Sedielko, Mountain pass in High Tatras, Slovakia.

Sedielko is a saddle at 2376 m in the main ridge of the High Tatras, between Široká veža (2461 m) and Malý Ľadový štít (2602 m). Its western slopes drop into Zadná Javorová dolina, its eastern slopes into Dolinka Lodová, a branch of Malá Studená dolina. The ridge descending from Široká veža to the saddle carries several small rock formations, from Harnaski Karbik down to Harnaskie Czuby.

The first recorded crossing was made on 13 August 1854 by Feliks Berdau, Wojciech Grzegorzek and Józef Stolarczyk with their guides. In winter, Károly Jordán crossed on 5 January 1902 with guides Johann Franz senior and Johann Hunsdorfer junior. In the 19th century large firn fields lay on both sides of the pass, making the crossing much harder, yet in 1891 an infantry battalion passed through.

The pass links two valleys, not three: the Malá Studená dolina on the Slovak side and the Zadná Javorová dolina on the Polish side. Its Slovak name Sedielko means "little saddle"; Polish hikers call it Lodowa Przełęcz, and German maps mark it as Kleiner Sattelpass. The green-marked trail from Téryho chata reaches it past Modré pleso.

The hiking trail closes during winter months due to snow conditions and requires good physical fitness because of steep approaches. Visitors should bring appropriate mountain gear and have experience with high-altitude hiking.

In 1891, before the snowfields shrank, an infantry battalion crossed this 2,372 m saddle. The ridge above it, descending from Široká veža, carries a run of small named rock steps, from Harnaski Karbik down to Harnaskie Czuby, which most walkers pass without noticing.
