Quote from wiki.answers.com

Swimming is fun because it is completely different from any other sport out there. You swim in a completely different environment, the water, and you get a full body workout. Not only that, but it is more of an individual sport than a team sport. This is not necessarily a good thing to everyone, but I like to swim because I can work on improving individually. Swimming is also fun because of all the neat tricks you can do in the water. Plus, on a hot day, what would you rather do, than swim?
