Kraina Rudaw, Geomorphological subprovince in northern Czechia.

The Erzgebirgs-Subprovince spans mountainous terrain with metamorphic rock formations and numerous valleys situated between the Czech Republic and Germany. The landscape shows a complex geological structure with varied mineral deposits appearing at different elevations throughout the region.

Medieval miners extracted large quantities of silver, tin, iron, and copper from the mountains, which led to the establishment of numerous settlements throughout the area. This mining activity shaped settlement patterns and regional development for centuries afterward.

The name Erzgebirge means "ore mountains", and the Czech name Krušné hory carries the same meaning. The range is divided into the Klínovecká hornatina and Loučenská hornatina, and the German side forms part of the Östliche Mittelgebirge natural region. The subprovince also takes in the sandstone walls of the Děčínská vrchovina and the volcanic hills of the České středohoří.

Hiking trails wind through the area connecting mineral sites, with informational geological panels positioned along the routes to explain the formations. Visitors should wear weather-resistant clothing since the mountainous location can experience sudden weather changes.

The area comprises two distinct mountain divisions called Klínovecká hornatina and Loučenská hornatina, each with its own rock formations and mineral compositions. This geological split creates a varied landscape with different mineral deposits found across relatively short distances.
