These natural spaces are out of this world!
Dry Tortugas National Park — which sits off Key West, Florida — isn't your typical national park. During the Civil War, this 101 square miles archipelago served as a prison. There you can find the 19th-century Fort Jefferson, which you'll discover is surrounded by coral reefs, seven tiny islands, and lots of marine life.
Petrified Forest National Park feels like a magical fairyland in Arizona. It's most famous for its unique wood stones — they’re actually fossilized chunks of timber filled with bright and colorful quartz, stretching across 85,542 square miles of southwest desert.
