However, the highest peaks of the low mountain range are found on a second ridgeline, southwest of the main ridge, and which also runs from northwest to southeast. The Arber (up to 1,456 m) is linked to the Seewand to the north by a mountain ridge; to the northwest the ridgeline crosses the Schwarzeck (1,236 m) and runs up to the Kaitersberg (1,133 m); the upper valley of the White Regen, the so-called Lamer Winkel, separates this ridge from that of the Kunisch Mountains. To the southeast of the Arber, this ridge is initially interrupted by the Zwiesel Basin, in which nestles the town of Zwiesel, but continues on the far side of the basin, with the Rachel (up to 1,453 m), the Lusen (1,373 m) and the Dreisesselberg (1,333 m), the other highest mountains of the Bavarian Forest and in the whole of the Bohemian Forest too. The crest continues beyond the borders of Bavaria, along the border between the Czech Republic and Austria, crossing the mountains of the Plöckenstein (1,379 m) and Hochficht (1,338 m).
