Divide Ridge is a rough dirt road with very little difficulty aside from some tight branches right near the end. You'll have great views of the mountains as you traverse near the ridgeline of the mountain, culminating slightly down in a valley with a secluded campsite with plenty of space for a group of people.
This trail had a few camp spots along the way up, with several potential camping offshoots as well, so finding a spot to stay the night shouldn't take much effort!
