What are the river beaches like?

Has anyone been out to Poplar Bluffs, Cranberry Flats or Paradise Beach recently? What's it like? For Poplar and Paradise, is it a pretty steep walk down, is the beach any good? For Cranberry, is there a big beach space? Hoping to go in the next few days but we have 3 kids and a lot of gear and we wonder what's the current state of the beach and if it's worth our while.

We don't swim in the river, we just play in the sand, have a picnic and enjoy the sun.
