The City of Chandler just does it right...
I've been here a few times over the past several years whenever family comes into town. My most recent visit was with my two nephews who were visiting. This pool is one of the best I've experienced! It has a nice array of pools for different activities and age groups. Not to mention there was plenty of covered spots to sit if you aren't swimming. Do know that those spots get taken quickly, however, when it is hot out.
If you're looking for a great (and cheap) way to beat the AZ heat, this place does it!
