My cabin is in the Crossings community in Bloommery and no its not for rent, not allowed there. Check wvdnr website for float trips, there are a bunch. I have floated about 35 miles of it from cacpon bridge on rt 50 to Largent rt 9.
You can float and wade most of it. Great smallmouth from May to November. Gotta watch the river gauges cause it can shoot up quick. anything above 600cfs is tough to wade anything above 1000 cfs would be real tough to float and fish. Good access at the bridges, but all 60+ miles are private shoreline. I have camped on several properties just by looking up land owners and asking permission.
Best public access is probably the rt 127 bridge or the Bloomery access in near the crossings if you want canoe/kayak access without a full commitment of a float trip, you can wade and paddle upstream. Most float trips are full day length and you don't want to get it a boat under 250 cfs if you have some place to be (lots of dragging). It is one of the cleanest rivers in the state. This is a good resource for the science of it
https://www.cacaponinstitute.org/PDF/Publications/Portrait%20of%20a%20River.pdf It is your normal low gradient smallmouth river. Pool, riffle, pool riffle. Nothing over a class 2 unless you hit it at flood stage.
River is full of crayfish and helgramites. You can get 100 fish days, but probably average 14" bass. Got quite a few over the years over 18" and the occasional 20" fish. Pockets of largemouth can be found, lots of bluegill and rock bass, fall fish, carp. No cat fish, don't know why but there just aren't. I here Muskie like the Mouth of the cacapon where it hits the Potomac.
Due to all the rain this is the first year as far as i can remember that i didn't do aa floattrip.
