Colorado has no scarcity of ski resorts, with Aspen only adding to the extensive list of excellent slopes the state can offer.

The town has access to four trail-covered mountains, as well as facilities for other winter outdoor activities such as snowshoeing, cross-country skiing, and hot air ballooning. The town also supports outdoor summer fun, with gorgeous natural landscapes and infrastructure for such pursuits as hiking, cycling, and fly fishing. Things to Do in Aspen

To reach the summit, visitors only need to climb another quarter mile by foot. On Mount Evans, there are several hiking and cycling trails beyond the car-friendly byway. The mountain has unique animal species living on its slopes, including mountain goats, marmots, and big horn sheep.

The country’s third most visited national park in 2015, Rocky Mountain National Park is a protected natural reservation spanning three ecosystems, montane (which is made up of grasslands, shrublands, and forests), subalpine, and alpine tundra.

Rocky Mountain National Park is located in northern Colorado and is a popular location for hiking, camping, and wildlife watching. Trail Ridge Road, which runs throughout the park, allows visitors to enjoy the beauty from the comfort of their cars as well.

Somewhat of a misnomer, Buffalo Overlook is a site within Colorado’s Genesee Park where lucky guests can catch a glimpse of bison roaming around a protected area. Although these bison are often referred to as buffalos, in fact, buffalos occur only in Asia and Africa, not in North America.

This location is where the first North American bison herds were reestablished in Colorado in 1914. Today, the bison can be seen from a vehicle, as a road equipped for automobile traffic leads up to the point. Although these giants may seem gentle from afar, they are actually quite temperamental and should be looked at, but not touched or heckled.

White River also has eight dedicated wilderness areas that show off the forest’s mountainous landscape. It has 1,900 miles of vehicle-friendly roadways and 2,500 miles of hiking trails, making it an excellent place to visit for trekking, wildlife watching, horseback riding, and camping.

Great Sand Dunes National Park is an unexpected gift from nature in southern Colorado. The park contains the country’s tallest sand dunes, representing a surprising focal point for the surrounding area, which consists of tundra, forest, and grasslands.

The dunes here are relatively new, having begun forming only 440,000 years ago. Activities here offer something different from the usual hiking and camping opportunities available in other national parks and forests. Guests to Great Sand Dunes can ride a sand sled down the 750-foot dune peaks, splash in the creek at their base, and even enjoy a clear night sky full of stars in this vast, treeless expanse.

Bent's Old Fort National Historic Site is a reconstructed historical site that gives Colorado visitors a chance to experience what life was like for fur trappers out West in the 1840s. The original fort was built of adobe in 1833 as a trading post for traders and the local Cheyenne and Arapaho Plains Indian tribes.

It was only open for 16 years, but it served as a key checkpoint along the Santa Fe trail for the military, travelers, and adventurers passing through the region. Today, the adobe building has been completely rebuilt, and trained historians offer guided tours of the settlement. Individuals can also hike along a 1.5-mile trail around the building or attend one of the site’s regularly scheduled special events.

Pikes Peak, the easternmost summit of the Rocky Mountains, is North America’s most visited mountaintop and the world’s second most popular destination peak after Japan’s Mount Fuji. Like many other Colorado sites, Pikes Peak gained notoriety during the Gold Rush of the mid-19th century. The mountain rises over 14,000 feet and is 8,000 feet taller than the nearest town of Colorado Springs.

There are three ways to reach the top. The first is by foot on the 13-mile-long Barr Trail. The second is by car along Pikes Peak Highway, and the third, and perhaps the most exciting, is via the Cog Railway. This 9-mile rail line takes several trains up the slope of the mountain to its summit each day, weather permitting.

The trail leading to Hanging Lake is one of Colorado’s most well-trodden, and for good reason. The lake shines with a beautiful, unusual turquoise color, which it gained and has maintained thanks to travertine depositions and the action of several unique geological processes.

An uphill trail, which is one mile long but nonetheless challenging because of the rocky terrain, leads up to the lake, which seems to “hang” among the Glenwood Canyon cliffs that encircle it. Swimming is not permitted in the lake, but several viewing platforms allow visitors to enjoy the one-of-a-kind green hues displayed by the lake and the verdant scenery around it.

Today, New Belgium is the fourth largest craft brewer and the eighth largest brewer overall in the United States. Tours to the brewery are available throughout the year. Visitors can learn about the brewing process and enjoy a tasting of the on-tap selection of the season.
