From the Tonnerhütte parling lot, follow the slightly ascending forest road to the 1st hairpin bend. Immediately from the bend, the footparth branches off the right and turns towards the right edge of the ski slope. Follow the course pf the slope to the Hohe Hald. Out of the increasingly sparse tree line, the path now leads us slightly uphill over treeless terrain in the direction of the Zirbitzkogel, before turing east (half-right) and heading towards the Murtalblick at the Lavantsee, 2.250m. There you have a wonderful view into the Murtal and to the Lavantesee.
Follow the ridgt to the N (left), the mark 312 to the summit of the Zirbitzkogel. Not far form the summit is the Zirbitzkogel-Schutzhaus, which invites you to stop for a break. From the Zirbitzkogel shelter, follow the trail 320 to the east.
Follow the mark 45 to the SE over steep terrain to the Lavantsee lake. Continuing to follow maker 45, the descent leads over steep, treeless terrain to the Köhler Hütte. After a short stretch downhill in the SE direction, you reach the very young Lavant. Through oark-like stone pine forest, The Judenburger-Wallfahrerway now winds its way in a S direction.
Past a wooden cross and a spring, you reach the 1st turnoff to Wildsee. Slightly ascending trrough a small high valley, trail 312 leads to Wildsee, 1.981m. Pass the south side of the Wildsee to the W across the open plateau, climbing moderately to the ridge running from the Zirbitzkogel to the south. Follow the course of the ridge to the N on the Fuchskogel, 2.114m. The summit cross of the Fuchskogel is slightly offset to the NE away ftom the marked path. Take trail 321 on the slightly ascending ridge to the N until you reach the fork at the top of the Lavantesee. Turn left (W) and follow the trail, which is always slightly descending, past the hiker's watering hole, 2.073m to the Hohe Hald. Via the gently descending, marked Zitbitzkogelway you reach the ski slope to the bend of the forest road and further to the starting point, the Tonnerhütte.
