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.

Bon Secour National Wildlife Refuge encompasses some of Alabama’s last remaining undisturbed coastal barrier habitat. The name Bon Secour is French for “safe harbor,” very appropriate considering the sanctuary it provides for native flora and fauna. This refuge is a natural oasis of wildlands, where wildlife can exist without harm. It may be too cold to go in the water, but even in winter, a walk on the beach can be a beautiful experience.

The stillness of a winter sunrise is a moment to cherish at Rachel Carson National Wildlife Refuge in Maine. Established in 1966, the refuge protects salt marshes and estuaries important for migrating birds. Stretching from the coast to inland forests, the refuge offers amazing views and wildlife watching on five excellent trails. Photo by Ward Feurt, U.S. Fish and Wildlife Service.
