Who needs special-effect theme-park rides when you can get the real thing at Yellowstone National Park? You'll see boiling hot water blast out of the ground, share the road with grizzly bears and bison, and visit a lake that makes its own rainstorms. Talk about a hot spot!
This huge swath of untamed wilderness, almost the size of Wyoming State, aims to please even the squirmiest travelers in your group. Watch their eyes grow big when the ground beneath them begins to gurgle, gush, and vent, when they spot a moose, elk, wolf, or buffalo in the wild -- just a few feet away.
