Fronalpstock, Mountain summit in Schwyz, Switzerland

Fronalpstock is a 1,921-metre summit of the Schwyzer Alps in the canton of Schwyz, on the municipal territory of Morschach. Its western flank drops to the Urnersee arm of Lake Lucerne, where the Axenstrasse and the Arth-Goldau to Erstfeld railway run through tunnels in the rock. A chair lift reaches the summit from the car-free village of Stoos.

The mountain became a hiking destination as Swiss tourism grew in the early 20th century. Local paths were gradually developed into marked routes that connected nearby villages to the summit area.

The Fronalpstock is reached from Stoos, a car-free village above Lake Lucerne. The ridge trail from the Chlingenstock along the Fronalpstock chain ends at the summit, and an alpine route rated T4 on the SAC scale climbs from the Schwyzerhöhe area. The summit is also the site of the world's highest amateur radio relay for the 10-metre band.

The summit is reached from the car-free village of Stoos, itself accessed by funicular from Schwyz, then by chair lift to the top. A marked trail also climbs from Stoos, and the ridge route from Chlingenstock ends here; the approach from Schwyzerhöhe is an alpine route graded T4 on the SAC scale.

The Fronalpstock is the end point of the ridge trail from the Chlingenstock along the Fronalpstock chain. On the summit stands the world's highest amateur radio relay for the 10-metre band, a detail most hikers walk past without noticing.
