The mountains, fields and streams is the cliche, I would add derelict neglected industrial wastelands. Those were/are the places that I've always been happiest in. I used to think that it was because I was out in pursuit of game, and it was/is. But not until I stopped going the those place that I realised that it was not so much the hunting that I missed but the places themselves.
Ironically these days areas of outstanding natural beauty are fairly easily accessible, the neglected industrial wastelands seem to have gone and those were the places that were the happiest places to hunt. Wit
