on the map you can see salzburg county in austria with salzburg city where mozart was born and the lungau region where I was born . . .
on the little map of austria I have also marked the city of Graz with an orange dot where I moved to over 10 years ago . . .
about 3 years ago my parents moved away too and are now in Burgenland county along the eastern border of austria so we don’t have a residence anywhere in salzburg anymore . . . Salzburg city surroundings feature some lakes whereas the Lungau region is mountainous great for summer hiking and winter sports with several snow resorts . . .

as for the city of salzburg it’s been ages since my last visit (I did the military service there even earlier) I always hoped for a taxi ride but only got customers to vienna in the 4 years as a taxi driver so far 
so I’m looking forward to checking out some of the touristy sights again too . . . a friend in salzburg and I are currently talking about a meet in salzburg, graz or both so I might finally do a salzburg visit again in a couple of weeks . . . so far and as far as I remember I can say the whole town is beautiful and perfect for a weekend or several days (for longer or permanent residence I prefer Graz) old part of the town along the river lots of nice old buildings and cafes for espresso great for walking around and you can also stop by and enter Mozart’s house in which he was born and lived! Salzburg castle on a hill can be visited also and overlooks the city . . . surely I could offer a couple of further suggestions on what to check out especially once my memory is refreshed by a visit in september 
summer time is running out fast so I would suggest either going there very soon too for sunny days in t-shirt or possibly waiting until december and make it a winter holiday salzburg in particular with all the then decoration and markets can be a beautiful city to visit especially around christmas time too . . .
