My husband and I are traveling to Europe from October 12-26. We are flying into Paris because we got a great deal, but we are wanting to spend most of our time between Austria & Slovenia and maybe 1-2 nights in Paris at the end of the trip. We are planning on flying into Vienna. We are really excited to see and enjoy the beauty of Austria and want to be active & outside (hiking, exploring, etc.) as much as possible (depending on weather), but also hope to visit some villages and some (possibly less) touristy parts of Austria in the cities. We don't have an exact itinerary in Austria yet and wanted some advice.
Some of the places we are hoping to see are: Salzburg, Vienna, Hallstatt, Wachau Valley, Lake Attersee, Tyrol, Langbathsee, Kaprun.
My question is if this is too much and if we can travel by train to and from these places or if we need a car. We are open to getting a car but it seems that most people recommend train for speed and expense. We definitely don't want to rush through all of these places but would love some knowledge on if some of these can be combined and how to enjoy Austria to the fullest in the week we have there before we head to Slovenia!
Any advice is much appreciated :)
