In Everglades National Park, be sure to take some of the ranger walks to view wildlife. Early mornings are best, or late afternoon even. Be sure to cover arms and legs and take mosquito repellent! If you're camping, you'll want lots of it! We also enjoyed the boat ride through the Everglades. I think the highlight of our Florida Keys visit was a snorkeling trip. We loved it so much; we did it twice! You might want to go to Key West while you're there. It's a fun place to visit, and you'll be at the Southernmost point of the US.
