Paradise Island is another one of those "blink and you'll miss it" causeway islands, appearing on your way out of Pasadena towards Treasure Island. On your way you also pass two other islands called, somewhat unsatisyingly, the South Causeway Isles. (Or, if you prefer, "Yacht Club Estates", which is the name of the gated community that occupies them.)
I've never actually gotten out of the car and walked around here. I don't even know if there are parking places for an uncouth outsider like me anyway. But it's enough to drive around on it, or even just to pass it by quickly on my way to Sunset Beach.
