Hoher Kasten is a mountain in the Appenzell area, with panoramic views of Eastern Switzerland and lots of hiking options. This hike starts at the top of the Brülisau-Hoher Kasten cable car, descends ~400m over ~5.5km to the Ruhesitz guest house, where you can rent a trotti scooter to ride the rest of the way down on a paved road. In the middle of the trail, there is a nice detour to a pretty pond in the forest, an extra 3km loop but well worth it.
The views are spectacular and the hike varied: rocky steps, forests, fields, gravel paths, cow pastures, paved roads, muddy bogs, etc. The hike is not particularly difficult since it is mostly downhill, but it is long and could be challenging for very small children. Instead of hiking, you can simply enjoy the view from the complex atop Hoher Kasten, with a rotating panorama restaurant, open year round. We really liked this area and plan to go back and tackle some of the more challenging hikes along the mountain ridges to some alpine lakes and mountain huts.
