Best places to hike in Colorado range from short paved trails at the base of red rock towers to steep climbs that reach the top of 14,000 foot peaks. Colorado draws millions of hikers every year because it offers something for everyone. You can walk a flat mile with your kids in the morning and stand on a mountain summit the next day. This guide covers the state’s most rewarding trails, organized by region, so you can plan a trip that matches your fitness level, your schedule, and the kind of scenery you want to see.
Whether you are visiting for a weekend or planning a longer Colorado road trip, this list will help you choose trails that are worth the drive. Each section includes real trail names, distances, and difficulty levels so you can plan with confidence.
Why Colorado Is a Hiker’s Dream Destination
Colorado has more than fifty peaks over 14,000 feet, four national parks, and thousands of miles of maintained trails. The state’s dry climate means most trails are hikeable from late spring through fall, and many lower elevation trails stay open all year. The scenery changes dramatically depending on where you go. In the north you will find glacier carved valleys and alpine lakes. In the south you will find towering sand dunes set against snowcapped mountains. In the central mountains you will find some of the tallest peaks in the country.
Before you pick a trail, think about three things: your fitness level, how well your body has adjusted to elevation, and how much time you have. Colorado’s high altitude affects everyone differently, even experienced hikers from sea level areas, so it pays to start with an easier trail and work your way up.
1. Rocky Mountain National Park
Rocky Mountain National Park sits about ninety minutes from Denver and holds more than 350 miles of trails. It is home to over one hundred peaks above 11,000 feet, including Longs Peak, and it offers some of the best alpine scenery in the entire country. The park now requires timed entry permits during the busy season, from late May through mid October, so book ahead.
Bear Lake Loop is the easiest trail in the park at just 0.7 miles with about 49 feet of elevation gain. It is flat, well marked, and great for families or anyone still adjusting to the altitude.
Emerald Lake Trail is a 3.6 mile round trip that passes three alpine lakes: Nymph Lake, Dream Lake, and Emerald Lake. The elevation gain is moderate at around 700 feet, but the payoff is one of the most photographed views in Colorado.
Sky Pond via Glacier Gorge is a tougher 8.7 mile round trip that climbs through subalpine forest to a stunning high altitude lake framed by jagged peaks. Plan on five to six hours for this one.
Longs Peak is the park’s biggest challenge. The Keyhole Route runs roughly 14.5 to 15 miles round trip with major elevation gain and exposed sections near the top. This hike is only for experienced, well prepared hikers who start before sunrise.
2. Garden of the Gods, Colorado Springs
Garden of the Gods is a free public park in Colorado Springs known for its massive red sandstone formations set against the backdrop of Pikes Peak. It holds more than twenty miles of trails, and most of them are considered easy to moderate, which makes it a great choice for families, beginners, and anyone short on time.
Perkins Central Garden Trail is a paved, wheelchair friendly 2.5 mile route that winds past the tallest rock formations in the park.
Siamese Twins Trail is an easy one mile loop that leads to a natural rock window with a striking view of Pikes Peak framed in the middle.
Palmer Trail connects several paths in the park and offers a moderate 2.5 mile route with wide open views across the entire formation.
Because the park sits at a lower elevation than the mountains, it is a smart place to hike during your first day or two in Colorado while your body gets used to the thinner air.
3. Maroon Bells, Aspen
The Maroon Bells are two of the most photographed peaks in North America, and the hikes around them are just as memorable as the postcard view. The area sits about ten miles from Aspen, and during the busy summer season you must take a shuttle from town rather than drive your own car to the trailhead.
Maroon Lake Scenic Trail is an easy walk of about 1.3 miles one way that circles the lake and offers the classic view of the twin peaks reflected in the water.
Crater Lake Trail extends the hike to roughly 3.5 miles round trip with a steady but manageable climb through aspen groves to a second, quieter alpine lake.
For a longer adventure, the West Maroon Pass Trail connects all the way to Crested Butte, a demanding route of about twelve miles that crosses a high alpine pass.
The best time to visit is late September, when the aspen trees turn gold, though this is also the busiest and most crowded time of year, so arrive early.
4. Hanging Lake, Glenwood Springs
Hanging Lake is one of Colorado’s most famous short hikes, located in White River National Forest near Glenwood Springs, right off Interstate 70. The trail covers about 3.1 miles round trip with roughly 1,000 feet of elevation gain in a short distance, so it earns its reputation as a hard workout despite being fairly short.
The lake sits in a fragile geological formation, and swimming or stepping into the water is not allowed. Because the area is so sensitive, the Forest Service now requires a timed entry reservation for every visitor, which you can book online in advance. Bring good footwear since the trail includes large rocks and steep sections, and consider visiting on a weekday morning to avoid the biggest crowds.
5. Chautauqua Park and the Flatirons, Boulder
Chautauqua Park sits at the base of Boulder’s famous Flatirons rock formations and serves as the trailhead for about forty miles of hiking paths. What makes this spot special is how close it is to a major city. You can be hiking into the mountains within minutes of leaving downtown Boulder.
Chautauqua Trail is a gentle, family friendly path of about 1.2 to 1.5 miles that leads straight toward the Flatirons through open meadows.
First and Second Flatiron Trail is a moderately challenging 3.6 mile round trip that climbs to the base of the rock slabs, where you can often watch climbers scaling the vertical faces.
Royal Arch Trail is the area’s toughest and most rewarding short hike, a 3.4 mile round trip with about 1,400 feet of elevation gain that ends at a natural stone arch with sweeping views over Boulder.
Parking fills up fast on weekends, so plan to arrive early or use the city’s shuttle service during peak season.
6. Mount Elbert, Leadville
If you want to stand on the highest point in Colorado, Mount Elbert is your target. At 14,440 feet, it is the tallest peak in the state and the second tallest in the lower 48 states, trailing only Mount Whitney in California. Despite its height, Elbert is considered one of the more approachable fourteeners because the standard route is a straightforward hike rather than a technical climb.
The North Mount Elbert Trail covers about 9.3 to 9.8 miles round trip with roughly 4,500 feet of elevation gain, starting from a trailhead near 10,000 feet. Most hikers need seven to nine hours to complete the full climb.
Because the distance and elevation gain are significant, this is not a beginner hike. Experts recommend training on shorter peaks first and starting well before sunrise to avoid the afternoon thunderstorms that are common in the Colorado high country during summer.
7. Great Sand Dunes National Park
Great Sand Dunes National Park, located in southern Colorado, offers a completely different kind of hiking experience. Instead of forest trails, you climb enormous mounds of sand that rise against a backdrop of the Sangre de Cristo mountains.
High Dune stands roughly 699 feet above the surrounding valley floor and is one of the most popular routes in the park. There is no official marked trail since the dunes constantly shift, so hikers pick their own path up the ridgelines. Climbing through loose sand is more tiring than a typical trail, so plan for extra time and carry more water than you think you need.
For a longer trek, hikers can continue to Star Dune, one of the tallest dunes in North America, though this adds significant distance and effort. The best times to visit are early morning or evening, since the sand surface can reach extreme temperatures during summer afternoons.
Tips for Hiking in Colorado
Planning ahead makes a huge difference when hiking in Colorado, especially at higher elevations. Keep these points in mind as you build your itinerary.
- Give your body time to adjust. Altitude sickness can affect anyone, regardless of fitness level. Spend a day or two at a moderate elevation before attempting a high mountain hike.
- Start early. Colorado’s mountains often see afternoon thunderstorms in summer, especially above the treeline. Aim to finish exposed sections of a trail by early afternoon.
- Carry more water than usual. The dry mountain air and intense sun cause faster dehydration than most hikers expect.
- Check for permits. Popular spots like Rocky Mountain National Park and Hanging Lake require advance reservations during peak season.
- Layer your clothing. Weather can shift quickly in the mountains, even in July, so pack a warm layer and a rain shell.
- Respect wildlife and plant life. Stay on marked trails whenever possible, especially in fragile ecosystems like Hanging Lake and the alpine tundra above the treeline.
Conclusion
Colorado offers an incredible range of hiking experiences, from short paved walks in Garden of the Gods to the demanding climb up Mount Elbert. The best places to hike in Colorado are spread across the entire state, so your ideal trip depends on how much time you have, how comfortable you are with elevation, and what kind of scenery excites you most. Beginners will find plenty of rewarding, low effort trails around Boulder and Colorado Springs, while more experienced hikers can chase the state’s famous fourteeners or the alpine lakes tucked deep inside Rocky Mountain National Park. Whichever trail you choose, plan ahead, respect the altitude, and give yourself time to enjoy views that make Colorado one of the best hiking destinations in the country.
