The National Park Service is celebrating their 100th birthday with free entry to all 413 national parks this weekend.

Talk about perfect timing. School has started, but it isn't crazy busy yet with homework and school sports, so you can still enjoy a weekend away at a national park.

The free national park entry goes August 25th through the 28th and includes Craters Of The Moon, City of Rocks, Yellowstone, Zions, and all 413 other national parks.
