Wilkson is fairly easy route finding. Lots of Cairns. The entrance area is a big breakdown pile and you have to find a sketchy looking downclimb down an angled boulder chute to continue past the main entrance breakdown area. AFter that make your way to the stream level then climb out of it, following the rock cairns. Continue through the sketchy breakdown to a hands and knees crawl thats pretty wide and this leads you to the top of the big ole 500' long room. The guidebook tells you where to look for the horror hole drop. ITs a 2 bolt rig, Need a rope pad. 60' down is a double bolt rig to rig a rebelay while standing on a ledge. this also speeds the ascent process up as two people can climb at once out of the horror hole. when you get off rope and you are looking straight up the face of the drop, go to your right and climb past the big flowstone. Make your way across the top of a sketchy canyon riddled with whirl pool holes. ITs about a 30' fall into that lake obikechokee swamp that is int he guide book. Taking the topo canyon route bypasses having to rappel into the swampy mud, therefore you don't have to walk through it. You will come to some bolts to rig a 30' drop, then you continue down the crawlway and eventually will find bolts for the last pit, which is a sketchy rig. Have the tallest person rig it for ease ;)
Be prepared for 8-10 hours depending on the size of your group and the shape they are in.
Rumbling falls you have to get sign some WNS forms and liability forms through the park. I am actually trying to jump through the hoops for this same permit process right now but I keep getting people who don't have any clue.............ugh.
