There are a ton of playgrounds in the county. The trick in Florida is to find one that has some shade or only visit them at the end of the day. Yes, I remember going down the metal slides at the playgrounds during my youth and feeling the blistering sting of the heat. You can choose to subject your children to this, but if you want a slide that won't create blisters on your backside, then head to the County website and find one that is close to you. Upper Tampa Bay Park is a good choice and so is Skyway Park.
