The Sommerbad in Pankow is open from May until September and is a great place (if you get there early in the day) for toddlers and children. There are changing rooms etc at the top of the roped off step area. There is also a big refreshment outlet.
There is a large area of parkland as part of the complex for sunbathing and picnicking. Also nude sunbathing!
The pool can get very busy and a bit rowdy in the afternoon and in the holidays so perhaps a morning visit would be better with small children. We usually go at about 9.30am for an hour or so and as we are leaving the crowds are arriving. Out of school holiday times it is less busy.
