In the footsteps of the ancient rock paintings of the Waaler. We start at the IceForum in Laces and follow trail no. 5 to the Margrinböden picnic area. There we enjoy the view over the castle ruins of Ober- & Untermontani. We then continue to the fork in the path where we follow path number 5a downhill to the Bierkeller. From there, the route leads through the orchards along the tarmac road back to the starting point. Variation: if you prefer a longer walk, you can descend from the Marginböden via the ruins of Ober- & Untermontani Castle and walk back along the irrigation channel path Mareinwaal via the Bierkeller.
