This is another loop that branches off from Thunder Road. Unlike many "loops" in the park, this one leaves from and returns to the same place on Thunder Road. If you do Thunder Road then you'll probably do this loop on accident as I did. It isn't really that well marked but you'll realize it about the third time you go across the same set of roots. It flows really well though so it's not bad, and if you finally figure it out, you can make a quick step over to Thunder Road.
