Need to Know
This trail is poorly maintained. There are many portions that are overgrown with thorn bushes that will tear up your legs. The trails are washed out many times—they have become creek beds due to the lack of drainage on the sides of the trail. The washed out portions are full of baseball to cantaloupe sized rocks that are hidden by dead leaves.
I also came across no fewer than 15 logs across the trail that were too large to clear with the axe that I brought with me. I will not be coming back to this trail on a bike. Maybe on foot.
Starting from the trailhead, you enter the Yellow Loop by crossing the dirt road to the immediate west. It starts off fairly level, and ends up before the split in a very low area where the trail and the creekbed are one in the same. You'll exit the wet area by going up some extremely steep hills.
Stay left at the split and you'll cross Highway K and see a small camping area with a clearing and a firepit. You'll see a pond, and follow around the pond counter clockwise. At this point, you'll want to stay to the right (close to the pond) and not take the wide flat trail to the left, which takes you west to Highway AC. Watch for the marker carefully.
From here, you go down some easy hills, but will end up going back up some steep hills right before you get close to Highway K again. About halfway down the east side (returning to the split) you'll hit some very steep hills with loose rocks, mud, and leaves. Unless you're very skilled, you'll probably need to dismount and walk up those hills. Once you get back to the split, you'll stay to the left and head back east towards the trailhead.
