Popular hike in the Upper Bavarian Forest Nature Park, Bavaria.
The starting point is the car park in Lambach at the fairytale and ghost castle. From there you hike to the right past the fairytale and ghost castle on a paved path to the cast-iron Madonna (on the way you pass a few stations on the wooden path, a natural history educational trail). When you reach the statue of Mary, turn right and follow the signs to La3. In addition to the telephone line carried by wooden poles, the stony hiking trail runs steadily uphill until you meet the La1 hiking trail at a crossroads. Both hiking trails now run together for a while, past the Teufelstritt (rock with a carved sign) to a wood storage area. The La3 marking leads to the right in the direction of Osserwiese. There you have a panoramic view of the Bavarian Forest mountains - from the Kleiner Osser over the eight thousand from the Großer Arber to the Eck, Riedlstein and Kaitersberg to the Hohenbogen. At the end of the Osserwiese you can choose the narrow, uphill path over the Kleiner Osser or the shorter and easier path past the Künische chapel, where the different paths meet again. The Großer Osser is in sight at the signpost tree with the signposts. Passing the hut of the Lam mountain rescue service, the ascent begins over the rocky summit ridge to the Großer Osser (1293m). After some refreshments at the Osserschutzhaus, it's the same way back to Lambach.
