You will need to come down the mountain via a dirt road. The road is a bit rocky but not difficult. Any 2wd vehicle can make it both ways as long as it has good ground clearance. It is a one lane road so if there is a car going up while you are going down, you will have to work together to pass. Someone will have to pull to the side or back up. The bathrooms are in really bad shape so I recommend bringing a portable toilet. If you don't, be careful and bring extra TP. Aside from the restrooms, there is a lot to see. The river is very beautiful. For the campgrounds, they are nice and spacious. They are first come first serve and get filled quick at the Lumsden area. I'm not sure about the campground across the bridge. I counted about 11 vehicles down there on a Thursday.
