Nice places for a walk: the forest, a river bank, a park, walkable (zero car) city center. Poor places for a walk: anywhere there are cars, anywhere that is indoors. I get that there are places with inhospitable climate where it's too hot even in a shady forest or too cold even with the right clothes. Those places just don't have truly nice places for a walk.
