In reply to europebound:
I moved to Salzburg in October to live/work here long term, so I feel quite qualified to comment on (50%) of your question.
It is a very good place to be. As Casa Alfredino mentioned above, there are a huge stack of eastern alpine regions between 20minutes and 1.5hrs from the city. Why go over to Chamonix when you can climb all over the Austrian alps?
Obviously there is very little trad climbing, which I miss about the UK, but plenty of other cragging and lots of big mountain limestone routes, particularly in Berchtesgarden. In the winter ski touring is the primary activity here and you can drive to 100+ ski touring days within an hour of Salzburg. I also skiied a couple of times in my lunch break and did a few night tours after work too. My skiing has got a lot better, and I did some nice ski/mountaineering days out this winter including on Grossglockner.
Munich is better connected flight wise and slightly closer to Innsbruck, but otherwise I can't see too many benefits for going there re: mountains on the doorstep? I work 10km south of Salzburg and have a 2000m mountain (Untersberg) outside the window right now. If you don't like the idea of Berchtesgarden, Dachstein, Hohe Tauern, Hoch Konig and all the other big mountain locations next to Salzburg then its just over 2 hours to Triglav and was about 3 and a bit to Cortina/Dolomites when we went a few weeks ago. Have yet to venture too far west as haven't needed to! During the ski season there are a huge variety of mid-sized resorts and a couple of bigger ones too, the best being Saalbach and also Kitzsteinhorn for the glacier.
Couple of other points to consider:
1) There's a lot of klettersteig (via ferrata) around here too, if that's of interest. It wasn't much for me before, but they make nice days out as an alternative to hiking and some of the big ones are very physical. The nearest to my house in the city centre is around 1 minute walk from my front door.
2) Salzburg isn't a huge airport, but has regular and cheap weekend flights (friday/sunday evening) to London via Eurowings. I've had a LOT of friends take advantage of this to join me here for a weekend since moving out here.
3) The city is very beautiful. It has a big castle (one of Europe's largest) on a hill right in the centre, the river is great and it is a decent size without being too large and crowded.
4) Public transport is very good here. I cycle the 12km to work all on flat cycle paths down the river. The bus system works very nicely and with car hire at 70EUR/weekend when we need it, we haven't actually yet got around to buying a car.
Please message if you want to know any more or have specific questions!
