Second this. It's often overlooked. Driving the main loop is probably only a 2 hour endeavor, but allowing a full day to do some of the (relativley) short hikes in the park is well worth it. The Devil's Kitchen trail in particular is super cool, about 1.5 miles round trip with a few spots with ladders and interesting scrambles. It's super memorable and up there with some of the best hikes you'd find around the region.Check out the Colorado National Monument near grand junction. It's incredible.
Not sure if it's your thing either, but there are some great vineyards in the Fruita and Palisade area just east of Grand Junction, especially for red wine. I can send a few suggestions if you'd want.
