Rocky Mountain National Park alone has more than 350 miles of hiking trails, while destinations such as Aspen, Colorado Springs, Glenwood Springs and the San Juan Mountains provide countless additional opportunities.
Whether you are a beginner looking for a relatively easy Colorado hiking trail or an experienced adventurer searching for a challenging mountain route, there is something for you.
Below are some of the best hiking trails in Colorado, selected for their scenery, popularity, variety and overall hiking experience.
Top Hiking Trails In Colorado
1. Emerald Lake Trail
Location: Rocky Mountain National Park
Distance: Approximately 3.6 miles round trip
Difficulty: Easy to moderate
Emerald Lake Trail is one of the best hikes in Colorado for visitors who want spectacular mountain scenery without committing to an extremely difficult climb.
Starting from Bear Lake, the trail takes hikers past Nymph Lake and Dream Lake before reaching Emerald Lake. The changing scenery makes the journey particularly rewarding. You get forests, mountain reflections, alpine water and dramatic peaks throughout the hike.
The trail reaches Emerald Lake beneath the impressive surrounding mountain walls, creating one of Rocky Mountain National Park’s classic landscapes. The National Park Service lists Emerald Lake at about 1.8 miles one way from Bear Lake, with roughly 605 feet of elevation gain.
Because of its manageable distance and spectacular scenery, Emerald Lake is particularly suitable for first-time visitors to Rocky Mountain National Park.
Why hike it: Beautiful alpine lakes, accessible distance and outstanding mountain scenery.
2. Sky Pond Trail
Location: Rocky Mountain National Park
Distance: Approximately 8.5–10 miles round trip depending on route measurement
Difficulty: Difficult
For experienced hikers, Sky Pond is one of the most spectacular hikes in Colorado.
The route begins near Glacier Gorge and takes hikers through forests and past waterfalls and alpine lakes before reaching Sky Pond. Major highlights include Alberta Falls, The Loch, Timberline Falls and Lake of Glass.
The final section becomes considerably more challenging, with steep terrain around Timberline Falls. COTREX describes the route as difficult, with approximately 4.25 miles of ascent to Sky Pond and about 1,792 feet of elevation gain.
The destination is worth the effort. Sky Pond sits beneath dramatic rock formations, creating an unforgettable alpine setting.
The National Park Service lists Sky Pond at 4.9 miles one way from Glacier Gorge Junction, with about 1,710 feet of elevation gain.
Why hike it: Waterfalls, alpine lakes, dramatic rock formations and an incredible mountain destination.
3. Hanging Lake Trail
Location: Glenwood Canyon near Glenwood Springs
Distance: About 2.4 miles round trip
Difficulty: Moderate
Hanging Lake is among the most distinctive hiking destinations in Colorado.
The relatively short trail climbs steeply through Glenwood Canyon to a spectacular lake positioned on a cliffside. The lake’s turquoise-green water, waterfalls and surrounding vegetation make it look almost unreal.
Although the hike is short, it should not be underestimated. The route is steep and rocky, making the elevation gain feel significant over a relatively short distance. Colorado’s official tourism website describes the trail as just over a mile in length each way and notes its steep, rocky character.
Hanging Lake is also a National Natural Landmark because of its unusual geological formation.
Visitors should plan ahead because reservations are required for the trail.
Why hike it: One of Colorado’s most unusual lakes and an excellent short-but-challenging adventure.
4. Crater Lake Trail at Maroon Bells
Location: Near Aspen
Distance: About 3.6 miles round trip
Difficulty: Moderate
The Maroon Bells are among the most recognizable mountain landscapes in Colorado. Their distinctive peaks rise dramatically above Maroon Lake, producing one of the state’s most photographed views.
The Crater Lake Trail takes hikers beyond Maroon Lake into the wilderness beneath the Maroon Bells. The combination of towering mountains, forest and alpine water makes this one of the best scenic hikes in Colorado.
The trail is relatively short compared with many Colorado mountain routes, but its elevation and terrain mean hikers should still be prepared.
Access to the Maroon Bells Scenic Area is controlled during the busy season, with reservations and shuttle arrangements used to manage visitors.
Why hike it: Incredible views of the Maroon Bells and a memorable alpine environment.
5. Perkins Central Garden Trail
Location: Garden of the Gods, Colorado Springs
Distance: 1.5 miles round trip
Difficulty: Easy
If you want to experience Colorado’s dramatic landscapes without tackling a mountain climb, the Perkins Central Garden Trail is an excellent choice.
Located in Garden of the Gods, the trail winds through enormous red sandstone formations. The contrast between the red rocks and the surrounding mountains creates a landscape very different from the high alpine scenery found elsewhere in Colorado.
The trail is relatively flat and accessible, making it suitable for families, casual walkers and visitors who want a scenic experience without significant physical demands.
The Garden of the Gods identifies Perkins Central Garden as an easy 1.5-mile round-trip trail with less than 30 feet of elevation rise.
Why hike it: Easy terrain, spectacular red-rock formations and excellent accessibility.
6. Mills Lake Trail
Location: Rocky Mountain National Park
Distance: Approximately 5.6 miles round trip
Difficulty: Moderate
Mills Lake is another outstanding Rocky Mountain National Park hike for people who want beautiful alpine scenery without attempting a major summit.
The trail begins at Glacier Gorge and travels through forests and mountain terrain before arriving at Mills Lake. The destination provides impressive views toward Longs Peak and the surrounding rock formations.
The National Park Service describes the view of Longs Peak and the Keyboard of the Winds from Mills Lake as one of the park’s finest.
With around 750 feet of elevation gain according to the park’s trail information, Mills Lake offers a good balance between physical challenge and scenic reward.
Why hike it: Excellent mountain views and a rewarding alpine lake destination.
7. Mount Bierstadt Trail
Location: Guanella Pass
Distance: Approximately 7 miles round trip
Difficulty: Difficult
Mount Bierstadt is an excellent choice for hikers who want to experience a Colorado 14er.
A “14er” is a mountain exceeding 14,000 feet in elevation. Mount Bierstadt reaches more than 14,000 feet and is considered one of the more approachable Colorado 14ers, although it should still be treated as a serious mountain hike.
The route involves significant elevation gain and high-altitude conditions. Weather can change quickly, and hikers need to account for altitude, exposure and potentially difficult terrain.
For experienced hikers looking for their first high Colorado summit, Mount Bierstadt can be an attractive option.
Why hike it: A challenging summit experience and spectacular high-altitude views.
8. Blue Lakes Trail
Location: Near Mount Sneffels Wilderness
Distance: Approximately 6 miles round trip
Difficulty: Difficult
Blue Lakes Trail is one of the most scenic hiking routes in Colorado’s San Juan Mountains.
The trail leads toward a series of alpine lakes surrounded by rugged peaks. The combination of blue water, rocky mountains and high-elevation scenery gives the hike a classic Colorado wilderness atmosphere.
This is a more demanding hike than many popular tourist trails, so hikers should be prepared for elevation gain and changing mountain weather.
Blue Lakes is especially attractive to experienced hikers who want dramatic scenery away from some of Colorado’s more heavily visited Front Range destinations.
Why hike it: Beautiful alpine lakes and spectacular San Juan Mountain scenery.
9. Manitou Incline
Location: Manitou Springs
Distance: Approximately 0.9 miles upward
Difficulty: Very difficult
The Manitou Incline is unlike most hiking trails in Colorado.
Rather than following a conventional mountain path, hikers climb a steep former railway route consisting of thousands of steps. The short distance is deceptive because the elevation gain is substantial.
This makes the Manitou Incline particularly popular with fitness enthusiasts, runners and hikers looking for a demanding workout.
It is not necessarily the best trail for someone seeking a relaxed nature walk. Instead, it provides an intense physical challenge combined with impressive views around Manitou Springs and Colorado Springs.
Why hike it: An extremely challenging workout and one of Colorado’s most famous uphill hiking experiences.
10. Garden of the Gods Ridge Trail
Location: Colorado Springs
Distance: About 0.5 mile loop
Difficulty: Moderate
Ridge Trail provides another way to explore Garden of the Gods while getting closer to the park’s dramatic rock formations.
Although short, the trail includes uneven terrain and some elevation changes. The reward is a closer experience with the enormous sandstone formations.
Garden of the Gods has around 21 miles of trails overall, ranging from beginner-friendly routes to more demanding options.
Ridge Trail is therefore an excellent addition to a broader Garden of the Gods hiking day.
Why hike it: Short route, impressive rock formations and panoramic scenery.
11. Ouzel Falls Trail
Location: Rocky Mountain National Park
Distance: Approximately 5.4 miles round trip
Difficulty: Moderate
Ouzel Falls is an excellent choice for hikers who enjoy waterfalls and forest scenery.
The trail begins in the Wild Basin area of Rocky Mountain National Park and passes through a beautiful mountain environment before reaching the waterfall.
According to the National Park Service, Ouzel Falls is about 2.7 miles one way and involves roughly 950 feet of elevation gain.
The journey is as enjoyable as the destination, with streams, trees and mountain scenery along the route.
Why hike it: Waterfall views, forests and a rewarding moderate hike.
12. Bear Lake Loop
Location: Rocky Mountain National Park
Distance: Less than 1 mile
Difficulty: Easy
Bear Lake Loop is one of the easiest ways to experience the beauty of Rocky Mountain National Park.
The short trail circles Bear Lake and provides views of surrounding mountains and forests. Because it is short and relatively easy, it is suitable for families, casual hikers and travelers with limited time.
The National Park Service lists the loop at approximately 0.7 miles with only about 20 feet of elevation gain.
It can also serve as a starting point for longer hikes in the Bear Lake area, including Emerald Lake.
Why hike it: Very easy, short and scenic.
13. Chasm Lake Trail
Location: Rocky Mountain National Park
Distance: Approximately 8.4 miles round trip
Difficulty: Difficult
Chasm Lake is a spectacular destination for experienced hikers seeking dramatic mountain scenery.
The route leads toward the base of Longs Peak and offers increasingly impressive views as hikers climb higher.
The National Park Service lists Chasm Lake at 4.2 miles one way with approximately 2,360 feet of elevation gain.
The combination of steep mountain walls, alpine terrain and the proximity of Longs Peak makes this one of the most impressive challenging hikes in the park.
Why hike it: Dramatic alpine scenery and spectacular views of Longs Peak.
14. Siamese Twins Trail
Location: Garden of the Gods, Colorado Springs
Distance: Approximately 1 mile round trip
Difficulty: Easy
Siamese Twins Trail is a short and accessible route with a particularly memorable natural feature.
The trail leads to two large rock formations positioned in a way that creates a natural window through which hikers can see Pikes Peak.
The official Garden of the Gods information describes the route as an easy 1-mile round trip with less than 150 feet of elevation gain.
This makes it a great option for visitors who want dramatic scenery without committing to a long hike.
Why hike it: Unique rock formations and a natural view of Pikes Peak.
15. Four Pass Loop
Location: Maroon Bells-Snowmass Wilderness near Aspen
Distance: Approximately 25–27 miles
Difficulty: Very difficult
For serious backpackers and experienced hikers, the Four Pass Loop is one of Colorado’s ultimate wilderness adventures.
The route crosses four major mountain passes and travels through the spectacular Maroon Bells-Snowmass Wilderness.
Unlike a short day hike, this is a multi-day adventure requiring careful preparation, appropriate camping equipment, food, navigation skills and an understanding of high-altitude wilderness conditions.
The scenery changes throughout the journey, with alpine meadows, rugged mountains, forests and high mountain passes.
Why hike it: A spectacular multi-day Colorado wilderness experience.
16. Flattop Mountain Trail
Location: Rocky Mountain National Park
Distance: Approximately 8.8 miles round trip
Difficulty: Difficult
Flattop Mountain is an excellent option for hikers looking for expansive views rather than a lake or waterfall destination.
The route climbs from the Bear Lake area into high alpine terrain. The National Park Service lists Flattop Mountain at 4.4 miles one way with approximately 2,849 feet of elevation gain.
At this elevation, weather and trail conditions can be very different from those at lower elevations. Hikers should therefore prepare appropriately.
Why hike it: Panoramic high-country scenery and access to the alpine environment of Rocky Mountain National Park.
17. Gem Lake Trail
Location: Rocky Mountain National Park
Distance: Approximately 3.2 miles round trip
Difficulty: Moderate
Gem Lake provides a shorter alternative for hikers who want a rewarding mountain hike without spending an entire day on the trail.
The route climbs through the Lumpy Ridge area before reaching Gem Lake. The National Park Service lists the trail at approximately 1.6 miles one way with around 1,000 feet of elevation gain.
The relatively short distance combined with significant elevation gain makes it a good workout.
Why hike it: Great views, manageable distance and a rewarding climb.
18. Alberta Falls Trail
Location: Rocky Mountain National Park
Distance: Approximately 1.2 miles round trip
Difficulty: Easy
Alberta Falls is one of the best short hikes in Rocky Mountain National Park.
The trail leads through forest to a powerful waterfall where Glacier Creek drops through a narrow rocky channel.
The National Park Service lists Alberta Falls at approximately 0.6 miles one way, making it roughly 1.2 miles round trip, with around 210 feet of elevation gain.
Its short length makes it an excellent choice for families and travelers who want to see a waterfall without committing to a long hike.
Why hike it: Short, accessible and scenic waterfall hike.
How to Choose the Best Hiking Trail in Colorado
Choosing the right Colorado hiking trail depends on your fitness level, experience, available time and desired scenery.
For beginners: Bear Lake Loop, Perkins Central Garden Trail and Siamese Twins Trail are excellent starting points.
For families: Emerald Lake, Alberta Falls and Garden of the Gods trails provide attractive scenery without requiring extreme endurance.
For waterfalls: Alberta Falls, Ouzel Falls and Hanging Lake are strong choices.
For alpine lakes: Emerald Lake, Mills Lake, Crater Lake and Sky Pond offer outstanding scenery.
For experienced hikers: Mount Bierstadt, Blue Lakes, Chasm Lake and Flattop Mountain provide substantially greater challenges.
For backpackers: Four Pass Loop offers a much longer wilderness experience.
Altitude is another important consideration. Colorado’s high elevation means that a trail that appears short on paper can feel significantly more difficult than a comparable hike at lower elevation. New visitors should allow time to acclimatize and should pay attention to weather conditions.
Best Time to Go Hiking in Colorado
The best hiking season depends heavily on elevation and location.
Late spring and summer are generally popular for lower-elevation trails, while many high mountain routes become more accessible during summer after snow conditions improve.
Fall can be particularly beautiful because Colorado’s forests develop vibrant golden colors. However, conditions can change rapidly at higher elevations.
Winter hiking is possible on many lower trails, but high-elevation routes can become significantly more dangerous because of snow, ice, cold temperatures and avalanche hazards.
Always check current trail conditions, weather forecasts and access requirements before beginning a hike. Rocky Mountain National Park, for example, maintains current hiking information and trail advisories.
Essential Tips for Hiking in Colorado
Colorado hiking can be extremely rewarding, but preparation is important.
Carry enough water and food for your planned hike, even if the route appears short. Wear appropriate footwear and bring extra layers because mountain weather can change quickly.
Sun protection is also important at high elevations. Use sunscreen, sunglasses and a hat.
Hikers should also start early when possible. Popular trailheads can become crowded, and afternoon thunderstorms are an important consideration during summer.
For demanding hikes, tell someone where you are going and when you expect to return. Do not underestimate the difficulty of a route simply because its mileage is relatively short.
Finally, respect Leave No Trace principles. Stay on established trails, pack out your waste, avoid disturbing wildlife and leave natural features exactly as you found them.
