Kaňon Blanice, Nature reserve in Volary and Záblatí, Czech Republic.

Kaňon Blanice is a nature reserve of 130.98 hectares along the Blanice River between Hus Castle and Řepešínský Mill, at elevations of 608–780 metres. Its steep valley slopes carry mostly coniferous forest, with spruce and pine making up 90 percent of the trees, and short side valleys cut by Milešický and Křemenný streams.

The area belonged to the Hus Castle estate from the first half of the 14th century. King John of Luxembourg authorized brothers Jenšík, Vavřinec, Herbort and Pešek of Janovice to build the castle in 1341. A century later, the robber knight Habart Lopata of Hrádek seized and demolished it.

The reserve draws hikers seeking to explore its forested valleys and river landscapes on foot. The marked paths connect the surrounding communities and offer ways to experience the woodland environment directly.

The area is served by a network of marked hiking routes that guide visitors through the terrain. The main blue-marked path offers straightforward navigation for those exploring the reserve.

The reserve protects the freshwater pearl mussel (perlorodka říční), along with the brook lamprey, the common minnow and the greater mouse-eared bat. The northern part absorbed the former Na soutoku reserve, and the whole area has belonged to the Šumava protected landscape since 1963 and to the Šumava European site since 2004.
