South Holston Dam Access provides a public boat ramp located a few miles downstream from the main dam on Highway 421, offering convenient water access for paddlers and anglers to South Holston Lake.

The gravel parking area accommodates multiple vehicles and includes basic facilities, with restroom amenities available at the nearby weir and visitor center.

This access point is popular for waterbird observation and serves as an alternative to the campground-only boat launch at Little Oak, making it ideal for day-use visitors.
