Yellowstone National Park is first in many ways. It is the first national park in the world. It is the largest park in the lower 48 states, larger than the states of Delaware and Rhode Island combined. It has some of the most famous park features, such as Old Faithful, the Grand Canyon of the Yellowstone, and freely roaming herds of buffalo. It also includes the nation's largest wildlife preserve, an enormous lake, the Continental Divide, some 10,000 hydrothermal features, and over 1,000 miles of trails. And its diversity of attractions is a match for any location on the planet. Old Faithful Geyser, Upper & Lower Falls, Old Faithful lodge, Yellowstone Lake, Mammoth Hot Springs, Grand Canyon of Yellowstone, Norris Geyser Basin and of course wild animals are just some of the sights to see while visiting the park.

Glacier National Park is named for the rivers of ice that continue to carve its spectacular alpine landscape. Glacier continually ranks as the most pristine of America's national parks and the one people would most like to revisit. It is set in a rugged section of the northern Rockies and joins Waterton Lakes National Park in Alberta, Canada. Together they create Waterton-Glacier International Peace Park World Heritage Site. In 1910 the Park was established, becoming the country's 10th National Park. The Going-to-the-Sun Road, completed in 1932 after 11 years of work, is the marquee drive in Glacier and perhaps the most scenic stretch of tarmac in all of North America. It has been described as a "don't look down" road. It bisects the northern and southern halves of the park, crosses the Continental Divide, and is designated a National Historic Landmark.
