Sorry, my little girl grabbed my phone. Section 2, East Fork or West Fork for fishing. Section 3 has several tough rapids for fishing craft. Early in Section 3 is a small vertical drop that would be tough in a canoe or float.
You can drive all the way to the river at earls on the ga side.there is one river crossing you will have to do,and it can get up to the middle of your door at times.i have a tundra with a small lift and it only gets to the bumper. There are some pretty sweet campsites there. From what I understand you can camp anywhere on the river as long as a certain distance from river. But all the spots are actually right on it.
As far as ensuring you don't pass it. I always suggest scouting out the take out spots so you don't pass them. Sometimes even marking them with flagging tape or dropping a pin on ur phone.
