Plattenhausenriegel, Mountain summit in Bavarian Forest, Germany

Plattenhausenriegel is a long ridge running across the German-Czech border between the Großer Rachel and the Lusen, with a higher southern summit at 1,376 m in Bavaria and a lower northern summit at 1,368 m in the Czech Republic. Its inconspicuous top is a rock formation about 5 m high, and the mountain lies in the core zone of the Bavarian Forest National Park.

The summit lies in the core zone of the Bavarian Forest National Park, Germany's first national park, established in 1970. On 20 June 1963, two Czechoslovak MiG-15 jets crashed west of the Plattenhausenriegel on German territory, killing both pilots.

The summit sits on the border between Germany and the Czech Republic, and old boundary stones marked with the blue-and-white Bavarian diamond pattern run along the ridge. These stones have stood in the landscape for generations and give the path its distinct character.

The hike starts from the Fredenbrücke parking area in Neuschönau and is a long, demanding route that requires sturdy footwear and good physical condition. The trail passes through the national park, where some sections may be subject to seasonal closures.

The summit is reachable only via the unmarked border path, open from 15 July to 15 November each year under the national park ordinance. The rest of the year it is closed, so the access season runs mid-July to mid-November, not the reverse.
