These are some of the hiking trails with the most unexpected natural wonders.
Providence Canyon State Park
This State Park is located just outside Lumpkin, GA. Known as the "Little Grand Canyon of the East coast" this natural wonder is spectacular multicolor clay layers exposed by erosion during the dust bowl era.
There are several hiking trails. The three mile White Blaze Trail circles along the rim of the canyon. Much of it is through thick forest so you have little view of the canyon until the last mile or so. Stick along the fence line for some spectacular views. There is also the seven mile Red Blaze Trail.
It requires a park permit and you will see little of the canyon until the last mile.
The canyon
There are nine "fingers" to the canyon. Entrance by way of the river for
1,2,3,4 and 5 and another small river for entering 6,7,8 and 9.
You can spend all day exploring.
Spring, before the Kudzu starts covering the views, would be the best time to visit this unique area.
