In Sept 2015 I stayed in Ouray for a few days and rode my motorbike through a number of passes in the area, including Imogene. The scenery was mostly spectacular and the jeep roads were, in places, interesting. I made videos of my rides and you can see them here https://www.venturacountytrails.org/...m#Colorado2015
. In the videos I clearly label all the trails so you know where I'm riding. I make them to show off the scenery and to show what the trails/roads are like. I hope they help you decide where to point your van. I'm looking to go back there myself once travel becomes a reality again. Have fun!
