Altkönig

Altkönig, one of the highest peaks in the Taunus near Kronberg, offers a rewarding mix of nature, history, and wide views over the Rhine-Main region. Popular with hikers and cyclists, the wooded mountain is known for its peaceful trails and the remains of a Celtic ring wall near the summit, hinting at the area’s ancient past. It makes a worthwhile excursion for visitors seeking outdoor activity close to Frankfurt, with a setting that feels distinctly removed from the city.
