Pramenáč, Mountain summit in Košťany, Czech Republic

Bornhauberg, called Pramenáč in Czech, is the highest point of the Cínovec Highlands at 910 metres. Its broad, flat summit ridge holds remnants of a levelled surface with peat bogs, while the steeper southeast slope carries scattered scree and scree flows. Spruce forest covers the mountain, mixed with a little birch and pine.

Pramenáč lies in the Cínovec Highlands, the highest point of that range at 910 m. Its summit area keeps remnants of a levelled surface with peat bogs, while the steeper southeastern slope carries scattered scree and scree flows. The mountain is forested with spruce, with a little birch and pine.

The Czech name Pramenáč and the German Bornhauberg both appear on maps and in records, a pairing typical of the Krušné hory borderland. The summit lies in the cadastre of Košťany, though the village of Mikulov v Krušných horách sits 2 km to the southwest. The moorland on the northeast shoulder is marked on older maps as "Die See".

No marked trail leads to the summit; from the European long-distance path E3 at the Vitiška lodge, a forest road reaches the top in about 20 minutes. In winter a cross-country ski trail network runs over the forest roads and across the summit itself.

On the northeastern shoulder of Bornhauberg lies a high moor complex, marked on older maps as "Die See", which reaches as far as the Georgenfelder Hochmoor on German territory. In winter a cross-country ski trail network runs over the forest paths and across the summit itself.
