305 Best Sights in Colorado, USA

Outdoor cafés and tempting shops line this pedestrian-only 18-block, 1¼-mile thoroughfare, shaded by red-oak and locust trees. The mall's businesses run the entire socioeconomic range. There are popular meeting spots for business types at places like the Yard House in the Sheraton Hotel; a front-row view of the many street performers and goings-on from restaurants' sidewalk patios; and plenty of fast-food chains. Although some Denverites swear by the higher-end Cherry Creek Shopping District, the 16th Street Mall covers every retail area and is a more affordable, diverse experience. You can find Denver's best people-watching here. Catch one of the free shuttle buses at any corner that run the length of downtown. Pay attention when you're wandering across the street, as the walking area and bus lanes are the same color and are hard to distinguish.

The stonework of this 40-room cliff dwelling is impressive, but you're likely to be even more awed by the skill it must have taken to reach this place. Perched in a sandstone cove 600 feet above the floor of Soda Canyon, Balcony House seems suspended in space. Even with modern passageways and trails, today's visitors must climb a 32-foot ladder and crawl through a narrow tunnel. Look for the intact balcony for which the house is named. The dwelling is accessible only on a ranger-led tour.

This scenic, calorie-burning hike begins with a moderately level, half-mile journey to Nymph Lake. From here, the trail gets steeper, with a 425-foot elevation gain, as it winds around for 0.6 miles to Dream Lake. The last stretch is the most arduous part of the hike, an almost all-uphill 0.7-mile trek to lovely Emerald Lake, where you can perch on a boulder and enjoy the view. All told, the hike is 3.6 miles, with an elevation gain of 605 feet. Allow two hours or more. Moderate.

This lovely orchard 1 mile west of Paonia markets its own organic apples, apricots, cherries, peaches, pears, and plums throughout the summer. You can pick them yourself, along with a variety of other produce, or buy them in the shop in the form of homemade organic juices or hard cider; you'll also find local wines, art, honey, and more. The café serves tasty sandwiches, salads, and Colorado-style Mexican entrées that can be enjoyed indoors or out. There's live music outdoors on many summer evenings, and kids will keep themselves entertained on the variety of tree swings. Camping is also available.

Downtown Breckenridge's Historic District is one of Colorado's largest, with about 250 buildings on the National Register of Historic Places. The district is roughly a compact 12 square blocks, bounded by Main, High, and Washington Streets and Wellington Road. There are some 171 buildings with points of historical interest, from simple log cabins to Victorians with lacy gingerbread trim.

The grande dame of Denver hotels was built in 1892, and is still considered the city's most prestigious address. Famous guests have included President Dwight D. Eisenhower, Winston Churchill, and Beyoncé. Even if you aren't staying here, the Brown Palace lobby is a great place to sit on comfortable old couches, drink tea, and listen to piano standards (or harp, during afternoon tea). Reputedly this was the first atrium hotel in the United States; its ornate lobby and nine stories are crowned by a Tiffany stained-glass window.

The drive up Lookout Mountain to the Buffalo Bill Museum and Grave provides a sensational panoramic view of Denver that alone is worth the price of admission. It was this view that encouraged Bill Cody—Pony Express rider, cavalry scout, and tireless promoter of the West—to request Lookout Mountain as his burial site. Adjacent to the grave is a small museum with art and artifacts detailing Cody's life and times, as well as a souvenir shop. The grave is 100 yards past the gift shop on a paved walkway.

Established as an official National Monument in 2022, this historic site pays tribute to the 10th Mountain Division, a unique Army infantry unit from World War II that trained skiers to be soldiers. Trained for mountain conditions here, the soldiers eventually fought in Italy and Austria, facing some of the toughest terrain in the war. A self-guided tour offers 10 points of interest across the sprawling valley. The 53,804-acre site includes campgrounds and access to the Continental Divide Trail, which stretches 3,000-plus miles along the Rockies.

Spread across 176,000 acres of arid mesa and canyon country, the Canyons of the Ancients National Monument holds more than 20,000 archaeological sites, the greatest concentration anywhere in the United States. Some sites, like apartment-style cliff dwellings and hewn-rock towers, are impossible to miss. Others are as subtle as the remains of agricultural fields, springs, and water systems. They are powerful evidence of the complex civilization of the Ancestral Pueblo people. Lowry Pueblo, in the northern part of the monument, is a 40-room pueblo with eight kivas (round chambers used for sacred rituals). Its Great Kiva is one of the largest known in the Southwest.

Exploring the monument area can be a challenge: roads are few, hiking trails are sparse, and visitor services are all but nonexistent. The visitor center, which is also a museum, is 3 miles west of Dolores on Route 184. The best bet is a guided hike with the nonprofit Southwest Colorado Canyons Alliance ( www.swcocanyons.org/tours).

Discovered by two boys in 1880, the cave has been exploited as a tourist sensation ever since. The only way to enter the site is by purchasing a tour, but once inside the cave you'll forget the hype and commercialism of the gimmicky entrance. The cave contains examples of every major sort of limestone formation, from icicle-shaped stalactites and stump-like stalagmites to delicate anthodite crystals (or cave flowers), flowstone (or frozen waterfalls), and cave popcorn. Enthusiastic guides host easy 45-minute walking tours, adventurous cave expeditions, and lantern tours that last 1½ hours. An outdoor ropes course and rides like the Terror-dactyl, which swings riders off a 200-foot cliff, offer more fun outside of the cave.

For some of Boulder's prettiest views, follow Baseline Road west from Broadway to Chautauqua Park, nestled at the base of the Flatirons. Grab a picnic or ice cream cone at the General Store and relax on the lawn, or use the park as a launching point to 40 miles of hiking trails. Historic Chautauqua is also home to a tasty restaurant, the historic Chautauqua Dining Hall, open year-round for brunch and dinner. Or attend a lecture, silent film, or concert at the auditorium, which hosts the Colorado Music Festival and internationally renowned concerts every year. For a bird's-eye view of Boulder, keep going west on Baseline (which turns into Flagstaff Road) 1 mile to Panorama Point, and then 3½ miles to Realization Point.

This is one of the finest museums of its kind in North America, with constantly changing hands-on exhibits that engage children up to about age 10 in discovery. A three-and-a-half-story climbing structure soars through the center of the museum, complete with a bridge and gondola, along with a water area featuring geysers, pumps, and a 30-gallon structure that replicates a toilet flushing. Also among the 16 indoor playscapes and an outdoor area are a teaching kitchen where kids can cook real food; an art studio staffed by artists in residence; a grocery store; a veterinary office; and Fire Station No. 1, a real fire hall with a pole and kitchen. One of the biggest attractions is the Center for the Young Child, a 3,700-square-foot playscape aimed at newborns and toddlers and their caregivers; or little ones can enter Bubbles Playscape, where science and soap collide in kid-made bubbles up to 6 feet long.

This was the first major Mesa Verde dwelling seen by cowboys Charlie Mason and Richard Wetherill in 1888. It is also the largest, containing about 150 rooms and 23 kivas on three levels. Getting there involves a steep downhill hike and three ladders.

You may enter Balcony House or Cliff Palace by ranger-guided tour only so purchase tickets in advance.

The 90-minute, small-group "twilight tours" at sunset present this archaeological treasure with dramatic sunset lighting. Tour tickets are only available in advance at the Visitor and Research Center, Morefield Ranger Station, Durango Welcome Center, and online at  www.recreation.gov.

Taking its own name from the many peaks named after famous universities, the 168,000-acre Collegiate Peaks Wilderness Area includes eight mountains that tower more than 14,000 feet high. Forty miles of the Continental Divide snake through the area as well. The most compelling reason to visit Buena Vista is for the almost unequaled variety of hikes, climbs, biking trails, and fishing streams here. (Keep an eye out for hot springs, too.) Two ranger offices, one in Leadville and one in Salida, handle inquiries about this region.

Sheer red rock cliffs open to 23 miles of steep canyons and thin monoliths that sprout as high as 450 feet from the floor of Colorado National Monument. This vast tract of rugged, ragged terrain was declared a national monument in 1911 at the urging of an eccentric visionary named John Otto. Now it's popular for rock climbing, horseback riding, cross-country skiing, biking, and camping. Cold Shivers Point is just one of the many dramatic overlooks along Rim Rock Drive, a 23-mile scenic route with breathtaking views. The town of Fruita, at the base of Colorado National Monument, is a haven for mountain bikers and hikers. It makes a great center for exploring the area's canyons—whether from the seat of a bike or the middle of a raft, heading for a leisurely float trip.

Thousands of beer lovers make the pilgrimage to the venerable Coors Brewery each year. Founded in 1873 by Adolph Coors, a 21-year-old German stowaway, today it's the largest single-site brewery in the world and part of Molson Coors. Only guided tours with reservations are available; the tour explains the malting, brewing, and packaging processes. Informal tastings are held at the end of each tour and are included in the price of admission; for half the price of a tour, you can just sample beers. Reservations are required for tours and sampling, and you can buy souvenirs in the gift shop. A free shuttle runs from the parking lot to the brewery.

Straddling the Colorado–Utah border, Dinosaur National Monument is a must for any dinosaur enthusiast. A two-story hill teeming with fossils—many still in the complete skeletal shapes of the dinosaurs—greets visitors at one of the few places in the world where you can touch a dinosaur bone still embedded in the earth. The Colorado side of the park offers some of the best hiking in the West, along the Harpers Corner and Echo Park Drive routes and the ominous-sounding Canyon of Lodore (where the Green River rapids buffet rafts). The drive is accessible only in summer—even then, four-wheel drive is preferable—and some of the most breathtaking overlooks are well off the beaten path.

The late-19th- and early-20th-century commercial structures of the Downtown Boulder Historic District once housed mercantile stores and saloons, but today the stores here cater to modern tastes, with fair-trade coffees and Tibetan prayer flags. The period architecture—including Queen Anne, Italianate, and Romanesque styles in stone or brick—has been preserved.

The most entertaining way to relive the Old West is to take a ride on the Durango & Silverton Narrow Gauge Railroad, a nine-hour round-trip journey along the 45-mile railway to Silverton. Travel in comfort in restored coaches or in the open-air cars called gondolas as you listen to the train's shrill whistle. A shorter excursion to Cascade Canyon in heated coaches is available in winter. The train departs from the Durango Depot, constructed in 1882 and beautifully restored. Next door is the Durango & Silverton Narrow Gauge Railroad Museum, which is free and well worth your time.

This dome on the University of Colorado campus puts on planetarium shows and star talks, as well as laser shows choreographed to music by the likes of Pink Floyd, Bob Marley, and Queen. Showtimes vary somewhat, but generally laser shows take place on Thursday, Friday, and Saturday night, and star shows are sprinkled throughout the week, including some family matinees. The planetarium hosts live talks on Thursday evening. The Sommers–Bausch Observatory is open for free public viewing every Friday, weather permitting, when CU classes are in session.

This interesting landmark is located about 42 miles from Cortez, 65 miles southeast of Bluff, and 6 miles north of Teec Nos Pos, Arizona. The Four Corners Monument Navajo Tribal Park is owned and operated by the Navajo Nation. On the Colorado side is the Ute Mountain Ute of the Corners. Primarily a photo op, you'll also find Navajo and Ute artisans selling authentic jewelry and crafts, as well as traditional foods. It's the only place in the United States where you can be in six places at one time: four states and two tribal parks meet at one single point. Bring plenty of water.

These magnificent, eroded red-sandstone formations—from gnarled jutting spires to sensuously abstract monoliths—were sculpted more than 300 million years ago. Follow the road as it loops past such oddities as the Three Graces, the Siamese Twins, and the Kissing Camels or get an up-close look at the rocks with a guided climbing expedition booked at the visitor center. High Point, near the south entrance, provides camera hounds with the ultimate photo op: a formation known as Balanced Rock and jagged formations that frame Pikes Peak. The visitor center has maps of the trails and several geological, historical, and interactive hands-on displays, as well as a café. It's a short, paved hike into the park from the parking lot.

This 1920s narrow-gauge train connects Georgetown with the equally historic community of Silver Plume. The 6-mile round-trip excursion takes about 70 minutes, and winds through vast stands of pine and fir before crossing the 95-foot-high Devil's Gate Bridge, where the track actually loops back over itself as it gains elevation. You can add on a tour of the Lebanon Silver Mill and Mine, which is a separate stop between the two towns, as well as meals in the dining car. In fall and around the holidays, special trains run, including popular rides with Santa.

The 2.8-mile hike to Mills Lake can be crowded, but the reward is one of the park's prettiest lakes, set against the breathtaking backdrop of Longs Peak, Pagoda Mountain, and the Keyboard of the Winds. There's a modest elevation gain of 750 feet. On the way, about 1 mile in, you pass Alberta Falls, a popular destination in and of itself. The hike travels along Glacier Creek, under the shade of a subalpine forest. Give yourself at least four hours for hiking and lingering. Easy.

Newer and more relaxing than its famed sibling across town, Iron Mountain Hot Springs is geared to adults looking for a peaceful retreat. Seventeen mineral pools with views of the Colorado River and Mt. Sopris are scattered across the hilltop; temperatures vary from 98°F to 108°F. A large family pool, heated to 94°F, encourages young children to stay out of the soaking spas, and soothing music drowns out much of the noise from the nearby kids' area. On-site bars offer a variety of beer and wine for sipping at the pools, and the contemporary locker rooms maintain the property's spa–like atmosphere. In summer 2023, a new adults–only area complete with two large pools with waterfalls and eight riverside pools lined with relaxation pebbles opened to visitors over 21. Reservations are required and visits are limited to three hours.

With Navajo silver and Hopi pottery, the Koshare Indian Museum contains extensive holdings of Native American artifacts and crafts. It also displays pieces from Anglo artists, such as Remington, known for their depictions of Native Americans. The Koshare Indian Dancers—actually local youth—perform regularly.

Resting in the heart of Summit County at 9,017 feet is the Front Range's answer to a day at the beach—beautiful Lake Dillon and her two ports, Dillon, just off I–70 on the south, and Frisco, off I–70 and Route 9 on the west. The lake is actually backed up by a 231-foot earth-filled dam that fills the valley where Dillon once sat. During the frequent Western droughts, when water levels can drop dramatically, collectors wander along the exposed shores hunting for artifacts from this Rocky Mountain Atlantis. Below the mile-long dam the Blue River babbles past the outlet shopping haven and turns into miles of gold-medal fly-fishing waters on its journey north. There are more than 27 miles of gravel beaches, marshes, peninsulas, and wooded islets for picnickers to enjoy, many accessible from a 7½-mile paved trail along the northern shores, or from the informal dirt paths elsewhere. Gaze out at the deep blue waters from Sapphire Point Lookout (a short ½-mile hike on the south side of the lake) any nice day, and you'll see a flotilla of motorboats, sailboats, canoes, kayaks, and sailboarders dancing in the waves. In winter the frozen waters are enjoyed by ice anglers and cross-country skiers. Because the lake is a drinking-water source, swimming is not permitted, and the lake is patrolled vigorously by Summit County sheriffs.

One of just three ranges in the United States set aside for wild horses, this range encompasses 36,113 acres of rugged canyons and plateaus in the Bookcliffs. Between 90 and 150 wild horses roam the sagebrush-covered hills. Most years new foals can be spotted with their mothers in spring and early summer on the hillsides just off the main trails. Local favorites for mountain biking and hiking include the Coal Canyon Trail and Main Canyon Trail, where the herd often goes in winter. Vehicles are permitted on designated trails.

The majestic Maroon Bells, twin peaks more than 14,000 feet high, are so colorful, thanks to mineral streaking, that you'd swear they were blanketed with primrose and Indian paintbrush. It's one of the most photographed spots in the country, which is why reservations are required to ensure the view. Before 8 am and after 5 pm in the summer, cars can drive all the way up to Maroon Lake (though vehicles with children in car seats or people with disabilities are allowed to do so at any time). Otherwise, parking is available at the Aspen Highlands garage, where guided bus tours and shuttles leave regularly in summer months.

Ten miles west of Grand Junction, stretching from Fruita to just across the Utah border, the McInnis Canyons National Conservation Area (formerly Colorado Canyons National Conservation Area) is rife with natural arches, along with numerous rock canyons, caves, coves, and spires. Rattlesnake Canyon has nine arches, making it the second-largest concentration of natural arches in the country. The canyon can be reached in summer from the upper end of Rim Rock Drive with four-wheel-drive vehicles or via a 7-mile hike by the intrepid.

Though much of the territory complements the red-dirt canyons of Colorado National Monument, McInnis Canyons is more accessible to horseback riding, mountain biking, all-terrain vehicle and motorcycle trails, and for trips with dogs (most of these activities aren't allowed at the monument). Designated in 2000 by Congress, the conservation area was created from a desire of nearby communities to preserve the area's unique scenery while allowing multiple-use recreation. Be prepared for biting gnats from late May to late July. Contact the Bureau of Land Management for a map before venturing out.
