Section 3 is a beautiful section of river. Since the Chattooga is a
National Wild and Scenic River the river corridor is protected by a 1/4 to 1/2 mile buffer zone where development is not allowed. There are few permanent signs of humans from the route 28 bridge to route 76 bridge. You may see tents and a campsite or two but no roads, houses, convenience stores, or fast food restaurants.
The access points (other than those at the bridges) are set back 1/4 mile or further from the river so that you will have to carry your boat for a while. There is a self-permit system (no fee), where you fill out the form, drop a copy at the box near the put-in and carry the other copy with you down the river.
