Did you know how beautiful national parks are in winter?

While many national parks are at their busiest in the summer months, they're arguably at their most beautiful (and serene) in the heart of winter. Not convinced? Feast your eyes on these winter photographs from the @USInterior Instagram page.

#MountRainier stands as a icon in the #Washington landscape. Scott Kranz (@scott_kranz) captured this striking pic of the mountain in January while backcountry skiing the nearby #TatooshRange in Mount Rainier #NationalPark.

Northern lights at White Mountains National Recreation Area

Picture yourself under the #NorthernLights at White Mountains National Recreation Area in #Alaska. Bob Wick – who caught this dramatic green display – describes his first experience photographing the #auroraborealis: "It was interesting to see how dynamic and fickle the display was, going from a dim glow to bright, dancing molten light pouring from the skies in a matter of 30 seconds. I have never seen or photographed anything in the #nightsky that compares!" Photo by Bob Wick, @mypubliclands

Frosty hoodoos in Bryce Canyon National Park

#BryceCanyon National Park (@brycecanyonnps) in #Utah shimmers in sunlight and snow. We love how the snow clings to the trees and hoodoos (odd-shaped pillars of rock left standing from the forces of erosion). What a terrific #winter scene. Photo by Curtis Kautzer (www.sharetheexperience.org).
