From the Jones Creek Dam Trail (223E), take the fork to the right. This is a good bailout if you don't want to do any more climbing on the Jones Creek Dam Trail. There will still be a few ups and downs on this one, but nothing too bad.
This is where people get confused riding all of Moss Creek
Towards the end, you'll cross a road (Winding Stair Gap Rd.) and on the other side there is a makeshift campsite. There will be a short (a few hundred feet long) connector trail on that will put you out onto FS28-1 road. Take a sharp left and you'll see Lower Moss Creek Trail on your right.
take a left on Winding Stair for 1800' of uphill suffering.
