How far out of Athens on 78? Is it a state park or private?

I tried a trail north of Dalonaga (sp?) on Wisenant (sp?) Mnt. It was great. $5 parking fee. It had several trails that went up the Mtn. Some rough parts. Some big mud holes. Fun, and you have to hose off your ATV/dirt bike, truck, and yourself before you get home. I saw a waterfall and several wildlife. Park ranger was very nice and helpful.
