Shark Valley, Everglades National Park, Florida You can ride a tram through Shark Valley for twenty bucks a head, or take advantage of that big senior discount and ride for nineteen bucks a head. We decided we would ride our bikes for free. It was only 15 miles, wildlife at every turn, a gorgeous day, and one of the primo bike trails in America. Where else can you watch a gator fight right at the bike rack. This whole river of grass area is awesome. I am so glad digital camera’s were invented. If I had to pay for development of all the photos I’m snapping, I would go broke. Everything in the swamp eats anything that doesn’t eat them first. If you go out early in the morning, you can witness the fittest surviving as the sun is rising. This is truly sucking the juice out of life.
