Hello! My family is planning on travelling to Austria in September. We are really interested in staying in areas that are close to mountain playgrounds as we recently finished up a 3 week trip from Switzerland and the playgrounds near Grindelwald did not disappoint! So we are hoping for similar vibes.
We are thinking about a 2 week trip, would prefer public transport, and no big deal if we need to change locations however the main criteria is amazing playgrounds. Kids will be 3 and 4 at time of travel. Thank you!
Google "Spielplätze" (playgrounds) + the city / town you are looking for. I know of a set of furnished apartments in Vienna just around the corner from a good playground (Palais Brambilla). No views but it was a good place to stay with small children, around the corner from a Billa (supermaket chain) and down the street from a BIPA (Drogerie chain), with metro across the road.
Hope you find what you are after, I would probably look for places with views first and places with playgrounds second.

Maybe a little young yet for these...
WIDIs Heimat Spielplatz Hochoetz. Don't bother with the Ötzi-Dorf. Old expensive and not much to see. I like the Kühtaile Alm too.

I'll just add this for fun. Getting there with public transportation would be challenging and it's out in the middle of nowhere. Heidi Alm

I would Google the term "bergspielplatz österreich," which translates to mountain playground Austria. You then get many ideas, obviously in German, but you can easily translate to English.
As a personal recommendation, we thought the playground in Seefeld at the top of the mountain was great.
