Höllkar, Mountain summit in Sankt Gilgen, Austria.

Höllkar is a 1169 m summit north of Sankt Gilgen, between the Wolfgangsee, Fuschlsee and Mondsee lakes. It rises only slightly above the small St. Gilgen valleys of the Obenau and Zeppezau near Winkl, behind the Wallhüttenkogel and Obenauerstein. The summit is partly wooded today and is reached by forest roads and marked trails into the Eibensee area.

The Höllkar appears in 19th-century alpine literature: F. G. Weidmann's 1834 guide to Ischl and Heinrich Wallmann's 1866 account of walks through the Salzburg foothills. Already in the early summer-fresh-air season the Höllkaralpe was recommended as a rewarding viewpoint. Today the summit is partly wooded.

The name pairs Höll, a dialect word for a hollow or steep gully, with Kar, a cirque. The summit rises above the small St. Gilgen valleys of Obenau and Zeppezau near Winkl, and since the early summer-resort era the Höllkaralpe was recommended as a viewpoint. The peak itself is now partly wooded.

The climb requires good fitness and sturdy footwear since the trails are steep and partly rocky. The best conditions for hiking are during the warmer months when snow and ice have cleared.

The summit is partly wooded today, so the view is not continuous. In the early summer-fresh-air era the Höllkaralpe was already recommended as a rewarding viewpoint, and the mountain is reached from the valley villages via forest roads and marked paths into the Eibensee area.
