There are still a few days left to celebrate National Park Week, which runs from April 18-26.
Although it's too late to take advantage of a weekend of free admission to the country's national parks (that was last weekend)—there are still ways to celebrate America's Best Idea from the soft glow of your computer screen. Maybe that's all it will take to inspire a trip to a national park near or far.
The Los Angeles Times has put together a slideshow of great images from the 20 most-visited national parks, including some incredible photos from some of my personal favorites: Zion Canyon National Park in Utah (#8), Yellowstone National Park (#4), and Grand Canyon National Park (#2). Unfortunately, the photo for Glacier National Park (#10) is actually an image from Peyto Lake in Banff National Park in Canada. Thanks to Twitter user @joelpavila for pointing out that error.
Yahoo Travel also shares a series of the best selfies at national parks taken by both the Yahoo Travel Explorers and the Yahoo Travel staff. To accompany her selfie taken at the iconic tunnel view vantage point of Yosemite Valley, writer Lana Lee Neil offers the words Ansel Adams used to describe that park, but which could apply to many of the places in the national park system: "Yosemite Valley, to me, is always a sunrise, a glitter of green and golden wonder in a vast edifice of stone and space."
