A colossal tribute to four of our greatest presidents, Mount Rushmore National Memorial in South Dakota captivates and overwhelms nearly 3 million visitors a year. Most popular during the summer, we think Presidents’ Day is a perfect time of year to feature this remarkable park. Say hi to Washington, Jefferson, Lincoln and Theodore Roosevelt when you go!

These two little red foxes snoozing at Maine’s Acadia National Park are beyond cute! A mother fox gives birth to a litter of 2-12 kits, which the parents raise together. When the kits are about seven months old, they’re ready to strike out on their own. Check out more photos of cuddly animals: http://on.doi.gov/affectionateanimals.

Zion National Park in Utah boasts some of the most scenic landscapes in the southwestern U.S. Within its 229 square miles are high plateaus, a maze of deep sandstone canyons and the gorgeous Virgin River. The soft scents of pine and juniper drift on the air. A winter sunset coloring the sky above this dramatic scene is an unforgettable experience. Photo by David Curry (http://ift.tt/18oFfjl).

Sequoia National Park is the land of giants with huge mountains, deep canyons and the world’s largest trees. It can be hard to appreciate the size of the giant sequoias – the largest are as tall as an average 26-story building, and their diameters at the base exceed the width of many city streets. Explore this special place and all other public lands with free entrance on Monday for Presidents’ Day. Photo by Volunteer-in-Parks Hal Gamble.
