In addition to swimming in lakes & rivers, AZ has many Swimming Holes http://www.swimmingholes.org/az.html Of course, you can't beat the 7, yes that's the number 7, pools in Sun City. They have very accommodating dressing areas with showers and hair dryers for the ladies. Each pool has a poolwalking area. I especially enjoy the indoor theraputic pool at the Sundial Rec Center and go there 3 days/week.
