National Parks At a Click
Save this site. With one key stroke, it will take you to the latest official information on the National Park Service's 388 sites.
Known as the "Red Book" for the color of its cover, this 124-page resource can provide you with the complete administrative list of the national park system. Within it you'll be able to find administrative addresses, phone numbers, boundary information, and details on why the site is significant enough to be included within the national park system.
It will not, however, shed any light on campgrounds, lodgings or restaurants.
