The Hornisgrinde is the highest point of the Northern Black Forest at 1163 metres. The summit plateau is unexpectedly flat and treeless, covered in raised peat moor — one of the few high moors in central Europe — and crossed by boardwalk paths to protect the bog. Two stone towers crown it: a 19th-century lookout in the south and a former French military radar mast in the north.
A car park beside the Mummelsee gives access; the walk up takes about 45 minutes through spruce and heather. On a clear day the view runs west to the Vosges and south to the Swiss Alps. The plateau weather is volatile — bring layers — and the boardwalk can be slippery in rain. From Freudenstadt the drive is about an hour up the Schwarzwald Hochstrasse.
