Situated in Southern Colorado, the Great Sand Dunes National Park is an impressive sight. Shaped by winds blowing from and against the nearby Sangre de Cristo Mountains, the piles of sand climb to more than 750 feet (230 meters), making them the tallest dunes in North America. Sand-boarding, skiing and sledding on the dunes are the park’s most popular activities, and there are medium-size slopes to slide on located near the main parking area. A longer hike to the north brings thrill seekers to a 300-foot (90 meter) slope that tumbles onto into Medano Creek.
At 265,000 acres, Rocky Mountain National Park isn't the country's largest national park, nor is it the most-frequented with about 4 million annual visitors (compared to Great Smoky Mountains National Park's more than 11 million visitors). But there is something definitively magical about RMNP, which rises 12,183 feet into the Colorado sky. The main attraction is hiking its 350-some miles of trails that wind through pine and spruce forests, glittering alpine lakes, swaths of wildflowers and if you're lucky, some elk or bighorn sheep. And maybe it's the thinner atmosphere that goes to visitors' heads, but even the most jaded report feelings of awe and wonder after a day or two of breathing in that refreshing mountain air.

Rocky Mountain National Park covers 410 square miles and includes Longs Peak (14,255 feet high), 18 named peaks above 13,000 feet, 150 named lakes, and the highest continuously paved highway in the U.S. — Trail Ridge Road.

While January isn’t typically busy, Murdock said that in December 2017, the park had 112,000 visitors. Visitors have shown up every day since the shutdown began, even though recent snowstorms and unplowed roads have made the park essentially off limits to vehicles.  Anyone can still walk in, though, and Murdock has seen proof that that’s happening.
