If you’re visiting Rocky Mountain National Park (RMNP) for the first time, here’s the simple answer: the best beginner hikes are Bear Lake, Lily Lake, Sprague Lake, and Coyote Valley; the top intermediate trails are Emerald Lake and Alberta Falls; and the most rewarding challenges are Longs Peak, Sky Pond, and Flattop Mountain.
Add in some local favorites like Ouzel Falls or Copeland Falls, and you’ll experience the park the way both first-timers and seasoned Coloradans do.
RMNP is not one-size-fits-all. At 415 square miles, it offers gentle lakeside walks for families, half-day adventures for active hikers, and serious alpine climbs for those chasing altitude and solitude.
The trick is knowing which trails match your fitness, time, and expectations. Below, I break them down by skill level, with insider details, expert commentary, and the tips I’ve learned after decades of guiding here.
Gentle Trails That Deliver Big Rewards (Beginner Level)

You don’t need to be a mountaineer to enjoy the Rockies. The park’s beginner hikes are short, flat, and accessible, but still deliver postcard-worthy scenery.
Lily Lake is my top recommendation for first-timers. The 0.8-mile loop circles a sparkling alpine lake framed by mountain peaks.
It’s flat, easy, and perfect for spotting wildlife – moose sightings are common at dawn. I’ve seen entire families fall silent as a bull moose emerges from the willows to drink.
Sprague Lake proves that accessibility can be spectacular. The flat, 0.9-mile trail is wheelchair and stroller-friendly, yet the views rival any in Colorado. Photographers love it at sunrise and sunset, when the light turns the Continental Divide peaks gold.
Bear Lake Nature Trail is short (0.5 miles), paved, and perfect for multi-generational families. Kids love the interpretive signs, grandparents enjoy the easy access, and everyone leaves with memories of mountain reflections in the still water.
Coyote Valley Trail offers a one-mile stroll through wildlife-rich meadows along the Colorado River. At dusk, elk bugling fills the valley – a sound you’ll never forget.

Trails That Build Confidence (Intermediate Level)
Intermediate hikes are where many visitors discover their love of mountains. They’re not easy, but they’re not extreme either. They introduce elevation, moderate climbs, and big payoffs.
Emerald Lake Trail (3.2 miles round trip) is the most popular step-up hike. Along the way, you pass three lakes: Nymph Lake with its lily pads, Dream Lake with glassy reflections of Hallett Peak, and finally Emerald Lake, a jewel-colored basin beneath towering cliffs.
Each lake offers a natural “checkpoint,” making it flexible for families or groups with different energy levels.
Alberta Falls (1.6 miles round trip) is the park’s classic waterfall hike. The trail winds through fragrant pine forest and ends at a roaring 30-foot cascade. In late spring, snowmelt swells the falls into a thunderous spectacle. By late summer, it’s calmer but no less beautiful.
These trails are also excellent for building stamina. Many hikers “graduate” from beginner loops to Emerald Lake or Alberta Falls and leave with the confidence to tackle bigger challenges.

Epic Challenges for the Bold (Advanced Level)

For experienced hikers, RMNP offers true alpine challenges with altitude, scrambling, and exposure. These hikes require preparation, early starts, and respect for mountain weather.
Longs Peak (14,259 ft) is the park’s crown jewel. The 14.5-mile round trip gains nearly 5,000 feet and requires Class 3 scrambling near the summit. Only about 65% of attempts succeed due to weather and difficulty. It’s not a casual hike – this is mountaineering.
Sky Pond (8.4 miles round trip) takes you past Alberta Falls and Timberline Falls before ending in a glacial cirque that feels Himalayan. The final scramble beside Timberline Falls weeds out casual hikers, but those who make it are rewarded with one of Colorado’s most stunning alpine lakes.
Flattop Mountain (8.8 miles round trip) is a high-altitude trek without the technical difficulty of Longs Peak. At 12,324 feet, the tundra views of the Continental Divide are unmatched.
Chasm Lake (8.4 miles round trip) is another advanced favorite, tucked at the base of Longs Peak’s sheer east face.

Secret Spots Locals Love
Away from the main trailheads, there are quieter gems where you can hike in peace.
Ouzel Falls (2.4 miles) showcases nature’s resilience after the 2013 floods. The trail now passes a mosaic of habitats alive with birds, including the American dipper that nests behind waterfalls.
Copeland Falls (1.8 miles) is often overlooked, but its cascades rival the park’s most famous. Continue further to Calypso Cascades (3.8 miles) for even more solitude.
Estes Cone (6 miles), just outside the park, offers a steep but rewarding summit climb – and it’s dog-friendly, unlike trails inside RMNP.

How Seasons Transform the Park
Each season changes RMNP completely, turning familiar hikes into new adventures.
- Spring: Waterfalls like Alberta Falls are at their peak, but streams can swell dangerously fast.
- Summer: Wildflowers bloom across alpine meadows, but afternoon storms are frequent – start early.
- Fall: September brings golden aspens and elk rut season, with bulls bugling in valleys.
- Winter: Crowds disappear, trails like Bear Lake become magical under snowshoes, but conditions require spikes and layers.

Safety and Insider Tips
- Altitude: Even easy trails feel harder at 8,000–12,000 feet. Hydrate, pace yourself, and allow time to acclimate.
- Weather: Afternoon storms are the number one hazard. Start hikes by sunrise and aim to be below treeline by noon.
- Wildlife: Elk, moose, and even bears are common. Keep 75+ feet distance from elk and 120+ feet from bears.
- Navigation: Don’t rely solely on phone GPS – carry a map, compass, or GPS device.
- Shuttles: During peak season, use the free Bear Lake shuttle to skip parking stress.
