Celtic hillfort and ruined inner ring wall on Heiligenberg offering textured stone ruins, forested slopes and broad panoramas over Heidelberg, the Neckar valley and Schloss Heidelberg. Accessible by marked hikes from parking at the base (no entry fee). Best at sunrise or golden hour for warm light and long shadows; autumn and misty mornings add mood. Trails are uneven—sturdy shoes advised. Weekdays are quieter; limited parking near trailheads.
