The flying fox in this park is great fun for kids (and big Kids) and there's plenty of park land around the swing for kids to play.
Looking out over the bay and the iron cove bridge, the flying fox is a good 20metres or so long and being elevated at one end you get a good amount of speed up without having to run or push yourself.
There's coil springs at the end of the flying fox to slow you down and the kids generally end up getting about halfway back to the start after bouncing off the end.
The kids playground next to the flying fox has some great slides and skinny things to play in too. Definitely a great place to bring the kids.
