Specifically to the 190 section known as the Western Divide Highway, from M-50 north, right past the Trail of 100 Giants - huge Sequoias, this is a really nice, heavily treed and lightly traveled section of roadway in very good condition. It is a seasonal roadway, closed in winter. I did happen across a few deer, so be cautious, as usual. Some really nice camping spots along here. Some AMAZING slow speed, tight twisties north of the Quaking Aspen Campground. Just gorgeous.
Rising quickly as it moves into the forest, this road has a good selection of different types of corners.
