Šeřín (1,035 m a.s.l.) is a rewarding summit in the Krkonoše (Giant Mountains) of the Czech Republic, crowned by an impressive phyllite rock formation with a viewing platform and stone steps carved into the hillside over a century ago. Sitting about 4.5 km south-west of Špindlerův Mlýn, it offers a quieter alternative to the busier trails of the national park.

The peak is the third along the north–south Žalský Ridge, which forms the watershed between the Elbe and Jizera river basins — streams on the eastern slopes feed directly into the Elbe, while those on the west drain into the Jizerka. The hillsides are mostly forested, opening up into meadow clearings around small mountain hamlets: Janova Hora, Zákoutí, Čistá Voda and Třídomí. In winter, the area comes alive with a handful of small ski tows.

• From Jilemnice or Špindlerův Mlýn — follow the red-marked 'Bucharova cesta' trail, which runs north–south through the summit; this path is suitable for hikers only, not cyclists or vehicles.
• The flanks of the mountain are accessible via forest roads of varying quality.

• The summit lies within Krkonoše National Park (KRNAP) — park regulations apply throughout.
• A short freight cable car on the eastern slope supplies the Bumbálka mountain hut — it is not open to passengers.
• Just before the summit, in the last bend on the trail from Rovinka, is a spot called 'Bergrovo zátiší', named after a forestry official who was killed here by an avalanche on what was then an open, treeless slope.
• A plaque dated 1875 on the summit rock commemorates the surveying of the Harrach estate.

The stone staircase leading up to the summit viewpoint was built in July 1893 — for over 130 years it has been welcoming hikers to one of the finest vantage points along the Žalský Ridge.
