Trojmezná hora — known on the German side as Bayerischer Plöckenstein — is a summit that offers more than just altitude. Sitting just 700 metres from the triple border point where Germany, the Czech Republic and Austria meet, this peak has a rare charm that few mountains can match.

Rising to 1362 m above sea level along a forested ridge between Dreisesselberg to the northwest and Hochficht to the southeast, the mountain straddles the boundary between the Bavarian Forest and the Bohemian Forest (Šumava). The landscape here is wild and unhurried — dense coniferous woods, granite boulders and deep forest silence. On clear days, especially during warm Foehn conditions, the views stretch all the way to the Alps, from the Totes Gebirge to the Kaisergebirge. Just below the summit lies the protected Steinernes Meer — a remarkable field of granite boulders that rivals the famous rock formations on Lusen, and whose individual blocks are actually even larger.

The long-distance European hiking trail E6 passes right over the summit, continuing from the nearby triple-border point towards the Austrian Waldviertel together with the Nordwaldkammweg.

• From the Bavarian side — starting from Pleckenstein, a district of Neureichenau (Germany) — trail through the Bayerischer Wald Nature Park, moderate difficulty
• From the Czech side — from the municipality of Nová Pec within the Šumava National Park and Biosphere Reserve

• The summit sits on the German-Czech border — accessible from both sides without special permits (Schengen area)
• The Czech side falls within Šumava National Park — stay on marked trails
• European long-distance trail E6 crosses the summit

The Steinernes Meer boulder field just below the summit is one of the most impressive granite formations in the entire Bavarian and Bohemian Forest region — a geological spectacle well worth a short detour.
