<approach>From the Bergrestaurant, take path 201, ignoring the left turn to the plateau at Egglgrube. Pass the junction path left to Kratzer and continue until a red upper-case Omega is seen in the middle of the path, marking Kat. 28 (we think). There is a well-marked (cairns and red paint spots/arrows) branch path here. Follow this for about half an hour to the back of the limestone knoll known as "The Nipple" (and Weisse Warz and bunter's bulge). Things to note: first there is a wire traverse then you pass the lightninged tree in a sizeable valley. (Opposite this tree is the point you would turn left for Schwabenscacht). Shortly after that a pair of red arrows point in opposite directions. Go steeply uphill here doubling back slightly, rather than the more obvious straight on. Turn right about 40m beyond the nipple and head across the limestone for a narrow gully. After a hundred metres or so new red paint marks appear and take you to 40a. A very large cave entrance, 20 minutes further on, was the German's (Munich) bivouac, and a few minutes later, a strongly draughting (out in summer) tube about 5m in diameter is the main entrance ("Hauptportal" - 40a).</approach>
