If you don't mind the smell of manure this place is for you! We stayed in the Trout Point area, site 17. There are several camp sites located in this section of the park, most of which are big enough for a fifth wheel or TT. We had no issues with our 17.5 foot trailer. Site 17 has a small "beach" where we could launch our kayaks. Otherwise the shore is rocks and has a steep drop off into the river. There was a vaulted toilet, no other amenities. Fish were jumping all night. There are two entrances to the recreation area, one of which goes under a train trestle (11 feet clearance).  There were a lot of flies, which I guess is to be expected. Minimal amount of mosquitos. While it is BLM, it is $15 for overnight camping.
