From the Dreisesselberg, a ridge, the Hochkamm, leads across to the Bavarian Plöckenstein (1,365 m) and via the tripoint between Germany, Austria and the Czech Republic (1,321 m) to the Austro-Czech border on the main summit of the Plöckenstein (1378.3 m). It runs along the German-Czech border and then on the Austria-Czech border. Just below them is on the Czech territory Plöckensteinersee, the southernmost glacial lake of the Bohemian Forest.
