If you're traveling to the Everglades take a Crystal Seas kayaking tour.  You'll be able to paddle up mangrove covered streams that the motorized tours cannot access.  The guides are very friendly and they allow you to set your own pace.  Don't worry if you've never kayaked before just follow your guide's helpful tips and you're arms will last for hours.  Take the 6 hour or an over night tour, this will allow you to travel deeper into the park and see more wildlife.
