This is an easy hike, but the view is well worth it! The main trail up to Anna Ruby falls is only about a half a mile one-way and it is paved, with some steps. The falls are definitely worth the hike! If you're more adventurous, there's a singletrack trail that continues on for about 5 more miles beyond the end of the pavement. There's a $2 access fee.
Drive from Helen, Georgia, through Unicoi State Park, and then you'll soon arrive at the Anna Ruby Falls Visitors Center.
