I actually have a small above ground pool in my backyard. The only access to it is from my deck and it is gated off. The gate also has a padlock. My dck's are not allowed on my deck unless they are with me walking up the steps to the backdoor. Since I have two small children of my own (who are not allowed on the deck without me either), I have no worries about any child getting into my pool. I am super diligent when I'm outside with the kids, and no one is allowed to go off on their own at any time. I also have no toys near the pool so that climbing into any other way is not even possible. I just teach the kids that the deck is off limits, unless we are entering and exiting the house, and then I'm with them.
