Basically everything RED is worth seeing.
MUST SEE areas IMO
The Jungle - 4 ways in or out, multiple lines, completely different experience on how you navigate through it.
14/15 (The mOoN/ Devil Woman) Fun trails with multiple lines and can be ran both directions, I'd say full size friendly (you have to go through cattle gates to get over to 14, just open and close them behind you), OR you can go up 61 (Copperhead Rd), cool ledge climbing then a neat big rock garden on top.
the top of 5 (#5 Area/CrackHead/convergence of 4-5-70-71), LTS of rock, cool cedar thicket up top with basically no dirt, looks like something you'd see out west.
32/13 (Honey Bee, Stinger, and Razorback) are some of the first rock trails in the park, 13 is good crawling, a bunch of lines, full size friendly.
4 (Big Head Rock) where it starts off of trail 1 is a good place to gather and watch/play.
63 is one of the newer trails, no "BIG" obstacles, but a fun lite crawl. The first (red) part of 63 is long steep hill with some ledges, if you can't make that, 43 is an alternate entrance (with better crawling)
Basically there is good crawling every where you turn, you can either hit the crawling back to back to back, or string it out and ride back and forth to the different areas of the park on either mild trails or just jump out on the gravel road and pass though camp on your way
