We took several walking tours, including one of Art Nouveau and one of Jewish Budapest. Both were led by guides of truly outstanding backgrounds, and both tours were marvelously interesting. We are history buffs, and both tours helped us to understand the complicated backgrounds of the areas we were walking through. The Are nouveau tour was gorgeous, of course, Budapest being the find=est city to display that art form. The Jewish tour was in-depth. All I can say is: Give yourself a major treat and take both of these tours.
