Inflatable Pool Maintenance

What is a good type of pool if you want something that is low maintenance in terms of time and money?

I do not want an inflatable pool I filled with a garden hose:) I want a pool that does not have to spend a lot of time cleaning and changing filters, etc. I do not really matter a few hundred a year in maintenance costs (Although if I could do without it would be good), but I would like a pool that does not require much of my time to maintain and clean. I've heard of "salt water pools," but none of them. Any suggestions? Links would be great too.

Use the nearest natural body of water. No cleaning. No filter change. No maintenance. No charge. You can even pee on it whenever you want.
