How Far are the Sandy Beaches from ATV riding area??? Or is people allow to stay in the lake shores of the ATV riding area? We are a big group and not everyone will be able to ride.

Not very far. I would suggest that you look at Google maps with the satellite layer turned on. As far as camping on the shore of the lake I have seen people do it but I don't know if it was legal. I would definitely check park rules beforehand. It is a fantastic place!

I don't know you should probably call their office. I can only give you directions on Google MAPS....
