305 Best Sights in Colorado, USA

This regional museum has a fine permanent collection of modern art and excellent rotating exhibits. Some highlight the cultural contributions of regional artists; others focus on famous artists such as the glassmaker Dale Chihuly and American pop artist Andy Warhol. Enjoy the view of Pikes Peak and the mountains from the patio in the summer.

This 3,100-mile corridor, which extends from Montana's Canadian border to the southern edge of New Mexico, enters Rocky Mountain National Park in two places, at trailheads only about 4 miles apart and located on either side of the Kawuneeche Visitor Center on Trail Ridge Road, at the park's southwestern end. Within the park, it covers about 30 miles of spectacular montane and subalpine terrain and follows the existing Green Mountain, Tonahutu Creek, North Inlet, and East Shore Trails. Moderate.

The 0.3-mile hike to these Wild Basin Area falls is a good option for families, as the terrain is relatively flat (there's only a 15-foot elevation gain). Easy.

Downtown Trinidad, called the Corazón de Trinidad, is a National Historic District, mixing historic original brick-paved streets and architecture with modern concerts, restaurants, shops, and festivals. Residents and officials recently launched a bit of a revival here with big plans for the creative district.

The cultural center has exhibits on regional artists and Ancestral Pueblo culture, as well as events and fairs. Summer evening programs may include Native American dances and storytelling.

When gold was discovered here in 1887, the Country Boy Mine became one of the region's top producers---lead and zinc, which were vital for U.S. efforts in World War I and World War II, were big here, too. The gold mine tour takes visitors more than 1,000 feet deep into the mountain. Visitors can pet the donkeys that roam the area, pan for keepable gold, or go on a treasure hunt with a metal detector. The mine has a 55-foot ore-chute slide, historic buildings, and plenty of mining artifacts.

Occupying the original Denver & Rio Grande Railroad Depot, the museum paints a vivid portrait of the town's rough-and-tumble early days. It also includes World War I and World War II exhibits.

This museum is housed in rooms that modern miners blasted out of solid rock to commemorate the lives of 1880s-era miners and trace the history of mining in the area. In summer, there are guided tours at 10 and 3 daily, but before 2:15 pm you can also take a self-guided audio tour. Reservations are recommended.

Housed in an 1893 hardware store, this museum showcases the essentials for life in an 1880s mining town, such as clothing, furniture, and household items. There's an intricate diorama of the town in the 1920s, complete with a moving train, plus exhibits on skiing, sledding, biking, and Flauschink, a quirky local ceremony that welcomes the return of spring.

The museum set in five historic buildings—including a vintage railway depot—contains a vast collection of artifacts, photos, and exhibits that provide a glimpse into mining life at the turn of the 20th century.

Seven galleries of campus history sweep you into exploring the past, present, and future of university achievements and traditions. Warp into space with the University of Colorado's astronauts, and see an Apollo 15 moon rock; strut to the tunes of master swing conductor Glenn Miller; challenge yourself to building a 1.5-million-LEGO-brick model of the Boulder campus; and see if you can name the school's latest Olympians.

This 4.6-mile, three-hour (round-trip) hike takes you through meadows and stands of aspen trees and up 540 feet in elevation to a lake with water lilies. Moderate.

Take a day trip on the Cumbres & Toltec Scenic Railroad, an 1880s steam locomotive that chugs through portions of Colorado's and northern New Mexico's rugged mountains that you can't reach via roads. It's the country's longest and highest steam-operated railroad. The company offers round-trip train routes, several bus-and-train combinations, one-way trips, and themed rides.

This recreation area, part of the National Park Service, encompasses three reservoirs along 40 miles of the Gunnison River and can be accessed at the bottom of the East Portal Road. Blue Mesa, nearly 20 miles long, is the largest body of water in Colorado; Morrow Point and Crystal are fjordlike reservoirs set in the upper Black Canyon of the Gunnison. All three reservoirs provide water-based recreational opportunities, including fishing, boating, and paddling, but only Blue Mesa offers boat ramps. Excellent fly-fishing can be found upstream (east) of Blue Mesa Reservoir along the Gunnison River. A variety of camping and hiking opportunities are also available. The Elk Creek Visitor Center on U.S. 50 is available year-round for trip-planning assistance. Camping at the Lake Fork Campground in the park provides a perfect middle ground between the North and South Rims of Black Canyon, ideal for seeing both sides over a weekend.

Despite its name, the 6-mile Deadhorse Trail is actually a pleasant hike, starting on an old service road from the Kneeling Camel view on the North Rim Road. The trail's farthest point provides the park's easternmost viewpoint. From this overlook, the canyon is much more open, with pinnacles and spires rising along its sides. Moderate.

This 6-mile round-trip trek to the top of 10,083-foot Deer Mountain is a great way for hikers who don't mind a bit of a climb to enjoy the views from the summit of a more manageable peak. You'll gain more than 1,000 feet in elevation as you follow the switchbacking trail through ponderosa pine, aspen, and fir trees. The reward at the top is a panoramic view of the park's eastern mountains. Difficult.

Denver's first firehouse was built in 1909 and now serves as a museum where original items of the trade are on view, including uniforms, nets, fire carts and trucks, bells, and switchboards. Artifacts and photos document the progression of firefighting machinery from horses and carriages in the early 1900s to the flashy red-and-white trucks of today.

The state's most popular cultural attraction, this easily navigated property's best-known exhibit showcases man-eating Komodo dragons in a lush re-creation of a cavernous riverbank. Another popular exhibit is The Edge, a series of overhead yards and bridges that allow the Amur (Siberian) tigers to roam 12 feet above visitors. The 10-acre Toyota Elephant Passage houses elephants, gibbons, rhinos, clouded leopards, and tapirs, along with other animals from the Asian continent. The Conservation Carousel ($2) rotates in the center of the 80-acre zoo, with handcrafted endangered species as mounts. A 7-acre Primate Panorama houses 31 species of primates in state-of-the-art environments that simulate the animals' natural habitats, while the Pinnacol African Penguin Point habitat showcases the endangered African penguin. Other highlights include a nursery for baby animals; seal shows; the electric Safari Shuttle, which snakes through the property as you are treated to a lesson on the zoo's inhabitants; and the usual lions, tigers, bears, giraffes, and monkeys. The exhibits are spaced far apart along sprawling concrete paths, so build in plenty of time to visit.

Roaring robotic stegosaurs and meat-shredding animatronic allosaurs prowl Dinosaur Journey, a fun, informative attraction just off I–70 a few minutes from the western entrance to Colorado National Monument. Unlike many museums, this one encourages kids to touch everything—friendly paleontologists may even allow kids to hold a chunk of fossilized dino dung. In addition to the amazing lifelike replicas, there are more than 20 interactive displays. Children can stand in an earthquake simulator; dig up "fossils" in a mock quarry (the pit is made of crushed walnut shells); or make dino prints in dirt, along with reptile and bird tracks for comparison. The museum also sponsors daily digs nearby, where many of the fossils were found. Local volunteers are at work cleaning and preparing fossils for study.

The Dinosaur Quarry Exhibit Hall showcases an estimated 1,500 dinosaur bones that date to the late Jurassic Period still embedded in the clay. Open daily, the Exhibit Hall is ranger-guided only in the winter; check the website or call ahead for shuttle hours and access availability. Fossils are visible only from the Utah side of the monument, not the Colorado side. A half mile away is a massive 7,595-square-foot visitor center.

On the north side of the South Platte across from Elitch Gardens, this is the only million-gallon aquarium between Chicago and the West Coast. It has four sections that show aquatic life in all its forms, from the seas to the river's headwaters in the Colorado mountains. The 250-seat Aquarium Restaurant surrounds a 50,000-gallon tank filled with sharks and fish. Other highlights include an expanded stingray touch pool, a gold-panning area, animatronic creatures, and an interactive shipwreck. The aquarium also has a lounge with a weeknight happy hour, and the truly adventurous can learn how to scuba dive or snorkel in the tanks.

Come to this newly renovated, luxurious hot springs resort to soak your aching bones after a day of hiking or skiing. The complex includes an Olympic-size, saltwater swimming pool infused with aquagen, and 27 total natural mineral pools ranging from 98°F to 110°F; all are open year-round. The pools are outdoors, perched at the base of the mountain and thoughtfully designed to blend in with nature. The grounds also feature a spa, sauna, reflexology path, food carts and fire pit, stage for live music, stream, separate adults-only area, and hydrotherapy "yin-yang" pool.

An easy hike of 0.3 miles from East Inlet trailhead, just outside the park in Grand Lake, will get you to Adams Falls in about 15 minutes. The area around the falls is often packed with visitors, so if you have time, continue east to enjoy more solitude, see wildlife, and catch views of Mount Craig from near the East Meadow campground. Note, however, that the trail beyond the falls has an elevation gain of between 1,500 and 1,900 feet, making it a more challenging hike. Easy.

This picnic area, located at the bottom of the canyon at a bend in the river, accommodates large groups. There are tables, a large shaded shelter, and outhouses.

The only way to access the Gunnison River from the park by car is via this paved route, which drops approximately 2,000 feet down to the water in only 5 miles, giving it an extremely steep grade. Vehicles longer than 22 feet are not allowed on the road. If you're towing a trailer, you can unhitch it near the entrance to South Rim campground. The bottom of the road is actually in the adjacent Curecanti National Recreation Area. There you'll find a picnic area, a campground, a primitive riverside trail, and beautiful scenery. A tour of East Portal Road, with a brief stop at the bottom, takes about 45 minutes. Immediately after arrival through the park's South entrance, take a right on East Portal Road.

Dedicated to the 19th-century miner turned environmentalist who helped create Denver's Museum of Nature and Science, this museum hosts realistic stuffed animals and interactive exhibits like the hands-on taxidermy workbench.

A nicely designed repository for the city's history, El Pueblo History Museum extends its scope to chronicle life on the plains dating back before Colorado statehood. It tells of Pueblo's role as a cultural and geographic crossroads, beginning when it was a trading post in the 1840s. Hands-on features—a giant teepee where guests can go inside and play historic drum replicas; a dress-up chest full of pioneer clothing and hats; and a covered wagon that is just the right height for small hands to discover the trinkets on board—make this museum fun for the whole family. Remnants of the original trading post are now an archaeological dig enclosed in a pavilion next to the museum.

With steep canyon walls, a rushing creek, verdant pine forests, 10 picnic sites with multiple tables, and 12 miles of trails, this park attracts thrill-seekers and nature lovers alike. Rock climbers scale the sandstone walls, kayakers charge the rapids of South Boulder Creek (if stream flow allows), and anglers cast lines for brown and rainbow trout. The Streamside Trail parallels South Boulder Creek for ½ mile (wheelchair accessible for 300 feet). The 1-mile (one-way) Fowler Trail is wheelchair accessible, with interpretive signs and great views for climbers. For Continental Divide views, take the 3½-mile (round-trip) Rattlesnake Gulch Trail, which climbs 800 feet. Snowshoeing is popular here in winter. Mountain bikers crank on Rattlesnake Gulch Trail and the Walker Ranch Loop (accessed from the Crescent Meadows trailhead off Gross Dam Road). Hikers can climb the 3½-mile (one-way) Eldorado Canyon Trail to Crescent Meadows. The park is frequently at capacity on weekends and holidays, so weekday and evening visits are recommended.

This elaborate and thrilling park was a Denver family tradition long before its 1995 relocation from northwest Denver to its current home on the outskirts of downtown. The park's highlights include hair-raising roller coasters and thrill rides; for younger kids and squeamish parents there are also plenty of gentler attractions such as bumper cars and tea cups. Twister II, an update of the classic, wooden Mister Twister, is from the original Elitch Gardens, as is a 100-foot-high Ferris wheel that provides sensational views of downtown. A 10-acre water-adventure park is included in the standard entry fee. You can spend a whole day at either the water park or the main park. Over Halloween, Thanksgiving, and Christmas, the park is open for holiday-themed events.
