Hells Canyon Resort RV Park...it is on the Snake River, large sites, easy access, no height obstacles, paved sites. It is just off Hwy 12 at the west end of Clarkston, WA
509.758.6963 hellscanyon.net.....1560 Port Dr Clarkston, WA
Granite Lake, also on the Snake River & Clearwater River. Right behind Costco. 509.751.1635
Hells Gate State Park on the Snake River. Lots of trees and shade, walking paths, but, unless they do some tree trimming I am a bit concerned with some low hanging branches, not large put still.
Lewiston Elks Lodge 896 if you are an Elk member. Water and 30 amp only, but there is a dump station close at Hells Gate State Park, easy in and out. Elks has a lot of pedestals but the layout is a bit strange. I know, I am an Elk member
If you go to Hells Canyon Resort, stay in right lane at the bottom of Lewiston hill and bear right at the rose garden, huge American flag. Right at the stop sign, 128, follow that to the Red Wolf Bridge, only bridge, and take a left, at, the bottom of the bridge take a right and the rv park is right there. They have major road construction going into Lewiston on Hwy 12. Also same route if you go to Granite Lake RV, when you take the right at the end of the bridge stay on that, one stop sign, and just past Walmart before the Costco building take a left, will take you to Granite lake.
Hope this helps a bit.
