Sonntagshorn is the highest peak of Chiemgauer Alpen area. As the whole area consist of mountains with low to moderate heights, Sonntagshorn does not even reach 2000 m. Nevertheless the northern aspect of Sonntagshorn is a rather wild and rugged one and the altitude difference from valley to top is nearly 1300 m.
Sonntagshorn is the culmination point of an east – west running ridge between Unken and the Saalach valley to the south and the Schwarzachen valley to the north.
The nearly equally high Reifelberg, Vorderlahnerkopf and Hirscheck are standing to the west, the secondary summits of Aibleck and Hochgern are located to the east of that ridge. A sidekick on the south ridge of Sonntagshorn is Peitingköpfl, a nice meadow summit above the village of Unken.
The Sonntagshorn main ridge markes the border between Germany and Austria, too, The gentle south side of the mountain belongs to Austria, this side hosts the two south routes which are frequented, not to say crowded, on sunny days. The northern German side, however, is a wild landscape with the three, south – north orientated Kraxenbachtäler (valleys). Kraxenbach valleys are my preferred route for summiting Sonntagshorn. As the north route is rather long and includes some rock scrambling you will not meet many co-hikers.

Sonntagshorn Routes Overview
The north route uses the Schwarzachen valley up to Schwarzachen Alm and enters the Kraxenbach valley system.
There are two routes to the summit which can be combined to a nice traverse:
South route from Heutal:
Follow the road into Lahnersbach valley and ascend on a trail to Trostberger Hütte. Follow the forest road up through the Alm hut village and go straight on on a trail where the road bends to the right. Climb Perchthöhe, the col between Peitingköpfl and Sonntagshorn on that trail. Turn left and zigzag up the south slopes to the uppermost west ridge of Sonntagshorn. Turn right and climb the summit.
The Heutal route is the ski route, too.
South Route from Unken:
From the parking area at Unkener Landstraße follow a trail up to Peitingköpfl. The trail crosses a forest road several times. Descend shortly to Perchthöhe and ascend first the south slopes and then the uppermost west ridge to the summit.
A long route goes up from Unken / Melleck or from Weißbach to the ruined Unzentaler Alm and to Aibleck, From there you can summit Sonntagshorn via its east ridge. Long an unusual ascent.
The whole German part of Sonntagshorn is a Nature Protection Area. There is no entrance fee but several restrictions like:
Accommodation of all kind can be found at:

You can summit Sonntagshorn the whole year.
The north route is only possible in summer through autumn until the first snow falls. The route requires rock scramble and short climbs up to grade II.
The south routes are easy hikes in late spring through autumn. The ski tour route from Heutal is an easy one for beginners.
In summer you need hiking gear and good shoes.
