America's National Parks are home to some of the world's most breathtakingly beautiful wilderness. Protected by the federal government, many acres of these parks remain wild, extremely remote and virtually untouched by humans. Sounds heavenly right? With over 400 National Park sites across America spanning more than 84 million acres, its easy to see how there could be room for something evil and undiscovered lurking deep within the forests. Mysterious disappearances, terrifying cryptid sightings and possible alien encounters are just the beginning. Because as beautiful as they are, National Parks are creepy AF!
