Not even close to each other. The park is off RT. 4 near the power plant ... several miles drive from Solomon's Island and the tiki bar. The bar is definitely a good place to party though if you don't mind being right next to the road. I stopped going there years ago because the owner was a biatch and we did not get along at all. Heard the place changed hands so I might have to go back

If you wanted to drive that far south though, I would go to Point Lookout instead. Much nicer
