Groot Summit Marker

Groot - Highest Point in the Canton of Thurgau
With the Groot (991.1 m), we head to the highest elevation in the Canton of Thurgau: literally "the Top of Mostindien." Interestingly, about 10 m further on lies the so-called ridge, which is also the highest point of the elevation. It rises 5 m higher than the Groot and is located entirely in Mosnang, or rather, in the Canton of St. Gallen. On this tour, we explore the idyllic Tössberg region.

A nice place with a wonderful view

According to the board 991.1 m high (at the TG/SG boundary stone), but not definitely the highest point in the canton of TG (there the information differs...could also be at the Hörnli).
The highest point there (slightly next to the border stone) is 996 m, but this is already in the canton of St. Gallen.
