Highlights of Vienna is a 10.3 mile moderately trafficked point-to-point trail located near the city of Vienna, Austria that offers scenic views and is rated as moderate. The trail is primarily used for walking and is accessible year-round.
On this tour you will see royal residences, the world’s most famous fine arts and a Gothic cathedral. On this tour you will see: Stephansdom (St. Stephen’s Cathedral, Hofburg Palace Complex, Trzesniewski restauarant,Schönbrunn Palace, Belvedere and Kärntnerstrasse. Although you will walk between most of the stops you will have to take U-Bahn between Trzesniewski restaurant and Schönbrunn Palace and Belvedere. Take U3 (orange) from Trzesniewski restaurant and Schönbrunn Palace (Stephansplatz stop to Johnstrasse). Take U4 (green) from Schönbrunn Palace and Belvedere (Schönbrunn stop to Karlsplatz).
Vienna is always worth a visit. My personal tip: visit the christmas market in front of the city hall, from mid Nov to Dec 23th.
BTW, the very first picture of this guide shows the parliament building in BUDAPEST, not Vienna!
