Sedlo, Mountain summit in Šumava National Park, Czech Republic.

Sedlo is a broad, wooded summit of 905 m in the Šumava foothills, in the cadastre of Albrechtice, Klatovy District. Its ridge runs northwest to southeast, with gentle slopes on some sides and steep, stony ones, especially to the south. Rock formations lie near the top, where a rock viewpoint drops away in a steep cliff several tens of metres high.

Sedlo is topped by the remains of an early Celtic hillfort (hradiště), whose ramparts follow the elongated northwest–southeast ridge. A military observation tower later stood on the summit; it decayed, and a wooden lookout was built in its place, opened on 13 December 2009.

A New Year's Eve ascent from Albrechtice to the summit is a local tradition. The wooden lookout tower opened on 13 December 2009; its construction was funded partly by a public collection in which donors could buy individual steps and are named on them as a reward.

The summit is reachable via marked hiking trails from Albrechtice, with the climb taking around three hours through varying terrain depending on fitness level. Good hiking boots and weatherproof clothing are important since conditions at elevation can change quickly.

The summit holds the remains of a Celtic hillfort whose ramparts follow the elongated ridge from northwest to southeast. A wooden lookout tower opened here on 13 December 2009, and its 23.75 m viewing platform stands on a heptagonal plan.
