Be sure to check out St. Martin an Der Weinstasse, one of the most picturesque of the the Wine villages. Burg Berwartstein or Trifels are interesting castles to visit. The view from the Cafe at the Kalmit overlook above Edenkoben is also cool. Try some Gimmeldingener Meerspinne and Deidesheimer Hofstück. Also try the Neuer Wein and Zwiebelkuchen at the many roadside stands. The fall colors in the vineyards and the Pfälzer Wald are great.
