If you want to see lots of gators, snakes, birds, and other local critters in their natural habitat, go to Shark Valley. There are literally gators sleeping in the parking lot. It's really cool. The tram is nice. For $20, you get a nice ride on the tram with a tour guide. Our guide was ok... maybe a bit too snarky, but the 15-mile ride is worth it. At the midpoint, you get 30 min to walk around and climb the observation tower. We had perfect weather and visibility. The tram stops whenever there is an interesting animal or plant, so you will get lots of good pictures. I think next time, I'd rent a bike to give me more time to soak in the views. The area looks a lot like a savannah or prairie. Big spaces, big sky, big gators.
