Since 1872 when Yellowstone National Park became the country’s first national park, Americans and international visitors have been enjoying these federally protected lands. From Acadia in Maine to Biscayne in Florida to Denali in Alaska, the National Parks system includes 59 parks in 29 states, plus American Samoa and the U.S. Virgin Islands. The National Geographic Store's National Parks Gear shop lets you show your love for a favorite park with T-shirts, water bottles, and notebooks from CafePress.com. Or shop a selection of wool blankets by Pendleton from their National Parks series. Read more about Pendleton Wool Blankets on the National Geographic Store blog.
