We found 18 water parks within 150km of Berlin. Of course Jari and I couldn't visit and review them all - we have only been to 2 of these yet. So we used our well-proven method and compared all online reviews from several popular websites - and created an aggregated review score.
As most of these water parks are far outside of Berlin, we also checked how long it will take to get there. We always used Alexanderplatz as a starting point.
From all the places we have analysed, here are our top 5 picks based on distance, review score, and excitement level.
Our Top 5 Picks
Spreewelten Bad Lübbenau
nice water park with an average score of 4.14 stars (out of 5) only downside is that it's far away with 1:10h drive from Alex . But it's also relatively easy to reach by train (1:16h).
nice water park with an average score of 4.03 stars (out of 5) only downside is that it's far away with 1:15h drive from Alex and impossible to reach with train.
probably the most popular water park, and definitely the most impressive an unique. Make sure you don't go on crowded weekends or holidays. average score of 3.93 stars (out of 5) and 0:50h drive from Alex. This one can also be reached by train in 1:20h
this is more like a indoor swimming pool with a slide than a water park. But it has the third best ratings from all water parks we reviewed with an average score of 4.15 (out of 5.0). Its also not so far away if you have a car: only 35 minute drive from Alex. And if you live in the south-east of Berlin its even closer.
Aqua Stadtbad Hennigsdorf
this is more like a swimming pool with a slide than a water park. But it has the second best ratings from all water parks we reviewed with an average score of 4.17 (out of 5.0). Its also not so far away if you have a car: only 35 minute drive from Alex. And if you live in the north-west of Berlin its even closer.

Places we would not recommend
Blue Potsdam has the worst ratings of all water parks we reviewed with an average score of 3.00 . People complain about high cost, long lines, bad food, broken equipment.
Stadtbad Lankewitz and Wellenbad am Spreewaldplatz both are conveniently inside of Berlin. They are also both reasonable priced. But our guess is that the negative reviews (3.56 and 3.37) come from the lack of main attractions and crowds of people.
Freizeitbad Schwapp looks amazing on the pictures, but reviews are mixed and negative (3.58) . Ticket price of 20 € / adult are also hefty.
