Colorado has more good hiking than any one trip can cover — 58 fourteeners, four national parks’ worth of terrain packed into one state, and trailheads that range from a 20-minute drive from downtown Denver to a full day’s approach into wilderness. The trick isn’t finding a good hike here; it’s narrowing down which region actually matches your trip.
Here’s the best of each, organized by where you’re actually going to be.
Front Range (Denver / Boulder Area)
The easiest hikes to reach, and genuinely excellent despite the convenience — this is where most Coloradans actually hike on a random Saturday.
Chautauqua Park to Royal Arch (Boulder) — A ~3.4-mile round trip climbing straight into the Flatirons, ending at a natural rock arch with a view back over Boulder. Steep for its length but short enough to do before lunch.
Roxborough State Park — Red-rock fins and hogbacks that feel like a mini Garden of the Gods without the crowds, 30 minutes southwest of Denver. The Fountain Valley Loop (2.7 mi, easy) is the classic introduction; Carpenter Peak (6.5 mi, moderate) climbs above the formations for a full valley view.
Garden of the Gods (Colorado Springs) — Dramatic red sandstone spires you can hike among on an easy, mostly-flat trail network. Free entry, open year-round, and one of the few “wow” hikes in Colorado that’s genuinely accessible to anyone.
Devil’s Head — A short, steep 2.8-mile round trip to one of Colorado’s last staffed fire lookout towers, with 360° views over the Rampart Range. A great half-day trip that doesn’t require an alpine start.
Rocky Mountain National Park
The state’s marquee high-country hiking, close enough to Denver (90 minutes) for a day trip but big enough to fill a week. We cover this park in full depth separately — see our complete Rocky Mountain National Park guide for permits, timed-entry reservations, and the lesser-known spots most visitors skip.
Quick highlights if you only have one day: Sky Pond (9.4 mi, strenuous, waterfalls and a knife-edge scramble at the end) and Emerald Lake (3.6 mi, moderate, three alpine lakes in one hike) are the two that consistently deliver the most for the effort.
Sawatch Range & the 14ers (Central Colorado)
Colorado’s highest terrain, and the reason “peak bagging” is basically a state pastime.
Mount Elbert — Colorado’s tallest peak (14,440 ft) and, by fourteener standards, one of the more approachable ones — a long grind (~9-11 miles round trip depending on route) but a straightforward trail with no technical scrambling. The classic “first 14er.”
Quandary Peak — Often recommended as the single easiest 14er in the state, and one of the most crowded for exactly that reason. A well-defined 6.75-mile round trip trail with no exposure.
Maroon Bells (Crater Lake Trail) — You’ve seen the photo — the twin peaks reflected in Maroon Lake are the most photographed mountains in Colorado. The easy 3.6-mile round trip to Crater Lake gets you the view without the technical Bells traverse itself, which is genuinely dangerous and not a hike for most people. Requires a reservation for the shuttle/access road in summer.
Altitude matters here more than almost anywhere else on this list. Most of this region sits above 10,000 ft even at the trailhead. See our altitude sickness guide before attempting any 14er, especially if you’re coming from sea level.
The San Juans (Southwest Colorado)
The most dramatic range in the state, and — outside of a few famous trailheads — genuinely uncrowded compared to the Front Range or the I-70 corridor.
Ice Lakes Trail (Silverton) — Widely considered one of the most beautiful day hikes in Colorado: a turquoise alpine lake ringed by 13,000-foot peaks, ~7 miles round trip with a serious 2,600 ft of gain to earn it.
Blue Lakes Trail (Ridgway) — Three stacked alpine lakes below Mount Sneffels, each more dramatic than the last. ~8.5 miles round trip to the upper lake.
Multi-day option: for a full backpacking trip through this range rather than a day hike, see our Weminuche Wilderness Loop trip report — 5 days through some of the least-visited high country in the state.
Great Sand Dunes National Park (South-Central Colorado)
The strangest hiking terrain in the state, and worth the detour precisely because it doesn’t look like anywhere else in Colorado.
High Dune — There’s no marked trail (you just walk up the sand), roughly 2.5 miles round trip, and the payoff is a 360° view over North America’s tallest dune field with the Sangre de Cristo range behind it. Go early or late — the sand gets brutally hot midday in summer, and there’s zero shade.
When to Go
June-September is the safe window for anything above treeline (roughly 11,500 ft in Colorado) — snow can linger into June at higher elevations, and afternoon thunderstorms are a real hazard on exposed ridgelines from July through August. Start alpine hikes by sunrise and aim to be off any exposed summit or ridge by early afternoon.
Front Range and lower-elevation hikes (Roxborough, Garden of the Gods, Chautauqua) are hikeable nearly year-round, snow permitting.
