I rode with Bill R. up there and we stayed at Young's Bay Resort's campground. Website says $25. They have a pretty scenic view across their marina. There's a restaurant/bar up there next to the premises. https://goo.gl/maps/9PPbvraer5w
There's another place with cabins, but they're $150/night for 2 people. And unless you're fishing and boating, there isn't much else to do.
