At 80 km is a roundabout; go three-quarters of the way around and follow signs to Bernau. Using your map and road signs, continue on #305 under the Autobahn to Prien. At 94 km you will drive under some railroad tracks and enter Prien, there will be a large McDonalds on the left. At 95.7 km turn right and follow signs to Chiemsee.
Near the Prien/Stock Hafen (harbor) are several parking lots charging about $2.50 to park the car while you take a boat to Herrenchiemsee Castle. Allow at least 90 minutes for the roundtrip: 15 minutes on boat to the Herreninsel, a 20-minute walk to the castle, a 35-minute castle tour, 20 minutes more back to the boat, and then the 15-minute return by boat to the parking lot. You may want to add lunch and a visit to the museum (included in the approximately $7 castle tour ticket) to that schedule. The roundtrip boat ride costs about $6.50.
Herrenchiemsee, undertaken by Ludwig II after the more famous Neuschwantstein and Linderhof, was his final fling at fantasy castles. Modeled after Versailles, it was never finished and the young king spent only a week there. His building spree had emptied the Bavarian treasury and he drowned under mysterious circumstances in Lake Starnberg, south of Munich.
Back in the car, retrace your steps until you see signs to Wasserburg and Rimsting. If you've followed our route exactly, at 102.7 km you will turn right to Seebruck. On maps this is a yellow road edged in green (scenic) and runs along the lake. At 108.7 km make another right turn toward Seebruck and at 110 km, at the crest of the hill, is a fine view of the lake. Continue on, following the Traunstein and Seebruck signs. At 118.1 km, on the north end of the lake, head left to Obing and Seeon. This, too, is a yellow road and in some places is quite narrow with sharp turns. Follow the signs to Seeon and, at 122.7 km, make a right across from a large farm. Beyond the lake on the left is Kloster St Lambert.
In the center of Seeon, turn right. To know where to turn, watch for a square white sign with a wide black band which bends to the right. These are often used to guide motorists through small towns. The black band indicates the direction of the main road; it may be straight, or curve left or right.
