Three important take-aways!
1. DO NOT take the Google recommended route (fastest route) where you turn at Lenore Grade. It turns into a very narrow, GRAVEL road, horrible for RV's! If coming from the West (like Lewiston), take the route to Juliaetta and Kindrick (Hwy 3). It is only about 10 minutes longer, paved the entire way and is easier on your rigs.
2. You should download and print directions, as you will lose internet service shortly after turning off of HYW 12.
3. The last 20 minutes becomes a very steep, very narrow road with tight switch-backs (one-lane priority for RV's and big trucks). Be sure your brakes are good before you take this trip.
We were fortunate to stay in the best loop - Kokanne- (privacy, nice spaces and very pretty). The other loops had less privacy and were a bit noisier. The beach area for swimming is extremely muddy and not much fun. We made the best of it but would have had much more fun had we been in a boat. The rangers and other camp staff were extremely nice and helpful and it was really beautiful. I think if we had taken a boat and taken the easier route, our experience would have been a 4!
