On a weekday morning, it was peaceful and quiet (the only people there were other mums with kids). The park area is huge, with hills, ponds, statues (not to mention the Oberlaa pools, with separate entry - we did not have enough time to visit them). But you could spend an entire day at the park, on a picnic. There are a number of playgrounds for bigger and smaller kids (including some water channels with locks, which my son loved), there's a small cafe with ice cream, there are giant swings, a climbing wall, skateboard area...you name it.
