Please follow always the signs "Altstadt" whenever you come into a city. "Altstadt" guides you to the old downtown. If you do not so you miss everything interesting!
I found parking close to downtown. Unfortunately the allowed parking time was very limited and I had to rush. Don't make the same mistake. Find a better place to park.
We recommend that you first visit the "Kurverwaltung" where you can collect some information about the attractions of Bad Berka.
I am not a fanatic in following all the steps of famous people of the past. But for those who are - Thuringia offers a great deal. Bad Berka for example is very proud that Johann Wolfgang von Goethe had spent some time here.
I just strolled around, took some pictures, admired how nicely everything looked. I think I was the only visitor at this time and also the local people were hiding somewhere.
But I liked the little town and regretted that I could not enjoy a nice bowl of ice cream.

The village was mentioned the first time in 1119 which means it had along time to grow.
It was a pleasure to walk through the old town. As already mentioned I only saw a few local people and no tourists.
Most of the houses had been renovated. I am always amazed what has been achieved since the reunification of Germany. The majority of East and West Germans accept this, but a few wish the old times back, similar to Russia. What can you do against that stupidity?
Bad Berka does not have a wellness center with spa. However they offer treatments against digestion problems by drinking water from a special well. (Goethebrunnen) Please ask for detailed information at the "Kurzentrum".
Bad Berka is certainly another place where I would love to stay to explore the surrounding area.
You may get better rates and do not have the stress of finding always a new accommodation and packing and unpacking.
