Best Day Hikes Near Denver
Denver is one of the best-positioned cities in the country for outdoor adventure. As New Englander’s we love being able to take quick weekend trips to Maine or the White Mountains of New Hampshire, but we envy the easy access to “real” mountains that Denver offers. The Rocky Mountains aren’t a weekend trip from here — they’re practically in your backyard. Within an hour or two of downtown, you can be standing at the edge of a permanent snowfield, summiting a fourteener, or watching waterfalls spill into turquoise alpine lakes. Here are ten of the best day hikes within a 1–2 hour drive of Denver.
1. St. Mary’s Glacier — Idaho Springs (~1 hr)
One of the most iconic short hikes in the Denver area, and the one to do if you’re limited on time. I did this hike on a quick trip to Denver and absolutely loved it. The trail climbs steeply through pine forest before opening onto a subalpine lake whose mirror surface reflects the permanent snowfield above — and yes, snow sticks year-round, meaning you can watch snowboarders carve turns in the middle of July. The lake alone is worth the trip; push past it for sweeping Rocky Mountain views to the west. Ambitious hikers can continue all the way up to James Peak for a serious 8-mile day.
1.5–2.5 miles, ~1,100 ft gain.
2. Mount Bierstadt — Guanella Pass (~1 hr 15 min)
The closest fourteener to Denver and widely considered the most accessible — though it’s still a serious undertaking. The trail winds through wildflower meadows in July before breaking above treeline into rocky tundra, topping out at 14,060 feet with 360° views of the Continental Divide and neighboring peaks like Grays and Torreys. Start before sunrise to beat the afternoon storms.
7 miles, ~2,850 ft gain.
3. Grays & Torreys Peaks — Bakerville (~1 hr 10 min)
Want to bag two fourteeners in a single day? This is your trail. Both Grays (14,270 ft) and Torreys (14,267 ft) are accessible from the same trailhead off I-70, and the ridge connecting them makes a double summit very doable for fit, experienced hikers. No technical skills required, but the altitude is unforgiving — plan an alpine start and be off the summits well before noon. Even the approach through Stevens Gulch is worth the drive on its own.
6.7 miles, ~2,631 ft gain.
4. Dream Lake & Emerald Lake — Rocky Mountain National Park (~1 hr 45 min)
Starting from Bear Lake, this trail strings together three stunning alpine lakes — Nymph, Dream, and Emerald — each more beautiful than the last. Dream Lake is arguably the most photographed scene in Colorado: perfectly framed by Hallett Peak and Flattop Mountain, its glassy surface makes every photo look effortless. Emerald Lake, tucked into a glacial cirque at the end of the trail, earns its name with striking turquoise water. One of the most rewarding moderate hikes in the American West.
3.6 miles, ~650 ft gain.
5. Alberta Falls & Mills Lake — Rocky Mountain National Park (~2 hrs)
Also launching from Bear Lake, this route takes you past the 30-foot cascade of Alberta Falls before continuing into Glacier Gorge toward Mills Lake, an alpine gem backed by Pagoda Mountain, Chiefs Head Peak, and Thatchtop Mountain — a trio of summits that makes you feel genuinely small in the best possible way. A step up in distance from the Dream Lake trail, but rewards with a wilder, less-crowded feel once you’re past the falls.
5.3 miles, ~950 ft gain.
6. Herman Gulch — Idaho Springs (~1 hr)
One of the great wildflower hikes in Colorado, and surprisingly underappreciated given how close it sits to the interstate. The trail begins in forest, the highway noise fades within minutes, and before long you’re climbing through open meadows packed with color in mid-July before breaking above treeline into a stark alpine landscape surrounding Herman Lake. A solid step up in challenge from St. Mary’s Glacier, but still very manageable for a fit hiker.
6.3–8 miles, ~1,800–2,100 ft gain.
7. Royal Arch — Chautauqua Park, Boulder (~45 min)
The payoff hike of the entire Flatirons system. The trail climbs steeply from the iconic Chautauqua trailhead — with stone steps and some light scrambling — through tilted sandstone formations before arriving at a massive natural rock arch framing panoramic views of Boulder and the plains beyond. Don’t be fooled by the short mileage; the elevation gain is relentless. Plan 3–4 hours.
3.4 miles, ~1,400 ft gain.
8. Devil’s Head Fire Lookout — Rampart Range (~45 min)
A moderately paced trail through ponderosa pine that ends at an active fire lookout tower perched atop the Rampart Range — with views stretching all the way to Pikes Peak on a clear day. The 143-step climb to the top of the tower is a fun bonus, and if the ranger is in, they’re usually happy to talk. A great option when you want serious views without a serious suffer-fest.
4.3 miles, ~600 ft gain.
9. Hanging Lake — Glenwood Canyon (~2 hrs)
One of the most visually striking destinations on the entire Front Range. A travertine lake perched on a cliff ledge, fed by waterfalls that appear to spring directly from the rock face, with water so clear you can watch trout hovering in the current. The trail is relentlessly steep up Deadhorse Creek, but the destination is unlike anything else within two hours of Denver. Factor in the mandatory shuttle from Glenwood Springs and make a full day of it.
2.4 miles, ~1,000 ft gain.
10. Eldorado Canyon — Eldorado Springs (~35 min)
Dramatic, colorful canyon walls rising straight from a rushing creek — and most Denver locals have never been. Eldorado Canyon is a world-class rock climbing destination that also happens to have excellent hiking, with steep trails that gain elevation fast and deliver big views for the effort. The canyon setting is visually arresting in a way that surprises most first-timers. Finish with a stop in the tiny, quirky town of Eldorado Springs.
3.5 miles, ~1,200 ft gain.
