Colorado has no scarcity of ski resorts, with Aspen only adding to the extensive list of excellent slopes the state can offer. Situated among the Elk Mountains in White River National Forest, Aspen was established as a mine town during the silver mining boom of the 19th century, but today its identity is almost inextricably connected to skiing. 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.

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.

Rocky Mountain National Park (1 hour 40 min)

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. The park owes its ecological diversity to its unique topography, which includes the impressive Rocky Mountains, a series of lakes, and even some small glaciers. 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.

Buffalo Overlook (30 min)

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.

Bent's Old Fort National Historic Site (3 hours)

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.

Hanging Lake Trail (2 hours 30 min)

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.
