My guess is that walking around a city or a forest is more helpful to creativity because of the gradual change in environment. And there is a lot of evidence environment has significant effects on thinking and behavior. Other studies have found high ceilings are good for creativity while low ceilings have a negative effect on creativity. I would imagine walking outside without any ceiling would be as good or better than a space with high ceilings.
