Yellowstone National Park
It's hard not to be impressed by all of the incredible natural wonders the world's first national park has to offer. Because an active volcano lies beneath Yellowstone National Park, the site has more than 10,000 hydrothermal features such as mudpots, hot springs and geysers — including the famous "Old Faithful." Plus, there are nearly 300 waterfalls and an incredible array of wildlife — including elk, moose, bison and bears — in this 3,472-square-mile park that straddles Wyoming, Montana and Idaho.
Although there are some hidden expenses to watch out for when visiting, it costs only $30 for a seven-day vehicle pass ($50 if you include a pass to nearby Grand Teton National Park). There are a few times during the year when entrance fees to all national parks are waived, however. And currently all fourth graders can visit national parks for free as part of the Every Kid in a Park program, making it a great family vacation idea.
