Kenai Fjords National Park in Alaska
Though Denali is the more famous park in Alaska, Kenai Fjords in south-central Alaska, near the town of Seward, can be just as impressive. The site of one of the four major ice caps in the U.S., the land of glacier lakes and valleys is home to tens of thousands of breeding birds, in addition to sea lions, sea otters, and seals.
Rocky Mountain National Park in Colorado
The grandeur of the Rocky Mountains, with peaks towering over 14,000 feet, is accessible by Trail Ridge Road, which crosses the Continental Divide. Go in fall, when the elk are out in big numbers for the annual mating season.
