This unique attraction in Texas is not the place to go if you want to see wild animals in their natural habitat, but it is one of the best places in the U.S. to get an African safari experience. Fossil Rim covers about 1,700 acres and is home to 60 species of exotic animals, all of which roam freely. The residents of this fenceless zoo include giraffes, gazelles, zebras, rhinos and cheetahs. No, these animals are not Texas natives, so the magic might not be there for people who are seeking something totally authentic. At the same time, a Fossil Rim trip is a far more immersive experience than a standard zoo could provide. Fossil Rim, founded by a Texas oil man, is involved in conservation efforts around the world.
