Drachenfels, Mountain summit in the Palatinate Forest, Germany.

Drachenfels is a 570.8-metre hill of Bunter sandstone in the central Palatine Forest, on the forest estate of Bad Dürkheim. Its roughly 13-hectare summit plateau, highest in the northeast, rises above the surrounding hills and drops to about 540 metres at the edges. Below the rock jutting out to the southeast lie two hollows, the Drachenkammer and the larger Drachenhöhle.

The summit plateau holds the remains of a late Roman fortification from the 3rd century, laid out as a double rampart and now barely visible under vegetation. A further, presumably older rampart also survives. In 1873 the Drachenfels Club, founded that year to care for heritage sites around Bad Dürkheim, began opening the hill to visitors.

The hill's name, like that of the Siegfriedsbrunnen spring at its southern foot, is linked to the dragon of the Nibelung legend. Below the rock jutting out to the southeast lie two hollows, called the Drachenkammer and the larger Drachenhöhle. The spring was renamed by the Drachenfels-Club after the hero Siegfried.

The summit is reached only on foot, over steep woodland tracks and paths that are unsurfaced in places; riding and mountain bikes are not allowed in the nature reserve. The nearest hiker's car park is at Forsthaus Saupferch, about 2 km from the B 37 on a metalled road, with a trail map of the Palatine Forest Club. Long-distance trails, including the Staudernheim–Soultz-sous-Forêts route and a yellow-barred path from Glanbrücken to Wachenheim, cross the hill.

The Drachenfels Club, founded in 1873, opened the summit to walkers in its first year and still maintains the paths and rock area. Its members also renamed the Friedrichsbrunnen spring at the southern foot after Siegfried, tying the site to the Nibelung legend.
