenstein are visible.

The Napf mountain consists mainly of conglomerate rock. It is a steep ridge formation created from millennia of alluvial deposits by the nascent Aare River on its path down to the Swiss Mitteland. This movement also brought gold down from the Alps; minute slivers can still be panned in most streams. During the World Wars, coal was mined in the Napf Region.

There is no road or railway access to the Napf peak. Short hikes to the peak start at Mettlenalp at the far end of the Fankhausgraben (via Trubschachen) and at Hinder Ey at Luthernbad. One of the most popular Emmental hikes with beautiful scenery is the trail from Lüderenalp to the Napf. Traditional inns along the way offer refreshment. The Berghotel Napf at the summit has a sunny terrace and basic rooms as well as dormitory accommodation, making it ideal for families with children.

Several other interesting hiking and mountain biking trails criss-cross the Napf Region. The Napfbergerland border trail is 85 kilometres long and leads through wild and romantic terrain from the baroque monastery of St. Urban over the Napf to the Brienzer Rothorn peak. This long distance trail follows the culturally and historically important boundary between the cantons of Bern and Lucerne. The forests around the Napf are a natural habitat of wood grouse. Hikers should take care not to disturb them.
