A small town located southwest from Denver, I have heard it many times that tourist go there to fish and take pictures of the hills and the thick forest.
If you would like a nearby trip to a local place not far from Denver, you can consider Deckers. It's not flashy like some other places, just nature.
The town has one general store and a few shops where tourists get their needs when they are done exploring and fishing. I don't know much about this place but my friend does. He's been here and he promises to come with me next week.
