Short break Switzerland, Germany, Austria or Italy - ideas please!

[WatermelonKiwi]

Looking to go away for 5 days at the beginning of September with DH and DS4. We’ve done a beach holiday this year so fancy something a bit different. Can anyone recommend anywhere that’s easy to go to but has sufficient shops/restaurants to mean that we don’t need to venture too far during the week? Not looking to hire a car. Wanting something with some nice scenery and a chilled vibe!

Thank you!

Engelberg near Lucerne in Switzerland. Walks, lifts, cheesemaking monastery, glacier with revolving cablecar.
Arosa -family friendly walks, Lifts, animals, high ropes climbing course

Kaprun or Zell am See in Austria are nice. Lots of swimming lakes and nice restaurants.

Vote 2 for Engelberg- get a Swiss pass train ticket. Valid on all public transport, some cable cars and boats. Easy trip from Zurich Airport. For your child get a Junior card on arrival and then their travel is free as long as they travel with you or DH and you have paid the 30chf fee
My only caveat is that the weather is September can be great or so so/some rain. So I would consider somewhere like Rapperswil in Switzerland. It’s at the top of lake Zurich. Very pretty town. Walkable. Nice walks by the lake and over a very old long wooden bridge which goes over the lake. Has a small castle, rose garden, deer park and small zoo which is v famous in Switzerland. Good transportation links to Zurich (which is in no way a big city) and to St Gallen. So if the weather isn’t good you have the museums of those cities. There is also a water park called Alpa Mare near by that is a lot of fun. You could take a boat trip.
Its a very chilled town on the lake and very pretty. At the Marina there is fantastic selection of resturants as well. Plus a couple of supermarkets.

Zell am See or Saalbach-Hinterglemm in Austria - about 90 mins from Salzburg airport using free public transport and plenty to do in and around both towns. Innsbruck is similar and also has direct flights from London.

Bodensee/Lake Constance in Germany - fly to Friedrichshafen (Easyjet)

Aosta would fit the bill. It has a train station, cable cars into the mountains, hiking trails, an adventure park, Roman ruins, loads of fantastic restaurants serving local cuisine and good shopping. You'll be right by Monte Bianco and the Matterhorn so the scenery is amazing. You can also easily skip over the border to Chamonix and Courmayeur in France. Aosta town is impossibly pretty and historic too.

I like @Havanananana's suggestion:

"Innsbruck is similar and also has direct flights from London."

I've been, and am reminded I must go back as it's wonderful.

The town's full of great architecture and historical stuff, if that interests you. Swarovski crystal place and big ski jump also nearby, which we didn't visit but could be fun. Just the river Inn running through the valley, with its clear water and glorious scenery around would all make a great short break.
