US National Parks will have free entrance for the long week of Saturday April 21 to Sunday April 29, 2012.
Find a nearby national park here. Then, start making some plans to visit!
When we think of national parks, we think of the big ones like Yosemite, Everglades, or Canyonlands. However, there are so many less well-known national parks, some of which may be closer to where you live.
April 21 through 29 is the only free national park week in 2012, though there will be some upcoming free days (in June, September, and November.)
