Sun Mountain Road connects at the south end where the Jackson F. Kimbell State Recreation Area sits. This area has great campsites with direct access to the headwaters of Sun Creek. This campground is a great way to start or end your day's journey! Sun Mountain Road quickly climbs up the mountainside from the campground and levels off after Sun Pass. From there, it is basically a straight shot to the road's terminus, where it meets with The Dalles-California Highway. You need to be careful on the majority of this road. While it is straight and seemingly well-maintained, there are numerous dips and trees that can catch you off guard if you don't slow down. There are endless opportunities for dispersed camping in the area. Just be ready for mosquitoes!
