Awesome place! I'm sure you'll enjoy your time there. Wish I could make it. Going to head out to SNP next weekend. Working this one.
Heading South you go into the roller coaster section. The creeks are probably over full and almost impassable with all this ran/flooding we've had. Still, you ought to be able to enjoy a little hike on the AT. There's another blue blaze trail there as well, if I remember. Never hiked it, not sure how long or where it goes. Hopefully you'll give us a trip report and cover that!
