Hello! I have always wanted to visit at least one Christmas market in either Germany or Austria, but there are so many options that it's very hard to narrow down where to actually go. I'm looking to see if anyone has any recommendations of particularly good ones, or ones that aren't as nice or aren't worth it.
I have already been to Berlin, Dresden, Freiburg im Breisgau, Salzburg, Linz, Graz and Vienna, and I have spent the best part of a day in Munich for Oktoberfest but haven't actually stayed there. I am open to returning to any of these (particularly the big centres like Berlin, Vienna and Munich) if their markets are particularly recommended, but I am mainly trying to find places I haven't already been. I'm open to Nuremberg, though I'm a bit hesitant since I plan to spend a chunk of time there anyway at some point once their rally grounds documentation centre is back open, and I don't necessarily want to combine a fun Christmas markets trip with a sobering history trip.
I speak some German, so I'm open to places that are off the beaten track a little where English might not be so universal. I'm also open to staying in one home base and then venturing to a few different local towns/villages by train (but I would never want to hire a car). I don't mind overnighting in a couple of different locations, but I don't like the sort of itinerary where you're packing up and moving to a different hotel in a different city every couple of days. It would also be nice to be in a place where the Christmas markets aren't the only thing to do, and that is lovely to just hang out in anyway even if you're not at a market. And while I don't mind other tourists, and of course any large Christmas market is going to attract a lot of visitors, I'd rather avoid places that are so mobbed with tourists that it rather ruins the experience and feels quite inauthentic.
On a bit of a tangent, I was looking into Rothenburg ob der Tauber, but it looks like it's in such an out-of-the-way location rail-wise that if you were there, you would pretty much be going only there - it's not easy to use it as a base to explore multiple different festive towns and cities (as far as I can tell, you need three different trains to get from there to Nuremberg, for example). Has anyone been to Rothenburg in the winter - is it worth going there for its market? Is there enough going for it that you can spend a few days just in Rothenburg without getting a bit bored, or is it frankly more of a day-trip destination?
Thank you in advance; any advice is very appreciated. :)
