the commercial companies allow five year olds to go on this section. also allow customers to paddle duckies by themselves. if you have any whitewater experience at all, you will be fine. you probably won't even get wet in a raft. however, this section is usually done as a day trip at higher water levels. if the water is low, it could be done as a two day. going on to cunard would be a good call to make the trip about three or four miles longer.
stone cliff and thurmond are basically the same. there is about a mile of pretty much flat water between thurmond and stone cliff. the public access is at stone cliff. i don't think there is public access at thurmond anymore.
glade creek is a creek on the river left side of the river several miles upriver from prince/mccreery. i really don't think there is any access at glade creek, but i could be wrong. it's been about ten years since i was living in wv. you can go up to where route 64 crosses the new and then drive down the river right side to a put in called meadow creek. from there it is probably ten miles to mccreery/prince.
as boat-ers said, rudy's is a fun rapid, but it is after the stonecliff/thurmond take out. if the water is low watch out below rudy's. there is a bunch of nasty looking metal sticking out of the water. i believe it was an old train that somehow ended up in the river.
there is a good campsite below silo rapids on the left. don't camp any farther down river than silo rapids unless you are going on to cunard. if you go on to cunard then you can camp below thurmond where there is no road access. the road into thurmond runs up the river left side and then crosses a bridge to the right side and goes up further to thayer. thayer is a little "town" on the river right. there are a few houses there. it is in the middle of one of the longest pools on this section, and other than the railroad tracks, will be some of the only signs of civilization on this stretch. after that pool the river will start turning to the left. the next major rapid is silo.
the local rednecks like to come down to the river for some car camping, drinking, and fishing. some of the beaches with road access below silo rapids and above thurmond are completely trashed with broken beer bottles and various other garbage. not to mention the drunken rednecks stumbling through your campsite in the middle of the night.
btw, i would definitely bring the sit on top.
i don't know if anyone is running a shuttle service there. you might get more local info from boatertalk. most people on mt. buzz are in colorado and not that well versed with class 2-3 sections of water in wv.
