Watch the sunlight dancing on the water as it flows over Yellow Branch Falls. Look out for any rainbows in the mist.
You're spoiled for sightseeing choice when visiting Mountain Rest. Yellow Branch Falls is a good place to kick off here, but there are numerous other fine spots to consider. Oconee State Park, Stumphouse Mountain Tunnel, and Oconee Station State Historic Site are close to the cascade of water and will fill in your day nicely.
