The Březná rises in the Hannsdorfer Bergland in on the eastern slope of the Jeřáb ( ) in a wooded ground to the Pohořelec ( ) and the Bouda ( ) from numerous source streams. North of the source base on the pass is the chapel of St. Trinity. Not far away is the mineral-rich Rudolf Spring, which is also one of the Březná springs.
Its upper course leads through Moravský Karlov to the southwest into the Grulich furrow ( Králická brázda ). In Bílá Voda it changes its direction to the south and forms the natural border between the Eagle Mountains and the Hannsdorfer Bergland. From Moravský Karlov, the Králíky - Štíty railway follows its course. Via Mlýnice, Mlýnický Dvůr, Březenský Dvůr, Na Hutích and Březná it reaches Štíty and breaks through the Hohenstädter Uplands ( Zábřežská vrchovina ) below the town in a narrow deeply cut valley in which only the small settlement of Drozdovská is located.
Past Crhov, Jedlí , Království, Malá Stráň, Velká Stráň, Janoušov and Drozdov , the Březná joins the Moravská Sázava after 31.3 km at above the village of Hoštejn . Its catchment area is 182 km². The average water flow at the mouth is 4.21 m³ / s.
The meandering middle and lower section of the river is part of the PP Březná Nature Park. It was created in 1997 and has an area of 11,600 ha.
