Below is an excerpt of the Land Between the Lakes map. Circled in red is Neville Bay, the location of the camp site. Camping at this spot is primitive but does have a nice single toilet house that’s free.
The road numbers are accurate. Once you turn off 100 onto 214, Neville bay is on the right before the road takes a sharp left uphill. You'll cross a few "bridges" with guardrails before getting to Neville Bay. There's a sign and an open path to the bay. It should be very hard to pass the campsite where everyone is. You can easily see it from 214.
Entering the park from North or South, you will pass an Info Center where you will need to stop and pay for your camping. It’s very cheap (3 day pass is only $7) and no wheeling needs to be paid for as the park is free to ride.
Here's a link to the website with all the info you should need.

Many of us will come in Friday afternoon and leave Sunday morning but others come anywhere in between that time. There are no set times for anything, no planned trail rides or sight seeing tours, no assigned camping, no one to tell you when you can or cant wheel, how loud you can be or when to go to bed. Show up at Neville Bay whenever you can and enjoy yourself. Now this goes without saying but I do expect for everyone to respect the park and the rules they have laid out and obviously respect each other. This park is huge with 1000s of acres of land to explore. Talk to folks and see who wants to do what. Some people want to play in mud holes, some want to sight see, some want to head to the gun range and fire off some rounds. Get in where you fit in.
