You'll need $5 (2018) or a state parks pass for parking.
This is the easier of two routes from the very touristy, German-themed village of Helen into the center of Smithgall Woods State Park. There are a couple of wildlife openings - I saw some turkeys. There is a ford through Duke's Creek just before you reach Tsalaki Road
. Other than that this is an unremarkable forest road.
There is no vehicular traffic allowed on any of the roads in the park.
