If you and your kids are Jurassic Park fans, this Texas state park is the place for you. For $5 or less, you can see some of the first Sauropod tracks ever discovered—they're approximately 113 million years old! Giant dinosaur statues lead the way to a riverbed dotted with the fossilized footprints.
The park also features campgrounds, backpacking sites, hiking trails and a playground. Guided tours are available—check the website for more information.
