The Zwercheck (Czech: Svaroh) is a 1,333-meter-high mountain in the Bohemian Forest (Künische Gebirge), a mountain ridge between Bavaria and Bohemia. The border between Bavaria in Germany and Bohemia in the Czech Republic runs along the ridge. On the broad, open, rounded summit are a meadow and a small rocky outcrop with a summit cross and good views across to the Großer Arber and the Kaitersberg, and down into the Lamer Winkel valley.

The border trail is very rocky and every step has to be well placed. Although the terrain is flat, the trail is still strenuous.
