Brisi, Alpine summit in canton St. Gallen, Switzerland.

Brisi is a summit of the Churfirsten group in the Appenzell Alps, in the canton of St. Gallen. It reaches 2,279 metres, with a prominence of 325 metres, and rises above Lake Walenstadt. Its northern side, above the Toggenburg, carries a trail to the top.

The mountain marks the natural boundary between the Toggenburg and Walensee regions as part of the Appenzell Alps. Its limestone cliffs and steep faces have long served as important geographic reference points for mountain travelers.

The summit serves as a reference point for local mountaineers who utilize its north face trails for traditional alpine hiking expeditions.

Hikers can depart from Alt St. Johann, and the route can be shortened by using the Selamatt chairlift instead of walking the entire way. Plan for sufficient time and bring water, as the hike involves elevation gain through mountain terrain.

From the summit ridge, visitors can see the entire sequence of Churfirsten peaks stretching across the horizon, with Hinterrugg rising to the east and Frumsel to the west. This vantage point reveals how all the main peaks of the group relate to one another in the landscape.
