Penrith isn't the first place you think of when entertaining places are mentioned. Disney Land and other theme parks are probably higher up there. However, get some friends together; go for a drive along the M4, blast some songs and you'll be amazed at what you find. Along with Laser Tag, bowling, and a hell of a lot of Maccas, Penrith offers Aqua Golf. Not just normal golf, but Aqua Golf.
At Aqua Golf you lob the balls into a lake, of course attempting to hit the bullseye. It's a lot more fun than it sounds, even if you suck, and there's always the appeal of winning money if you hit a said bullseye. So if you have nothing better to do, and you're cruising around Penrith, try Aqua Golf. And if you find it's not for you, it's right next to the Penrith Panthers club.
