America celebrated the 102nd anniversary of the National Park Service in 2018. Famously called "America's best idea" by the novelist and historian Wallace Stegner, the national park system offers families a wonderfully affordable way to visit America's most cherished and beautiful landscapes, view wildlife in their natural habitat, learn about geological and cultural history, and appreciate the great outdoors. 

Visitors flock to national parks in huge numbers, with the total number of visitors topping 318 million in 2018.

If you plan to visit multiple parks in a 12-month period, it might be less expensive to buy a National Parks Annual Pass for $80.

The National Park Service's Find a Park tool is a wonderful planning device for locating parks, scenic trails, battlefields, and other treasures near your home or along your road trip route.

Before you go, explore the National Park Service's WebRangers site for kids, no matter which park you plan to visit. ​Junior Ranger programs are available at the parks. Details differ depending on the park, so check what's happening at the park you plan to visit before you go.
