Can the public, not camping, pay a fee and use the pool?

Yes

The pool is for JCC residents...and there is a fee, just like upper county park. Visit the JCC Web site for prices. .. There is an annual fee, not sure about a daily fee

Why is it, when you ask a simple question, there is always that one person who has to respond with a smart answer? FYI I swim in the river with the big fish but during the week when I can't take my grandchildren, who will be visiting out in the boat, I am just trying to see what my options are. Thank you!
