The Signal de Botrange is the highest point in Belgium, located in the High Fens (Hautes Fagnes in French), at . It is the top of a broad plateau, and a road crosses the summit, passing an adjacent café. In 1923, the six-metre-high Baltia tower was built on the summit to allow visitors to reach an altitude of 700 m. A stone tower built in 1934 reaches 718 m.

At the height of winter the site is used as the start of a number of cross-country skiing routes.
