Headed east to the Fayetteville area, we were looking for a place to stop for the night along I-40 between Knoxville and Asheville. We found Little Big Creek Horse Camp on google. It's 2 miles off 40, they have power (120v), covered tie stalls (we staked out) water for horses, a covered picnic area, fire pit, and vault toilet. They were in the process of replacing their fencing. The gate is giant but because of the amount of rain they've had, we decided to back in so I didn't risk getting stuck turning around. They rent to one party at a time, so no one else was on site. $15/night. You can find them on FB. It's rustic, but very functional. If it was warmer out, it would be an awesome place to leave windows open and have the sound of the river lul you to sleep. We hear there's excellent trails nearby but we didn't have time to ride.
