Jański Wierch, Mountain summit in Krkonošsko-jesenická range, Czech Republic

Jański Wierch (Janský vrch, 697 m) is the highest Polish summit of the Jastrzębie Mountains, about 2.5 km southwest of Okrzeszyn. The Polish-Czech border runs over the top and turns northwest there. The massif is built of Upper Carboniferous sandstones and conglomerates of the Intra-Sudetic Basin, with numerous rock outcrops of conglomerate and sandstone on the summit, ridge and slopes.

The summit lies on the Polish-Czech border, which turns northwest at the top; the state boundary has followed this line across the ridge. The massif is built of Upper Carboniferous sandstones and conglomerates of the western wing of the Intra-Sudetic Basin, and the summit, ridge and slopes carry numerous rock outcrops of conglomerate and sandstone.

The state border runs across the summit and turns northwest there, so hikers can stand on the Polish-Czech line. A green section of the Border Trail (Szlak Graniczny) links the Mieroszowskie Ściany with the Okraj pass, while on the Czech side a yellow trail runs from Bernartice to Petřikovice.

A green trail along the Polish-Czech border crosses the summit, part of the Border Trail from Mieroszowskie Ściany to the Okraj pass. On the Czech side a yellow trail runs from Bernartice to Petříkovice. The former Okrzeszyn–Petříkovice border crossing lay southeast of the massif.

The summit lies exactly on the Polish-Czech border, which turns northwest at the top. The massif is built of Upper Carboniferous sandstones and conglomerates of the Intra-Sudetic Basin's western wing, with rock outcrops on the peak, ridge and slopes.
