Children's entertainment park Kaiserwelt.. It is situated in 1 hour drive from Bad Reichenhall. Pay attention that the park is on the territory of Austria,but you can go through regional roads,so you don't need to buy a vignette, if you will come back the same road. Address of the parking: Brandstadl, 6351 Scheffau am Wilden Kaiser, Austria
Working time: from 19 May to 21 October from 9.00 until 17.00 o'clock (this time is indicated on the website, but in 2018, but to orient only). As i understood from the website, you need to pay only for lift: adults 21 euros, teenagers 16 euros, children 11 euros. (Maybe the prices are different now, there's information for 2018 on the website).
Google maps gave this address: Bromberg 37b, 6306 Söll, Austria but I can't answer the question if you can get here by car, I need to check the local navigators.
The park is situated in the mountains on the height of 1600 meters, the attractions here are rather simple, like our big playing complexes, there are water attractions, rides, climbs and a simple climbing wall. I think this park will be interesting for children under 10 years. Among the big advantages is that it is situated in the mountains, and while children wil be having fun on the playground, you will have an opportunity to enjoy the landscape.
There are places where you can have a snack, the restaurants are situated on the tops of the mountain.
I haven't been here yet, I hope to get there and enjoy the landscapes! )) Photo is from the website of the park
