Born and raised in Georgia, I never once heard of Georgia’s Little Grand Canyon. I learned about it from Roadtrippers.com — a website that points out cool places to visit along your road trip route.
In fact, it is in Lumpkin, Georgia — only about an hour and 15 minutes from the town I grew up in (Donalsonville, Georgia). After learning that, I found out my Dad had never visited either so we knew we had to take a road trip!
This little gem is considered one of the Seven Natural Wonders of Georgia. It was formed due to erosion — created by poor farming practices in the 1800’s.
The canyon is made of clay and other marine sediments and the contrasting white coloration is caused by water seeping over the clay. Throughout the canyon are crevasses worn away by erosion. You can explore these crevasses and will immediately notice a 10 to 20-degree cold temperature change.
The hike down is about three-quarters of a mile. They also have a 3 and 7 mile loop trail. Since my Dad is 82 years old, we figured the 1.5 mile round trip was plenty. We knew if you took the 7 mile loop, we would be rewarded with views of about a dozen rusty 1950s-era automobiles. Due to the environmental damage that removing the vehicles would cause, park officials have decided to leave them alone.
We decided not to do the long hike (we did not want to do that to my Dad), but here are some pictures I found that show them (thanks to Trover for these pictures):
