19. Sequoia National Park – Tulare County, California
The giant sequoia trees are competing with the national redwood forests, located in the Sequoia National Park in California (via Buzzfeed). One of the oldest and largest trees globally is the General Sherman Tree, which stands about 275 feet tall, and is believed to be about 2,500 years old (via Buzzfeed). After perusing the giant forests, you can take a trip through the underground Crystal Cave. It has cooling streams and beautiful rock formations you’ll want to bring your camera for.
