At the end of the Wilderness Camp road you will find Wilderness Camps (imagine that). Stop at the check in point, the website says boaters will be charged for use of the road and put in but I have never been, just buy a muffin or cookie from them and they are usually happy. If you hike about 150 yards up river from where the people at the check in tell you to park you can catch a small warmup rapid. If you put on in Kingfield appartently there is one more rapid you can catch called "Rams Head". Apparently this is an excellent surf spot but I have never thought all the extra flat water was worth the play.
