Mountain vacation recommendations

[I make oil]

I’m looking for mountain vacation ideas. I usually like Tennessee. Especially the area around the Smokies; Gatlinburg, Townsend and Pigeon Forge. We go there once or twice a year. Last year my bride decided she wanted to see different mountains so we went to Montana. That was nice but the drive up was brutal. I guess we could fly but I'm really don't care to go back there this soon.

Right now we are thinking somewhere in Colorado. Maybe Boulder? We like to see the natural sights and hike along with doing city stuff. I also enjoy trout fishing if available. I will bring my fly rod. My son Hunter is going to Costa Rica with friends July 18th thru the 25th so we are going to head out the day after the Salty Cajun tournament for a week while he is gone. I prefer to rent a cabin over a condo. Any recommendations?
