I have been going to this RV park for years and years. While it is not fancy, it is clean and access to the river is a short walk. It's closer than the 500 yards mentioned by others. There is a great salmon hole out back called Turtle Rock. We have pulled many 20+ pound salmon here, right out back of your camp site. Great wildlife, scenery, and it is very quiet. If you are looking for a basic, clean spot to stay for a while, this is it. We camped here in a Motorhome.
This campground claims to be on the river but it most definitely is not. You have to walk a good 500 yards to be near the river (across a street) and even when you get to the river the access is NOT good. You can hardly even get to the water. The owners are very nice people- but I wouldn't recommend staying here for more than a night if you just need a place to rest. They have good shade here, but there are a number of people staying in this park that appear to be full time residents. If you're OK with just a nice shady area with grass, then this place is OK. We camped here in a Fifth Wheel.
We have been staying at this park for over 10 years and plan to continue each October. Nice, clean park that is well maintained. The park is about 100' from the Klamath River and fishing for Steelhead & Salmon is fantastic (in season). There are fishing guides that stay in the park and are available for drift fishing on the Klamath River. During fishing season, reservations are recommended! We camped here in a Fifth Wheel.
