Hohe Flum, Mountain summit in Baden-Württemberg, Germany.

Hohe Flum is a mountain summit in Baden-Württemberg reaching 536 meters in elevation and forming part of the Dinkelberg range. An observation tower sits atop the peak, and multiple hiking trails of varying difficulty provide access to the summit area.

The observation tower was built in 1874 through community fundraising and served as a military lookout post during both World Wars. Over time the mountain became a popular hiking destination attracting visitors from the surrounding region.

Since 1993 the Wiesental riding club has held a star ride to the Hohe Flum each All Saints' Day; in 2017 more than 200 riders from Germany and Switzerland took part. The tower was handed to the community of Wiechs during the Schopfheim district singers' festival on 8 August 1874 and inaugurated the next day.

A paved side road branches off the K 6336 near Wiechs and leads up to the summit area; the Rheinfelder Weg runs along the western flank. The Hohe Flum is a stop on variant B of the twelfth stage of the Schwarzwald-Westweg from Pforzheim to Basel. The stone tower is a listed building; 62 steps lead to the viewing platform.

From the observation point visitors can see three countries on clear days: Germany's Black Forest, France's Vosges Mountains, and Switzerland's Jura range. This wide view from the summit explains why the site held military importance in the past.
