> A lake in the middle of a big city that you can simply get into is not a normal thing.
Stockholm is a big city (for European standards) in the middle of a lake. So, this is probably very difficult to emulate for other cities. Sadly around Sweden, trees that have been harvested for wood are replaced with low quality forest that do not meet biodiversity targets.

Parks are amazing and we should have more in our cities. I see people hiking and running in the forest all year round. Forests and nature are better than parks to bring a pace of mind and mindfulness that cannot be replaced by anything else. And they usually are free, so everybody can enjoy them independently of their economic situation. But each steps forward is a welcome step. And parks are also needed.
