Let us help. This short list of the country's must-sees includes parks that stand out for sheer beauty (Glacier National Park), enormity (the Grand Canyon), and novelty (Great Sand Dunes). It's no wonder we call the parks America's Best Idea. 01 of 33 Pacific Northwest Denali National Park, Alaska Daniel A. Leifheit/Getty Images In Alaska's most well-known national park, wildlife is diverse, mountains (including America's highest peak) are grandiose, and the subarctic landscape is astounding. It's no surprise that tourism to the park has increased drastically over the past few decades. The state of Alaska is home to some of America's most breathtaking scenery, full of glaciers, valleys, cliffs, lakes, and wildlife. And with over six million acres, Denali is no exception. 02 of 33 Pacific Northwest Glacier Bay National Park, Alaska Dave Bartuff/Getty Images Scientists have likened the icy Glacier Bay to a living laboratory due to the park's glacial retreat, plant succession, and animal behavior. As the melting ice retreats, new vegetation and mammals move in on land, while underneath the water's surface, humpback whales, killer whales and seals continue to call the region home. It's only accessible by boat or plane, but Glacier Bay is an area that deserves a visit, especially if you are a lover of nature and wildlife. 03 of 33 Pacific Northwest Olympic National Park, Washington PhotoAlto/Jerome Gorin/Getty Images The nearly one million acres of Olympic National Park offer visitors three distinct ecosystems ripe for exploration, including rainforest valleys, snow-capped peaks, and a colorful coast.
