Niederbauen-Chulm, Mountain summit in the Urner Alps, Nidwalden and Uri, Switzerland

Niederbauen-Chulm is a 1,923-metre summit in the Urner Alps, on the border between Nidwalden and Uri. It can be climbed from Emmetten in the west or from Seelisberg in the east, where the path passes the Beroldingen manor and the Alp Weid at 1,288 metres before a rock tunnel with a ladder leads to the top.

The summit lies on the cantonal border between Nidwalden and Uri, which runs across the 1,923 m peak. The name Niederbauen refers to the alpine pastureland, and maps also record the peak as Niederbauen Chulm or Niderbauen Chulm; the alternative Niederbauenstock follows the neighbouring, higher Oberbauenstock. The two approach routes start in Emmetten and Seelisberg.

The name Niederbauen refers to the alpine pastureland, while Kulm or Chulm denotes a summit; waymarks sometimes use the spelling Niderbawen. On the Seelisberg route, walkers pass the small castle Schlösschen Beroldingen before reaching Alp Weid at 1288 m. From there a rock tunnel with a ladder leads up to the summit.

A cable car from Emmetten reaches Niederbauen station, with a hiking trail continuing to the summit afterward. The route demands sure-footedness and varies in difficulty depending on the season.

The A2 motorway runs through the Seelisberg Tunnel more than 1,400 metres below the summit, so drivers pass beneath the mountain without seeing it. From the top, the panorama sweeps from Rigi Hochflue and Fronalpstock past Uri Rotstock and Brisen to Stanserhorn and Pilatus above Lake Lucerne.
