The Lomná (German Lomna ) is a left tributary of the Olsa in the Czech Republic .

course

The Lomná rises southwest of Hruška near the Slovakian border in the Jablunkauer Bergland . Its source is located at the northern foot of the Čubaňov saddle (1101 m) between Burkov vrch (1031 m) and Malý Polom (1060 m). It flows through a deep, forested valley in which the villages of Hruška, Kyčmol, Horní Lomná , Stoligy and Tatínky are located, initially to the northeast. Below Tatínky the Lomná turns to the east and flows through Radošonka and Dolní Lomná . The river then takes a north-easterly direction and is bridged by the Žilina – Bohumín railway line, which then follows the Lomná to Jablunkov. East of Novina, the Lomná flows after 13 kilometers out of its wooded mountain valley into the Jablunkau furrow ( Jablunkovská brázda ). Along its lower reaches are the places Pod Břehy, Městská Lomná, Bocanovice , Ošetnice, Červená and Jablunkov . On the northern outskirts of Jablunkov, the Lomná finally flows into the Olsa after 17.5 kilometers .

North-east of Horní Lomná, the Mionší National Nature Reserve extends along the Velká Polana (893 m) with its primeval forest of fir and beech trees.
