South of Partenkirchen is the Partnach Gorge, where the Partnach river surges spectacularly through a narrow, gap between high limestone cliffs. The Zugspitze (local name Zugspitz) is south of Garmisch near the village of Grainau. The highest mountain in Germany, it actually straddles the border with Austria. Also overlooking Garmisch-Partenkirchen is Germany's fourth-highest mountain, the Leutasch Dreitorspitze (Three-Gate Peak, a name derived from its triple summit).
