This old town, along the east bank of the Mosel, is best known for its excellent wine, Schwarze Katze ("Black Cat"). The grape is king here, as you'll quickly realize if you visit during the annual autumn wine festival. Nearby, on the left bank of the Mosel, 8km (5 miles) from Zell, stands the little wine village of Alf. The surroundings are idyllic, especially if you climb up to the Marienburg, which has a fine view over the Mosel and the vineyards of Zell.
