There is a turn off on the road to Antelope lake. Left hand side of the road going up. It's big bike friendly and lots of places to explore.

One more thing I forgot. On the road up to Antelope lake, just past Genessee valley. There is usually an old lab sleeping in the road. Try not to run him over. He's not dead, it just looks like it.
