Ok, if you want to hit 78 to get there, take 78 to Nelsonville, north a bit on 33, to 278. Take that to 56, then West/North to 664. Slow it down past both Ash Cave on 56 and Hocking Hills on 664. Very low speed limit with bunches of pedestrians and cars on the road pulling in and out. (Parking on one side of the road, everything else on the other. People walking across the road everywhere.) There might be a ton of cager traffic in the way anyway. Especially on 664 between Logan and Hocking Hills state park. That's a decent ride. And if you go just past the 664 when on 56 at South Bloomingville, you find Jimbo's. Stop and eat biker food. Jimbo's Bar & Diner - more info » 23356 State Route 56, S Bloomingville, OH - (740) 332-6550 This is a typical bike loop and will have a ton of bikes on it. Actually, 56 is sometimes so much fun, I turn around and do it again. Alternate is to continue on 56 out of South Bloomingville to 180 to 374 and find your way over to 664. Be aware that 374 is a funky but fun road with some gravel and sand, and it goes past Cantwell Cliffs state park. There's two corners on 374 where bikes tend to go down. You can skip 374 and take 180 all the way back to 33 instead. Dang... now I want to go wit... edit: BTW, I've never heard of a bike going down going this direction, it's always the other way. Funny that...
