After spending 10 days in Switzerland, we decided to end our two week trip in Vienna, Austria - which happened to be both my boyfriend and dad's favorite destination of the entire vacation.
Vienna struck the rare combination of being a culturally rich and strikingly beautiful city. You can make it both an active trip (walking tours, lots of steps) and a culture-focused trip (sightseeing, exploring the many museums and the history of the Habsburgs).
Lastly, the city has such amazing bars and restaurants - we always had the best dinners to end our long and active days!
