Hi all,
My girlfriend and I will be traveling to Europe for a little over two weeks in December. For some background, we're both in our early/mid-20s, I've never been to Europe before and she's been to some of our destinations but with her parents ten years ago. We like nature and hiking (for reasonably fit people, not exceptionally fit people), historical sites, cultural events, and food (that last one may be a given for everyone, but it's certainly a priority of mine).
In terms of budget, we're planning to lodge cheaply where available so we can allocate more to food and activities; we won't be especially big spenders but we do have some flexibility.
Our itinerary is as follows:
-Munich: arrival morning of December 11 to December 15
-Some combination of Bavarian Alps/Salzburg: December 16 to December 18
-Vienna: December 19 to December 22 (staying with friends)
-Prague: December 23 to December 27 morning departure (hostel already booked)
My questions primarily concern the Bavarian Alps/Salzburg period. We will be renting a car in Munich and have it available for this portion of the trip. Right now, we plan to do:
-December 16 (Wednesday): Fussen, Schloss Neuschwanstein, and Schloss Hohenschwangau
-December 17: in Berchtesgarden, some combination of the mountain, Lake Konigsee, the Echo Wall, and the Ice Cave
-December 18: Salzburg
The main omission that we considered is Zugspitze mountain and Partnachklamm gorge near Garmisch-Partenkirchen. They look phenomenal but I don't want to try to overschedule. Should we prioritize them over anything else in our itinerary, or did we make the right initial choices? Should we leave out a day in Munich or Vienna to do them? Would it be possible to combine Zugspitze & Neuschwanstein on the same day or would that be totally crazy?
We haven't yet booked lodging in Munich, but aim to do so ASAP before it's all booked. But before we can do that, we have to know when we're actually leaving Munich and where we're going! That's where you come in.
Thanks in advance for your help.
