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.

From the Osserwiese there are good views of the small Osser and the Lamar Winkel. It also serves as a launch site for paragliders.

Reviewers often praise the challenging nature of the routes, the expansive views of the Bohemian Forest landscape, and the opportunity to summit prominent peaks like the Great Osser and Kleiner Osser.
While many trails in the Bohemian Forest are dog-friendly, the challenging nature of the mountaineering routes around Dam Nýrsko means they are best suited for fit, experienced dogs accustomed to rugged mountain terrain. Always ensure your dog is on a leash and that you carry enough water for both of you. Check local regulations for specific areas.
The best time for mountaineering around Dam Nýrsko is typically from late spring to early autumn (May to October), when the weather is more stable and trails are clear of snow. During these months, you'll experience pleasant temperatures and the full beauty of the alpine meadows and forests. Winter mountaineering is possible but requires specialized equipment and experience due to snow and ice conditions.
While the routes themselves traverse rugged mountain terrain, you may find refreshment opportunities in nearby villages or at mountain huts, particularly around popular starting points like Sattel or Sommerau. It's always advisable to carry sufficient water and snacks, as facilities directly on the trails can be limited.
The Bohemian Forest, including the area around Dam Nýrsko, is rich in wildlife. Keep an eye out for red deer, wild boar, and various bird species. If you're very lucky and quiet, you might even spot elusive animals like lynx or capercaillie, though these are rare sightings. Respect their habitat by staying on marked trails and keeping noise to a minimum.
Generally, you do not need a specific permit for mountaineering on established trails around Dam Nýrsko. However, as parts of the region fall within protected landscape areas or national parks (such as the Šumava National Park on the Czech side), it's crucial to respect all local regulations, stay on marked paths, and avoid disturbing wildlife or nature. Always check for any specific restrictions before your trip.
