The high moor plateau on the summit is a protected habitat for rare, specialized plants including sundew and cotton grass.
The name 'Hornisgrinde' likely derives from 'Horne' (peak) and 'Grinde' (an Alemannic term for a treeless, mossy mountain summit).
The summit plateau remains largely treeless due to the harsh wind conditions and the unique bog-like soil composition.
A portion of the mountain formerly housed a restricted NATO military installation, which is now largely decommissioned.
The mountain marks the boundary between the German states of Baden-Württemberg and the historical regions of the Black Forest.
At 1,164 meters, Hornisgrinde is the highest mountain in the Northern Black Forest, characterized by a large high moor plateau that separates the Rhine Valley from the Murg Valley. The summit area features a distinctive landscape of wind-swept moorland and an observation tower that provides 360-degree panoramic views of the Vosges mountains and the Black Forest range. A military radio tower remains a prominent landmark on the plateau, marking the summit's history. The terrain supports a mix of alpine meadows and coniferous forests, accessible via extensive hiking networks. In winter, the area serves as a local hub for cross-country skiing and winter sports enthusiasts. The geological foundation consists of Bunter sandstone, which influences the acidic soil composition of the moorland.

Bring wind-resistant layers even in summer, as the plateau is highly exposed to strong mountain breezes.
Stick strictly to the marked wooden boardwalks when crossing the moor to protect the fragile ecosystem and avoid sinking in boggy terrain.
Carry binoculars to identify the peaks of the Vosges across the Rhine Valley.
Attempting to hike off-boardwalk paths which can be dangerous and damaging to the environment.
Stay on marked paths to protect the sensitive high-moor vegetation; no off-trail hiking.
