Geigerskopf, Mountain summit in Northern Black Forest, Germany

Geigerskopf is a 436.2 m high mountain in the Northern Black Forest, on the territory of Bottenau in the Ortenaukreis. Its ridge separates the Hesselbach valley from the foothills of the Rhine valley. On the summit stands the 20 m high Geigerskopfturm, a metal observation tower painted in rainbow colours.

The mountain first gained a viewing platform in 1884, marking its emergence as a destination for visitors in the region. A steel observation tower was constructed in 1909, replacing earlier wooden structures and becoming a defining landmark of the site.

The 20-metre tower on the summit was built by the Oberkirch branch of the Schwarzwaldverein, the Black Forest hiking association, and inaugurated on 18 July 2000. Its rainbow paint makes it a local landmark, and the club maintains it as a free viewpoint over the Rhine Valley.

The mountain can be reached from Oberkirch via marked hiking trails, with parking facilities near the starting points. The paths are generally well-maintained and accessible to hikers of varying experience, so comfortable hiking boots and basic supplies are useful to bring along.

The steel observation tower at the summit is painted in rainbow colors and offers views reaching to the Vosges Mountains across the Rhine Valley on clear days. This colorful feature makes the structure visible from great distances and gives the site a memorable quality that sets it apart from comparable installations in the region.
