The best way to celebrate the 100th anniversary of the National Parks system is, of course, to support and visit them, including Colorado gems such as Rocky Mountain National Park and Great Sand Dunes National Park and Preserve. But short of that, you can remind yourself of their grandeur and history in the most virtually immersive way possible by checking out “National Parks Adventure,” a new 3-D IMAX documentary premiering at the Denver Museum of Nature & Science on May 27.
