Clifton is a large stretch of beach sectioned off into four areas (funnily enough, you'll see signs for Beach 3 3/4 as well, whatever that means). It can get pretty crowded over the summer, but overall it's a clean, quiet beach in a safe area. The water is not for swimming, unless you like ice cold water. But you can lie out in the sun and hail down one of the ice cream men for a sweet treat now and then.
I've seen people bring and set up volleyball nets. It can get really windy toward late afternoon, but during midday you can definitely bump a volleyball around.
There aren't really any eateries nearby (it's a residential area), so bring your own food if you plan to stay a while.
