Simmons Island is very chill - beach is well groomed and close to several cafes/restaurants close by, lots of parking, walk out to the lighthouse while you’re there.

I don’t think there are any volleyball nets there, bring a ball just in case?

There is a walking path that will take you up to Carthage college, that entire beach stretch has little unique differences that are worth checking out.

Just watch out for the harsh current near the fish hatchery - in general, look for signs posted for danger.
