National parks across the country can provide thrilling vacation opportunities for families. Take Yellowstone, for example. There's the excitement of waiting for Old Faithful to blow, and the thrill of exploring the park's other geothermal features. Families can travel around the grounds on horseback or take day hikes into the backcountry, where there are opportunities for wildlife sightings. In some instances, however, Yellowstone's bolder wildlife will come find you, and you'll have to be careful they don't wander too close.
At Yosemite, another of the great national parks, families can tour groves of giant sequoias, and if little legs get tired, a tram tour traverses the steeper terrain. (If anyone in your family has impaired mobility, arrangements can be made to drive your vehicle behind the tram.) In the rest of the park, stark rock formations and shimmering waterfalls are sure to have everyone reaching for a camera.
And that's just two of the close to 400 national parks across the United States; there are all sorts of opportunities out there -- many within easy driving distance.
