OP, if you like Jasper area look into the Talking Rock area just south of Carter's Lake. It's rural as can be but everything you want within a 15 minute drive.
Also if the Ball Ground area is to your liking, but your wanting more rural, look into the Mica community off of Yellow Creek Rd. The community is easily reached from Ball Ground and in the northeastern corner of Cherokee bordering Pickens, Forsyth and Dawson Counties.
Finally the hidden undeveloped gem of Cherokee is on the north central side and it's a small community called Salacoa.
This place is situated in a
valley below Pine Log Mountain in Lake Arrowhead and borders Bartow, Pickens and Gordon Counties.
Salacoa is the one rural place in Cherokee that has remained almost the same, for the last 30 years. Large established farms, secluded sizeable lots of prime land and very few residential structures.
Access Salacoa via 140 out of Canton or 108 from 515 in Ball Ground. It's also accessible from Hwy 411 and Hwy 20 from Cartersville.

My family has lived in Ball Ground forever and I've resided there since the 80s. It has grown like crazy since getting the sewer system implemented, but has not lost it's small town charm.
Salacoa deserves a look, I'm thinking once you see it, you will be hooked.
