Hells Canyon Jet boat tours, Idaho

I grew up in Clarkston Washington, right across the river from Lewiston Idaho. It is only about 115 miles to Lewiston from CDI if you come down through Moscow Idaho. As far as a place to stay. Granite Lake RV park in Clarkston is very nice. We stay there when returning to class reunions. You can walk to Costco and Walmart from the RV park. The park is right on the river and bike path that runs for miles along the Snake River. I may be mistaken but I thought the jet boats loaded just down stream from Granite Lake RV park. You can call the Jet Boat companies and find out. I wouldn't do any of this without a reservation.
