Horská louka u Háje, Nature reserve near Loučná pod Klínovcem, Czech Republic

Horská louka u Háje is a 27.75-hectare nature reserve on the eastern slope of Macecha in the Ore Mountains, at 893–959 metres. Half of it is mat-grass turf, a third wetland, and the rest mountain peat spruce forest in the south. A stream, Černá voda, flows through it.

The area became a protected reserve on May 16, 1994, designated by the Chomutov district office to safeguard one of the last mountain meadows remaining in the Ore Mountains. This protection came as a response to the widespread loss of such grasslands across the region.

The meadow's northern edge held the hamlet of Königsmühle, a poor pasture settlement that vanished in the second half of the 20th century. Its ruins, an overgrown millrace and a sunken cart track more than two metres deep in places remain, and the path from Háj is marked with an arrow for Königsmühle.

You can access the reserve by field path from the village of Háj or via a forest trail from the Selský les crossroads. The best time to visit is from May through September, when the meadows are fully open and the paths are easier to walk.

The meadow also catches drinking water for the surrounding villages, and a small tributary of the Černá voda was straightened and deepened in the 1970s and 1980s, drying the site until the stream was dammed after 1994. Plantings of blue spruce and dwarf pine from the same period failed and are now cleared.
