The park may be accessed through Estes Park or via the western entrance at Grand Lake. Trail Ridge Road, also known as U.S. Route 34, connects the eastern and western sides of the park.[91] The park has a total of five visitor centers. The Alpine Visitor Center is located in the tundra environment along Trail Ridge Road, while Beaver Meadows and Fall River are both near Estes Park, with Kawuneeche in the Grand Lake area, and the Moraine Park Discovery Center near the Beaver Meadows entrance and visitor center.[9]
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. 
Enos Mills, the main figure behind the creation of Rocky Mountain National Park, enjoyed walking to Lily Lake from his nearby cabin. Wildflowers are common in the spring and early summer. In the winter, the trail around the lake is often suitable for walking in boots, or as a short snowshoe or ski. Other lakes in the Wild Basin include Chasm Lake, Snowbank Lake, Lion Lakes 1 and 2, Thunder Lake, Ouzel Lake, Finch Lake, Bluebird Lake, Pear Lake, and Sandbeach Lake. Many of the lakes have backcountry campsites. Waterfalls include Ouzel Falls, Trio Falls, Copeland Falls, and Calypso Cascades.[47]
Cushion plants have long taproots that extend deep into the rocky soil. Their diminutive size, like clumps of moss, limits the effect of harsh winds. Many flowering plants of the tundra have dense hairs on stems and leaves to provide wind protection or red-colored pigments capable of converting the sun's light rays into heat. Some plants take two or more years to form flower buds, which survive the winter below the surface and then open and produce fruit with seeds in the few weeks of summer. Grasses and sedges are common where tundra soil is well-developed.[73]
The ski resort town of Vail is one of the best places to visit in Colorado in winter but it's also a pleasant place to enjoy at any time of year. When it comes to skiing, this is one of the top ski resorts in Colorado, with seemingly endless runs for all levels of skiers. The town at the base of the ski hill is postcard cute, with chalet-style restaurants, shops, and hotels that make you feel like you are in the heart of the Alps. This is a high-end resort with luxury hotels, fine dining, and designer stores.
Straddling the Continental Divide, the Rocky Mountain National Park covers some of the most beautiful mountains in the world. There are 77 mountains in the park with elevations that range from 7,500 to over 12,000 feet (2,200 to 3,600 meters). Most of the more than 3 million people who visit the park each year spend at least one night in one of the park’s many drive-in campgrounds. More than 350 miles of hiking trails offer visitors the chance to view the park’s wildlife, which includes hundreds of elk, bighorn sheep and deer. There is also the specially built scenic Trail Ridge Road, the highest paved road in any of the National Park in the United States.
You can climb and slide on the dunes or test your boarding skills cruising down the sand. On hot days, children and even adults enjoy splashing around in the Medano Creek that runs along the base of the dunes. Hiking trails run through the forest on the edge of the dunes. The four-wheel drive Medano Pass Primitive Road opens up some unique terrain, and car camping sites are located along the roadside. Regular camping is available at the Pinon Flats campground, which offers both tent and RV campsites.
