From A23 (Hamburg-Husum/Heide) exit at `Meldorf` and follow the signs to Meldorf. Drive through Meldorf until you come to a traffic light with a T-junction. Turn left here and turn right at the next chance. Follow the road until it makes a big curve and you see some silos, here is a sign for `Speicherkoog` where you turn left. Follow this road all the way until you see a lake to your right, turn right and drive all the way to the dam. Follow the curve and to the right you have the parking lot. Walk over the dam and see the bay.
