San juan Mountains
One of the most photogenic locations in the Colorado Rockies has to be the San Juan Mountains. These peaks, located in the southwestern corner of the state near the borders of New Mexico and Utah, are a landscape photographer’s favorite. In late September, the aspen trees that dominate the terrain turn yellow, creating vast carpets of color between the mountains. The best hiking can be found on the many trails around the Mount Sneffels Wilderness, where hikers can explore vast stretches of alpine tundra beauty and colorful lakes.
Elk mountains & Sawatch range
North of the San Juans are the equally stunning Elk Mountains and the surrounding Grand Mesa, Uncompahgre, and Gunnison National Forests. This area is home to some of Colorado’s most scenic mountain towns, including Aspen and Crested Butte. While here, photographers should be sure to make the obligatory stop at the famous Maroon Bells and explore the numerous peaks between Highways 133 and 82. Similar to the San Juans, the terrain is packed with aspen trees, making it particularly beautiful in the fall.
Black Canyon of the Gunnison River National Park
Black Canyon of the Gunnison National Park is a major landmark in western Colorado, located between the San Juan and Elk Mountains. At 48 miles long and thousands of feet deep, the canyon is truly a dramatic sight. The national park encompasses the most impressive section of the canyon and showcases its massive walls. Because of the narrowness of its walls, the canyon receives only 33 minutes of light a day, giving it its "Black Canyon" moniker.

Sawtooth mountains
Idaho is well-known for its rugged backcountry wilderness and mountain beauty. The Rockies stretch through much of the state, including the central portion and the northern panhandle. Perhaps the most notable section, however, is the Sawtooth Mountains in central Idaho. More than 40 trails totaling hundreds of miles traverse these jagged peaks and offer prime alpine hiking and camping experiences.
One of the most scenic and popular backpacking hikes in the region is a nearly 30-mile loop trek that starts south of Stanley, Idaho, and crosses a number of scenic backcountry lakes, including Petit Lake, Alice Lake, Toxaway Lake, and Imogene Lake. This epic trek, through the heart of the Sawtooths, is an absolute classic in the American Rockies.

Yellowstone national park
Though not known for its mountains, Yellowstone National Park is located squarely in the North American Rocky Mountain corridor and contains one of the largest collections of geothermal features (hot springs, fumaroles, geysers, and mud pots) in the world. These estimated 10,000 features are powered by their position over the Yellowstone hotspot, which lies beneath the massive Yellowstone caldera—a supervolcano that, if it erupted, would be one of the largest in the world. The park is a wonderland of colors, shapes, and smells, not to mention the huge collection of animals that call this park home.
The park is divided into a series of smaller geothermal zones, including Midway Geyser Basin, Upper Geyser Basin, Mammoth Hot Springs, West Thumb Geyser Basin, and Norris Geyser Basin. However, the two formations that attract the most attention are Old Faithful, a cone geyser that consistently erupts every 44 minutes to 2 hours, and Grand Prismatic Spring, an incredibly colorful hot spring that is one of the largest in the world.
Grand Teton National Park
No visit to Wyoming would be complete without driving Highway 89/191 and its amazing westward view of the Grand Tetons. This road, along with Teton Park Road, offers vistas of these awesome vertical peaks that rise from the flat prairie at their base. The national park offers a number of hiking trails around the peaks, but grand views are accessible right off the road. One of my favorites is Oxbow Bend, a stunning perspective of the Snake River in front of Mount Moran.
