Ronald Reagan Presidential Library and Museum451

One of only twelve presidential libraries directed by the National Archives and Records Administration, the Ronald Reagan Presidential Library and Museum sits on a mountaintop with sweeping views out to the Pacific Ocean.

The museum offers a lifetime retrospective of Ronald Reagan, from college days to the White House, with presidential documents, photographs, and artifacts from his years in office.

Perhaps the biggest draw for children, though, is Air Force One. The plane which was retired in 2001 served as the Oval Office in the sky for seven presidents. Anyone who's ever wondered what it's like to ride on the world's most famous plane will want to take a peek.
