Pecopala, Mountain summit in Doksy, Czech Republic

Großer Petzberg (Pecopala) is a neovolcanic summit at 453 m in the Česká Lípa district, rising from the sandstone plateau of the Hradčanská pahorkatina, of which it is the second-highest point. It lies about 4.5 km northeast of Doksy within the Břehyně-Pecopala National Nature Reserve. A slowly overgrowing viewpoint on the northern slope looks toward the Hradčanské bučiny beech woods, Dub hill, part of the Ralská pahorkatina and the Lužické hory.

The summit area was part of the former Ralsko military territory, which restricted access and shaped regional development for decades. After this restricted zone closed, the area gradually opened to the public for recreation.

The name Pecopala, also shortened to Pec, is used for the hill and its cadastral area, and the surrounding forest is part of the Břehyně–Pecopala national nature reserve. The northern slope has a slowly overgrowing viewpoint toward the Hradčanské bučiny beech woods, the Dub hill, part of the Ralská pahorkatina and the Lužické hory.

No path leads to the summit; the nearest walking and cycling route is the Dělová cesta, which starts at the Trojzubec forester's lodge on road II/270 between Doksy and Mimoň. A car can be left there. A slowly overgrowing viewpoint on the northern slope looks toward the Hradčanské bučiny beech woods, Dub hill, part of the Ralská pahorkatina and the Lužické hory.

The summit offers views down to Břehyňský Pond, where a historic building on the dam once functioned as the Zum Taichrose inn. Today it houses apartments but remains a noteworthy landmark in the landscape.
