Stayed at Kamp Klamath for 6 weeks back in the fall of 2015. Fished the mouth once, that was enough for me. Fished the Glen several times but with all the flossers it wasn't a place for fly fishing. Really spent more time fishing for perch in the surf than anything. We loved the park! Watched the bears in the evening by the fish cleaning table and those BBQ's were always fun and well attended.
My wife made good friends with "Zee" the goat, she fed him carrots & such every day. He was a good old guy but the day before we left a big cat got ahold of him and killed him. The wife was devastated. Aron the owner is a really nice guy.
The one faults I could find was "MOSQUITOES" and no real access to the river from the park unless you were up to thick undergrowth, Poison Oak, swampy ground. The park changed significantly during the high water years!
Another place I can safely recommend. No noise, no intrusive neighbors. Just nature, your fishing rods (or rifle scopes!) and you. :)
