I prefer the Klamath over the Rogue.
Yeah, the water is brown, but I don't think it's any nastier than the Rogue.
It's a nice 2-3 day float.
Plenty of spots to put-in and take-out. Nice scenery, good camps. And there really isn't much traffic on the highway.
I don't think I've ever seen more than one or two other boats on any of my trips.
The water gets low, and slow by late summer.
And it can be HOT!!! down there. Was 112° in Somes Bar the day I took out a few years ago!!
You really need solid class IV+ skills to run the Upper Klamath.
The lower is mostly a class III river.
