The Hackenköpfe are a row of peaks in the western Kaisergebirge range in Austria. Their maximum height is 2,126 metres (6,975 ft). They are located in the ridge running west from the Sonneck between the Treffauer and Scheffauer. To the north their rock faces, up to 800 metres high, drop into the Kaisertal valley; to the south they present steep, craggy rock flanks. They are most usually scaled either from Sonneck or from the other side from the Scheffauer. Both normal routes include sections of UIAA grade II climbs and are not signed or secured. The popular, but challenging crossing of the crest running from the Scheffauer to the Sonneck from the base at Scheffau am Wilden Kaiser also involves the Hackenköpfe.

For completing this tour, good fitness and sufficient water and food are necessary! The crossing of the Hackenköpfe is often pathless or just a trail. Orientation and sure-footedness are mandatory! 

Pay attention to isolated little cairns, very few markings or poles. Mostly Difficulty II (UIAA) and depending on the way to the III. No ropes!

The ascent to the Treffauer and the following descent over the Tuxeck should not be underestimated after this tour. At the junction of Sonnenstein, you have about half of the tour behind. At this point, you can optionally shorten the tour and go directly to Kaiseralm.
