1. Rocky Mountain National Park: The Crown Jewel of Colorado Hiking

It’s impossible to discuss the best places to hike in Colorado without starting with its most famous park. Rocky Mountain National Park (RMNP) is a sprawling 415-square-mile masterpiece of glacier-carved valleys, towering peaks, and abundant wildlife. With over 350 miles of trails, it offers everything from easy, paved walks to strenuous backcountry expeditions. The park’s high elevation—trails often start above 9,000 feet—means shorter oxygen and rapidly changing weather, but the rewards are unparalleled.

Must-Hike Trails in Rocky Mountain National Park

Bear Lake to Emerald Lake: This classic 3.6-mile round-trip is a perfect introduction to RMNP’s alpine beauty. Starting at the iconic Bear Lake (elevation 9,475 ft), the trail passes Nymph Lake and Dream Lake before reaching the stunning, milky-green Emerald Lake, framed by Hallett Peak and the Flattop Mountain escarpment. Go early to avoid crowds and catch morning light on the peaks.
Alberta Falls: A short, 1.6-mile round-trip hike from the Glacier Gorge Trailhead that culminates in a powerful, 25-foot waterfall. It’s family-friendly and showcases the park’s lush forest and creek-side scenery.
The Keyhole Route on Longs Peak: For the advanced hiker, this is a legendary Colorado objective. The 9.4-mile round-trip to the 14,259-foot summit is a classic fourteener involving exposed scrambling, the famous "Horseshoe," and a final push up the "Trough." It requires an alpine start (before dawn), technical skill, and a permit for camping in the backcountry zone. This is not a hike—it's a mountaineering route.
Trail Ridge Road: While primarily a scenic drive, this 48-mile highway—the highest continuous paved road in the U.S.—offers numerous short, high-alpine trailheads like the Tundra Nature Trail (0.6 miles) at the Alpine Visitor Center. Walking here feels like being on top of the world, with views of the Never Summer and Medicine Bow ranges.

Pro Tip: RMNP now requires timed entry permits for vehicles during peak season (May 26–October 22). Reserve yours months in advance on Recreation.gov. The park’s ecosystem is fragile; stay on the trail to protect the delicate tundra.

2. Garden of the Gods: Red Rock Wonderland in Colorado Springs

Imagine dramatic, 300-foot sandstone fins painted in shades of orange and red, set against the backdrop of snow-capped Pikes Peak. This is Garden of the Gods, a registered National Natural Landmark and one of the most visually striking and accessible hiking areas in Colorado. The park’s 1,300 acres are a geological storybook, with formations like the Kissing Camels and Balanced Rock telling a tale of 300 million years of uplift and erosion.

Exploring the Trails

Central Garden Trail (1.5 miles): The park’s most popular paved path is a flat, easy loop that winds between the major formations. It’s perfect for all abilities, strollers, and offers endless photo ops. The contrast of red rock, green grass, and blue sky is iconic.
Siamese Twins Trail (1.1 miles): A slightly more rugged, rocky path that leads to the fascinating Siamese Twins formation—two pillars connected at the base. The views of Pikes Peak from here are exceptional.
Ridge Trail (2.7 miles): For a moderate challenge with big payoff, this trail climbs steadily from the Central Garden to the park’s southern boundary, offering panoramic views of the entire park and the city of Colorado Springs below.
Permitted Activities: Unlike many parks, rock climbing is allowed on designated walls with a free permit. Watching climbers scale the sheer faces adds another layer of dynamism to your visit.

Key Insight: Garden of the Gods is free to enter and open from 5 a.m. to 10 p.m. year-round. Its low elevation (6,400 ft) makes it a great acclimatization stop if you’re heading to higher trails. The park’s visitor center has excellent exhibits on geology and ecology.

3. Maroon Bells-Snowmass Wilderness: The Postcard Peak of Colorado

If there’s one sight that defines Colorado’s alpine majesty in the public imagination, it’s the Maroon Bells. These twin peaks (Maroon Peak at 14,163 ft and North Maroon Peak at 14,019 ft) reflect perfectly in the still waters of Maroon Lake, creating the most photographed scene in the state. Located near Aspen, this wilderness area is part of the Elk Mountains and represents the quintessential high-mountain hiking experience.

The Iconic Maroon Lake Scenic Trail

Maroon Lake Scenic Trail (1 mile round-trip, paved): This easy, accessible path from the parking lot to the lake viewpoint is the must-do experience. For the best reflection photos, arrive before 7 a.m. in summer—the morning calm creates a mirror-like surface. Rangers often give talks here about the geology and ecology.
Crater Lake Trail (3.6 miles round-trip): A moderate hike that climbs 500 feet from Maroon Lake to Crater Lake, offering different, stunning perspectives of the Bells. The trail passes through aspen groves (spectacular in fall) and wildflower meadows.
Four Pass Loop: For the serious backpacker, this 26-mile circuit is a Colorado legend. It traverses four passes over 12,000 ft (West Maroon, Frigid Air, Buckskin, and Trail Rider), connecting pristine alpine lakes, meadows, and continuous 360-degree views of the Bells and Snowmass Mountain. It’s typically done in 3-4 days.

Important Note: Access to the Maroon Bells area is highly controlled. From late June to early October, a shuttle bus system is mandatory for all visitors (private vehicles are restricted). The fee supports trail maintenance and preservation. The area is also bear habitat—carry bear spray and know how to use it.

4. Great Sand Dunes National Park & Preserve: A Surreal Hike on Earth’s Dunes

Prepare for a hike unlike any other in Colorado. Great Sand Dunes National Park features the tallest sand dunes in North America, rising 750 feet from the valley floor against the backdrop of the rugged Sangre de Cristo Mountains. The contrast of desert-like dunes, alpine lakes, and wetlands creates a bizarre, beautiful landscape. Hiking here is less about elevation gain and more about unique sensory experience—the feel of sand, the sound of wind, the sight of rippling dunes.

Dune Adventures & Beyond

High Dune (2.5 miles round-trip, strenuous): This is the main event. You’ll hike up the steep, sandy ridge of the tallest dune. It’s a brutal workout—each step up is a step back down—but the 360-degree panorama from the top, with the dunes stretching to the horizon and mountains beyond, is unforgettable. Start early to avoid scorching sand and afternoon thunderstorms.
Zapata Falls (0.9 miles round-trip): A short, easy hike to a hidden 30-foot waterfall behind a rock wall. The trail is rocky and can be icy in winter. The cool mist at the falls is a welcome relief after dune trekking.
Mosca Pass Trail (7 miles round-trip): For a completely different ecosystem, this moderate trail climbs through pine forests and aspen groves to a 9,737 ft pass with views back to the dunes and into the Sangre de Cristo Wilderness. It’s a great way to see the park’s biodiversity.
Medano Creek: Seasonally (typically late April to June), this intermittent stream flows at the base of the dunes, creating a "surf zone" where you can wade, build sand castles, or even skimboard. It’s a unique, family-friendly feature.

Critical Advice: The sand gets extremely hot in summer. Wear closed-toe shoes (sandals are not enough), bring twice as much water as you think you need, and use sun protection. There are no services on the dunes. The park’s elevation is 8,200 ft, so take it easy if you’re acclimating.

5. The Colorado Trail: A Long-Distance Pilgrimage

Spanning 486 miles from Waterton Canyon near Denver to Durango, the Colorado Trail (CT) is arguably the state’s ultimate hiking experience. It traverses the entire length of the Rocky Mountains in Colorado, connecting six wilderness areas, crossing eight mountain ranges, and offering a profound journey through the state’s diverse landscapes—from ponderosa pine forests to high alpine tundra. Completing the entire trail is a major thru-hiking endeavor (typically 4-6 weeks), but you can easily sample its magic on section hikes.

Iconic Sections for Every Hiker

Segment 1: Waterton Canyon to Roxborough State Park (16.6 miles): A moderate start through canyon landscapes with red rock formations and wildlife viewing (bighorn sheep!).
Segment 6: Copper Mountain to Fremont Pass (13.5 miles): A stunning high-alpine hike above tree line, with views of the Tenmile Range and the massive Henderson Mine. It’s a great taste of the CT’s exposed, above-timberline terrain.
Segment 20: Molas Lake to Hermosa Creek (12.2 miles): Near Durango, this section offers southwestern mountain scenery, aspen groves, and creek crossings. It’s a beautiful, less-crowded finale.
Segment 28: San Juan Mountains (various): The CT’s southern sections through the San Juan Mountains are arguably its most dramatic, with rugged peaks, old mining towns, and vast meadows.

Planning Note: The CT is well-signed with blue and white diamonds. Most hikers go southbound (Denver to Durango) to acclimate gradually to elevation. The trail has numerous access points, making day hikes and weekend trips very feasible. The Colorado Trail Foundation provides detailed maps, guidebooks, and trail condition updates.

6. Hanging Lake: A Turquoise Treasure in Glenwood Canyon

A short but steep hike leads to one of Colorado’s most magical and fragile sights. Hanging Lake is a tranquil, turquoise basin suspended on the side of Glenwood Canyon, fed by waterfalls that spill over sheer cliffs. The 1.2-mile (each way) trail climbs about 1,000 feet via rocky steps and log bridges. Its popularity has exploded, leading to a strict reservation system.

The Hanging Lake Experience

The Hike: The trail is physically demanding for its length—those steps are relentless. But the reward is immediate: the stunning, still lake with its vibrant color (from limestone and algae) and the gentle sound of Spouting Waterfall. Swimming is strictly prohibited to protect the delicate ecosystem.
Reservation System: To manage crowds and protect the environment, all visitors must purchase a timed entry permit ($10 per person) from Recreation.gov, in addition to the Glenwood Canyon bike path fee if biking. The permit includes a mandatory shuttle from the Glenwood Springs rest area. No private vehicles are allowed at the trailhead.
Why the Fuss? Hanging Lake is a geological wonder—a "hanging" valley formed by glacial activity. The water’s color and clarity are otherworldly. The strict management ensures this pristine environment survives for future generations.

Visitor Tip: Combine your hike with a soak at Glenwood Hot Springs (the world’s largest mineral hot springs pool) just a few miles away. It’s the perfect recovery after the Hanging Lake climb.

7. Mount Evans (Byers, Sprague, and Summit Lakes): The Highest Auto Route in America

For those who want breathtaking high-alpine views without a multi-day climb, the Mount Evans Scenic Byway is unparalleled. This 28-mile paved road climbs from Idaho Springs to the 14,130-foot summit of Mount Evans, the highest auto route in North America. Along the way, you’ll find several fantastic hiking trailheads that put you right on the continental divide.

Hikes Along the Byway

Summit Lake to the Summit (0.75 miles one-way): From the parking lot at Summit Lake (12,830 ft), a short, steep, paved path leads to the actual summit. It’s a must-do for the 360-degree panorama of the Front Range, the Sawatch Range, and the Rocky Mountain National Park peaks. Be prepared for extreme wind and cold—even in summer.
Byers Peak Trail (7 miles round-trip): Starting at the Byers Peak Trailhead (around 11,500 ft), this moderate hike climbs to a false summit with incredible views of the Mount Evans massif and the Chicago Lakes basin below. It’s less crowded than the summit spur.
Sprague Lake Trail (1 mile round-trip): An easy, flat walk from the Sprague Lake campground to a stunning lake reflecting the east face of Mount Evans. It’s a beautiful, serene spot, especially at sunrise or sunset.

Altitude Warning: The summit is above 14,000 feet. The air is thin. Drink water constantly, move slowly, and know the signs of altitude sickness. The road is typically open from late May to October, weather-dependent. There’s a fee to drive the byway.

8. San Juan Mountains: Colorado’s Rugged and Remote Heart

Southwest Colorado’s San Juan Mountains are a geologically complex, rugged, and less-visited alternative to the Front Range. This range boasts more 14ers than any other in Colorado (38), deep canyons, ghost towns, and a palpable sense of history and remoteness. Hiking here often feels like true exploration.

San Juan Gems

Ice Lakes Basin near Silverton: A spectacular, moderate hike (6.4 miles round-trip) to a series of stunning, electric-blue alpine lakes fed by mineral-rich water. The trail climbs steadily through wildflower meadows (July-August is peak) with the dramatic peaks of the San Juans as your backdrop. The lower lake is the main attraction.
Wheeler Park Geologic Loop (4.6 miles): An easy to moderate loop near the historic mining town of Lake City that showcases bizarre volcanic rock formations, old mine shafts, and panoramic views. It’s a fascinating hike through a landscape shaped by fire.
The Alpine Loop Backcountry Byway: Not a single trail, but a 4x4 road network connecting Lake City, Silverton, and Ouray. It provides access to dozens of high-alpine trailheads for 14ers like Uncompahgre Peak and Handies Peak, as well as hidden lakes and meadows. You need a high-clearance, 4WD vehicle for most of it.
Molas Pass to Continental Divide Trail: A short hike from the Molas Pass turnout (on the Million Dollar Highway) to stand directly on the Continental Divide. It’s a quick, symbolic walk with immense views of the Uncompahgre Gorge.

San Juan Reality: Weather is extremely volatile. Afternoon monsoon thunderstorms are daily in summer. Start hikes by 7 a.m. to be below treeline by early afternoon. Cell service is nonexistent. Carry a map, compass, or GPS. This is true backcountry—be prepared.

9. Pikes Peak: The "Hill" That Inspired a Nation

"Pikes Peak or Bust!" was the rallying cry of gold seekers. At 14,115 feet, Pikes Peak is not the highest in Colorado, but it is arguably the most historically and culturally significant. The Barr Trail is the classic, non-technical hiking route to the summit, gaining about 7,800 feet over 13 miles one-way. It’s a brutal, full-day grind often compared to a marathon with altitude.

The Barr Trail Ascent

The Route: Starting in Manitou Springs, the trail winds through forests, crosses creeks, and offers incredible views back down the canyon. The final mile above tree line is exposed, rocky, and often windy. The summit house offers food, souvenirs, and a chance to see the "America the Beautiful" inspiration plaque.
Alternatives: The Cog Railway and Pikes Peak Highway (driving) are easier ways to reach the top. Many hikers do the Barr Trail as a downhill hike after taking the cog up, which is much easier on the knees but still requires good fitness for the descent.
Why It’s Special: The view from the summit is said to have inspired Katharine Lee Bates to write "America the Beautiful" in 1893. The sense of accomplishment on finishing the Barr Trail is profound.

Crucial Planning: The Barr Trail is unshaded for most of its length. Carry 3+ liters of water, electrolytes, and sun protection. Start before dawn to avoid afternoon lightning. Check the Pikes Peak Summit House website for current conditions and fees.

10. Trail Ridge Road: The High Road in Rocky Mountain National Park

We return to Rocky Mountain National Park, but this time to highlight its engineering marvel and a hike-drive combo. Trail Ridge Road is the park’s main artery, but its many pull-offs and trailheads create countless micro-adventures. The road itself climbs to 12,183 feet, offering views of the park’s alpine tundra ecosystem, which resembles the Arctic.

Short Hikes with Epic Views Along Trail Ridge Road

Tundra Nature Trail (0.6 miles): From the Alpine Visitor Center (the highest in the National Park System), this paved, interpretive loop is a must. You’ll walk on the actual tundra, see mountain goats and bighorn sheep, and learn about the hardy plants that survive the harsh conditions.
Forest Canyon Overlook: A short walk from the parking lot to a jaw-dropping viewpoint looking down into Forest Canyon and towards the Never Summer Mountains. It’s a quick stop with massive payoff.
Mummy Range View: Just east of the Milner Pass area, a small pull-out offers a perfect framed view of the rugged Mummy Range, including Ypsilon Mountain.
Lake Irene: A short walk to a beautiful subalpine lake, great for a picnic with a view of the Continental Divide.

Driving Note: Trail Ridge Road opens late May or early June (it’s snowed in the rest of the year). It’s a slow, winding drive with many narrow sections. Use pull-outs to let faster traffic pass. Watch for elk and other wildlife, especially at dawn and dusk.
