My brother in law who lives in Naturita has been driving up to the lake in his little Kia. Now with the recent snow that may not be a possibility but he would certainly do it in his old Ford Truck. I would think a 4x4 could make it without any problems. The roads are usually pretty beaten down (ie….the farmers still make the trek back and forth each day). If you aren't certain then call the ranger station there in Norwood.
