The Chattahoochee River originates in the mountains about five miles north of Helen. It flows through Georgia, forms the border with Alabama, and eventually changes its name as it flows into the Gulf of Mexico, near Pensacola. In this mountainous region, the river is best able to support trout. The water is cold, shallow, and is swift flowing at this point.
Just north of town you can fish from the banks of the river, or wade in the river and fish for trout in the deeper pools. As the river winds into town, there is a small park that gives access to the river. Many are the fish that are caught here. The state Department of Wildlife and Fisheries stocks the river on a regular basis at several points. This provides an enjoyable sport for the many anglers that come to this area.
One of the things for which you must be careful are the tubers. Three or four companies rent inner tubes for people to float down the river. In some of the narrow areas of the river you can get caught up with one of these tubes if you are not careful. As with any outdoor activity, you need to be aware of nature, itself. This area has a lot of rattlesnakes. If you go to an area that is not heavily travelled, the snakes like to lay in the sun on the warmer days. So, don't look under rocks and do other things that are unwise.
Overall, you will enjoy the day playing in the water... even if you don't catch any fish.
