Colorado trails sorted by skill level, from easy lake walks to fourteeners and multi-day routes, with notes on permits, altitude, and weather.
Colorado earns its reputation. The state has more fourteeners than any other in the country, hundreds of miles of wilderness trail, and terrain that ranges from high desert canyon country to alpine tundra above treeline. Finding the best hikes in Colorado is less about whether great trails exist and more about matching the right trail to your group, your fitness, and your timeline.
This guide covers trails across four skill levels, from short walks with big payoff to multi-day backcountry routes that demand real preparation.

Easy Hikes Worth the Drive
Easy does not mean boring in Colorado. Some of the most visually striking terrain in the state sits on well-maintained, low-elevation trails that work for families, beginners, and anyone who wants scenery without the suffer.
Emerald Lake Trail, Rocky Mountain National Park
The Emerald Lake Trail near Estes Park covers about 3.5 miles round trip with roughly 600 feet of elevation gain. You pass Nymph Lake and Dream Lake before reaching Emerald Lake, which sits below Hallett Peak. The trail is well-signed and heavily used. Get there early before the parking area fills. Timed entry permits apply during peak season, so confirm current requirements with the National Park Service before you go.
Lower Cataract Lake Trail, Dillon
This short loop near Silverthorne runs about 2 miles and stays near 9,000 feet. The lake views are immediate, the trail is mostly flat, and it works well for groups with young children or dogs. It connects to longer routes if you want to extend the day.
Hanging Lake, Glenwood Canyon
Hanging Lake is one of the most photographed spots in Colorado. The trail is only about 2.4 miles round trip, but it gains 1,000 feet in a short distance, which puts it at the upper edge of the easy category. The lake itself, perched above a travertine shelf, is genuinely striking. Permits are required and fill fast, so book well in advance through the reservation system.
Moderate Hikes for Confident Day Hikers
These trails ask more of you: longer distances, more elevation, or terrain that requires some attention underfoot. They reward the effort.
Grays and Torreys Peaks, Clear Creek County
Grays Peak at 14,270 feet and Torreys Peak at 14,267 feet are two of the most approachable fourteeners in the state and are often done together in a single day. The standard route from Bakerville covers about 8 miles round trip with 3,000 feet of gain. The trail is well-worn and non-technical, but the altitude is real. Start before sunrise: afternoon thunderstorms build fast above treeline. This is a strong first fourteener for hikers who are acclimatized and fit.
Booth Falls Trail, Vail
The Booth Falls Trail climbs about 2,000 feet over 4 miles one way to reach a 60-foot waterfall and, if you continue, a high alpine basin. The lower section through aspen and spruce forest is worth the walk even if you turn around at the falls. The upper basin is excellent in late summer when wildflowers are at peak.
Petroglyph Point Trail, Mesa Verde National Park
Mesa Verde is primarily a cultural site, but the Petroglyph Point Trail offers a different kind of moderate hike: 2.4 miles of canyon rim walking with Ancestral Puebloan rock art along the route. Ranger-led tours are available for some areas, and the park requires permits for certain cliff dwellings. Check current access rules with the park directly.
Difficult Hikes for Experienced Hikers
These routes involve significant elevation gain, exposed ridgelines, off-trail navigation, or high altitude. They are not appropriate for beginners, and most require an early start.
Longs Peak, Rocky Mountain National Park
Longs Peak at 14,259 feet is the only fourteener inside Rocky Mountain National Park and one of the most demanding non-technical summit routes in Colorado. The Keyhole Route covers about 15 miles round trip with 5,100 feet of elevation gain. The upper section involves scrambling across exposed ledges and a steep couloir called the Homestretch. Most hikers start at 3:00 or 4:00 a.m. to summit before midday storms. Permits are required for overnight camping at the trailhead area. This is a serious day hike.
Maroon Bells Four Pass Loop, Aspen
The Four Pass Loop is widely considered one of the finest backpacking routes in the American West. The 26-mile circuit crosses four passes above 12,000 feet and circles the Maroon Bells Wilderness. Most hikers take three to four days. The scenery is exceptional throughout, but the route is demanding: cumulative elevation gain exceeds 7,000 feet, and weather above treeline can change in minutes. Camping requires a permit, and the Maroon Bells area has specific regulations around campfire use and bear canister requirements. Verify current permit availability with the White River National Forest before your trip.
Mount Sneffels, Ouray County
Mount Sneffels at 14,158 feet is one of the most photogenic fourteeners in the San Juan Mountains. The standard route from Yankee Boy Basin covers about 5 miles round trip with 2,900 feet of gain. The upper section involves Class 2 and Class 3 scrambling on loose rock. The approach road to Yankee Boy Basin is rough: high-clearance is required, and some sections are 4WD only. Confirm road conditions before you drive up.
Backcountry and Multi-Day Routes
If a single day is not enough, Colorado has wilderness areas and trail systems that support multi-day adventures at a serious level.
Weminuche Wilderness, San Juan Mountains
The Weminuche Wilderness covers over 499,000 acres in the San Juan and Rio Grande National Forests, making it the largest wilderness area in Colorado. The Continental Divide Trail passes through it. Popular entry points include Durango, Silverton, and Creede. Multi-day routes here involve real route-finding, creek crossings, and sustained high-altitude travel. Water is generally plentiful but needs treatment. Most of the wilderness has no maintained campsites, so know your Leave No Trace principles and how to select a site that meets land agency regulations.
Colorado Trail, Denver to Durango
The Colorado Trail runs nearly 500 miles from Waterton Canyon near Denver to Durango, crossing eight mountain ranges and six wilderness areas. Most thru-hikers take four to six weeks. But the trail is also excellent for section hiking, and many segments work as three- to five-day trips. The Collegiate Peaks section between Salida and Twin Lakes is a strong choice for a first multi-day segment: well-marked, scenic, and logistically manageable with resupply in Buena Vista.
If you are planning a multi-day backcountry trip in Colorado and want help thinking through route selection, the best backpacking trails in the USA guide covers how to approach it across skill levels.
Planning Considerations Before You Go
Altitude and Acclimatization
Most Colorado trailheads sit above 8,000 feet. If you are traveling from lower elevation, plan at least one or two days at altitude before attempting demanding routes. Symptoms of altitude sickness include headache, nausea, and fatigue. Descending is the only reliable treatment.
Permits and Access
Permit requirements in Colorado have expanded significantly in recent years. Rocky Mountain National Park, the Maroon Bells area, Hanging Lake, and many wilderness areas now require advance reservations for day use, camping, or both. Check with the relevant land agency (the National Park Service or the U.S. Forest Service) for current requirements. Do not assume last year's rules still apply.
Dogs on Trail
Colorado trails vary widely on dog policies. National parks generally prohibit dogs on trails. National Forest and BLM land is usually more permissive, but leash rules and seasonal restrictions apply. If your group includes a dog, the best dog-friendly hiking trails in North America guide covers what to look for before you commit to a route.
Topographic Maps and Navigation
Above treeline, trails can be faint or unmarked. Knowing how to read a topo map is a practical skill for any Colorado hike above 11,000 feet. If that is new territory for you, the guide to reading topographic maps for backcountry travel is a useful starting point.
Weather Windows
Colorado's afternoon thunderstorm pattern is predictable and dangerous. Plan to be below treeline by noon on any exposed route. July and August are the most active months for lightning. Early season (May and June) often means snow on high passes. Late season brings stable weather and fall color in September and October, but shorter days.
Turning a Trail List Into a Coordinated Trip
Picking trails is the easy part. Connecting them into a trip that accounts for driving legs, where to sleep, where to fuel up, what needs to be booked in advance, and how the sequence fits your group's pace: that is where most planning stalls.
Xavier, the AI agent companion at Xploreum, takes your plain-language trip description and builds a personalized, day-by-day Xpedition in under a minute. Describe your starting point, the trails or areas you want to hit, your group size, skill level, and how many days you have, and Xavier organizes the driving legs, trailheads, campsites, fuel stops, and activities into one connected journey with an interactive map.
Xavier does not replace AllTrails or Gaia GPS for route navigation, and it does not complete bookings on your behalf. What it does is take the coordination work off your plate so you can focus on the hiking. If you have been comparing tools and wondering what else is out there, the AllTrails alternatives guide covers how different tools handle the parts of trip planning that trail apps do not.
Frequently asked questions
What is the easiest hike in Colorado with impressive scenery?
The Emerald Lake Trail in Rocky Mountain National Park is one of the best options. It covers about 3.5 miles round trip with manageable elevation gain and passes three alpine lakes. Hanging Lake in Glenwood Canyon is also visually striking, though it requires an advance permit and involves a steep climb.
What is the best fourteener for beginners in Colorado?
Grays Peak is widely recommended as the most accessible fourteener for first-timers. The trail is well-marked and non-technical, and you can add Torreys Peak on the same day if you are feeling strong. Start early to avoid afternoon thunderstorms.
Do I need permits for hiking in Colorado?
It depends on where you are going. Rocky Mountain National Park requires timed entry permits during peak season. The Maroon Bells area near Aspen has its own reservation system. Hanging Lake requires advance permits. Wilderness areas require permits for overnight camping but not always for day use. Verify current requirements with the land agency before your trip.
When is the best time to hike in Colorado?
Late June through early September is the primary hiking season for high-altitude routes. July and August offer the best trail conditions but also the most afternoon thunderstorms. September brings stable weather, fewer crowds, and fall color at lower elevations. Snow can persist on high passes into July in heavy snow years.
Is the Maroon Bells Four Pass Loop suitable for solo hikers?
It is a serious route for any hiker, solo or otherwise. The terrain is demanding, weather above treeline is unpredictable, and the route involves sustained high-altitude travel. Solo hikers should have prior multi-day backcountry experience, carry appropriate navigation tools, and leave a detailed trip plan with someone reliable.
Can I bring my dog on Colorado trails?
Dogs are not permitted on trails in national parks, including Rocky Mountain National Park and Mesa Verde. National Forest and BLM trails are generally more permissive, though leash requirements and seasonal closures apply. Check the specific rules for the trail and land management area before you go.
How do I plan a multi-day hiking trip in Colorado without spending hours on logistics?
Start with a clear picture of your route, skill level, and how many days you have. Then work out the driving legs, campsites, permit requirements, and resupply stops. Xavier at Xploreum takes a plain-language description of your trip and builds a day-by-day Xpedition that connects those pieces, including an interactive map with waypoints you can open in your preferred navigation app.
