Pferdskopf, Mountain summit in Rhön Mountains, Germany

Pferdskopf is an 874.9 m high southwestern spur of the Wasserkuppe in the Rhön, near Poppenhausen in Hesse. Its summit exposes a trachyte dome with platy jointing overlying dark basalt; the colour change from light grey trachyte to dark basalt is visible in the rock. The bare summit area offers views to the west and northeast toward the Wasserkuppe.

The summit exposes the eroded base of a volcanic ruin: a light-grey trachyte dome with platy jointing overlying dark alkali basalt, partly as basaltic tuff. The colour change between the two rocks is visible in the field. Because of these structures the summit area was designated a protected geotope, and a geological trail runs from the Pferdskopf to the neighbouring Wasserkuppe.

The 863-metre Karfreitagsstein, a basalt outcrop northeast of the summit, takes its name from a legend: on Good Friday, when church bells ring up to it, the rock is said to turn three times on its own axis. A geological trail runs from the Pferdskopf to the neighbouring Wasserkuppe, explaining the local rocks.

The summit is reached on foot; the Hochrhönring runs past the mountain to the southwest, and a geological trail connects the Pferdskopf with the neighbouring Wasserkuppe to the northeast. The bare summit area opens a wide view to the west, while the Karfreitagsstein basalt outcrop lies just northeast of the top.

Northeast of the summit lies the Karfreitagsstein, an 863-metre basalt outcrop also called Lerchenküppel or Steinküppel. Legend says the rock formation turns three times on its own axis when church bells ring up to it on Good Friday.
