Not allowed in the pond and not recommended in the York River or Creek but we cannot prevent swimming there (we can only prevent or restrict swimming in bodies of water completely contained in a park). There is no real beach area.
Question is, why would you want to? It looks filthy.
No swimming is allowed
I don't know, we visited in January. The ranger's station there is really nice and the people very helpful; I'm sure you could call and ask.
