The North Ridge that leads to the Augstenberg is approached from the town of Malbun. There are two options here. Either hike up to the ridge along the road that switchbacks up, or take the ski lift (the only one on the east side of town) for about 10 Euros. Either way will get you to the ridge.
Once on the ridge, head south on the small trail. The ridge soon becomes quite narrow, with 1,000 foot drops on either side. You're pretty close to the Austrian border here, which is in the valley to the east. Soon the trail will start to climb a little, and the ridge that you're on will turn to the west, towards the summit. Views are spectacular, and stretch from Germany to the north, Austria to the east, and the rest of the Alps to the south. The trail travels along the tops of cliffs that fall back down to Malbun. The trail steepens on the final stretch to the summit. The whole country of Liechtenstein is visible from the summit. Re-trace your steps back to Malbun, or continue south to the Naafkopf and beyond.
Water, good shoes. In winter, snowshoes, crampons and ice axes will be needed.
