So at City Beach, there were two little playgrounds.
The first one is quite pretty. There are some nice little bits to sit around, there's that rubbery flooring stuff, which is much less annoying to walk over than the usual sand, and it's all under lovely shade sails. However, the slide is not very slippery at all, and without being short enough to use the flying fox or any of the monkey bars, it isn't really very exciting play-equipment-wise.
The second little playground is un-shaded and has sand underneath. It has a cool little rock-climbing wall and a tunnel-thing. Both of the slides are non-slippery; the straight slide I actually got halfway down and stuck. There is some quite cool gym equipment next to it: if you live near this place, you'd be crazy to pay for a gym anytime the weather is decent, but alas our interest lies in the play equipment.
While the area is great, the playgrounds are not terribly exciting.
