Stuttgart has the second largest Oktoberfest in all of Germany, and it is definitely more authentic than its more famous brother fest in Munich. I absolutely recommend a visit but once you've had your fill of beer and pretzels what's next on the Stuttgart tour? Here are a few of my reccomenations:
Patisserie Tarte & Törtchen
This is where I would recommend getting a coffee and a treat during your day of exploring...you will probably need the pick me up after all of your Oktoberfest craziness!
This library is beautiful and definitely Instagramable! Be sure to go up on the roof and check out the view while you're there!
Climbing to to the top of this tower might make you a bit sick (it moves a bit in the wind) but it's definitely worth it. And while you're there be sure to stick around and enjoy the lovely park.
Birkenkopf (aka Rubble Hill)
Birkenkopf, known as rubble hill in Stuttgart is a hill piled with the ruins from when over 45% of the city of Stuttgart was flattened during WWII. It is also a beautiful walk up to the top.
Kürbisausstellung Ludwigsburg-Pumpkin Fest
This is such a fun little festival, that runs around the Oktoberfest season. Stop by to enjoy some delicious pumpkin products and to check out all of the crazy art pieces made solely out of pumpkins.
Stop by and get a mocha (complete with a heaping scoop of chocolate mixed in) and learn a bit more of the story of Ritter Sport. You can also buy discounted chocolate here so be sure to load up!
Want a place where you can play like a kid? Check out sensapolis, this giant indoor park has a high ropes course, slides that track your speed as you race down them, and tons of places to play.
This place is magical. It's like drinking inside of a tree-fort. They also make their own whisky and liqueurs. Such a wonderful place for an evening drink with friends!
I hope that helps as you plan your post Oktoberfest adventures! Be sure to check out my Google Map for help finding the locations listed above:
