Ever dream of walking across lava fields in Hawaii, spelunking through a Carlsbad cavern, or dropping into a crevasse in Alaska’s Kenai Fjords? As reported by TechCrunch, you can take a 360-degree virtual tour of several amazing national parks with Google’s Hidden Worlds of the National Parks online exhibit. While less immersive than the virtual tours, the site also provides Google Street Views of popular parks including Yellowstone and Yosemite. Active Junky highly recommends experiencing National Parks in person, but this is a fun alternative that helps in planning a big trip. Have a look for yourself.
