This is a nice park with roller rink where a lot of people play hockey, and tennis courts and the like. There's definitely some things that most parks don't have which make it unique. I will say however that the sand volleyball court (of which I play as much as I can), is very misplaced and doesn't have quite the fencing it should. It's probably a 3 ft fence that fences it from S. Town Center, when you can pretty much crush a volleyball and have it bounce into the street easily. Not sure if I'd want to bring my AVP ball at all.
Other than that, it's actually a pretty large area where a lot of people walk/jog and when I go after work, there's usually some sort of football or soccer practice. Never really paid attention, but I did see a lot of parents in chairs sitting along the edge of the field when I glanced that way.
In any case, it's one of many nice parks in the Summerlin area.
