Are there any places to dock a pontoon and get off and let the family swim and just enjoy like a sand area or beach?

At the very end of the peninsula there are 3 docks to attach your pontoon. Too much moss and water plants to swim. No sand, but there are 2 areas that have swings, slides, etc.

There is no beach but there is a sand area with playground at the main docking and parking

Yes

Thanks everyone for the replies. We love the lake and will continue exploring and learning more about it. Happy boating!
