The Top 10 Rocky Mountain National Park Hiking Trails

There are over 350 miles of trails in Rocky Mountain National Park, but here 10 of the top-ranked trails with their corresponding difficulty level.

Emerald Lake (Easy)

This 3.5-mile hiking trail gives visitors fantastic views of Emerald Lake (which unsurprisingly gets its name from its emerald colored waters). Craggy mountain peaks stretch along the outer rim of the lake, putting you in your own little world out in the middle of the mountains. This is a very popular hiking trail due to its easy difficulty level.

Bear Lake (Easy)

This nature trail is less than a mile long and is a great way to see a gorgeous alpine lake. Tall, thin pines, aspen, and firs line the lake’s shoreline as mountains loom in the near distance. Sit on one of the benches around the lake to relax and take in a deep breath of fresh mountain air.

Lily Lake (Easy)

Lily Lake is another excellent option for those wanting great scenery with easy access. This .8-mile trail has several other trails that branch off from it, leading you to somewhat more challenging landscapes. The lake provides views of an endlessly rolling sea of alpine trees.

Sprague Lake (Easy)

Similar to Lilly Lake and Bear Lake, this wheelchair accessible trail is a great way to experience Rocky Mountain National park hiking and nature for guests of all ages and abilities.

Copeland Falls (Easy)

This .3-mile trail holds the breathtaking Copeland Falls at the end of this easy hike. A mix of large boulders, rushing water, and greenery surrounding the falls almost looks too beautiful to be real. There is a 1.1-mile trail that branches off around the side of the falls for more advanced hikers.

Gem Lake (Moderate)

A slight step up in hiking difficulty, the Gem Lake trail takes visitors on a 3.4-mile journey to glassy waters reflecting the odd rock formations surrounding the lake. On your way back, keep your eyes peeled for Paul Bunyan’s Boot, a rock structure resembling a giant shoe with a hole in the sole.

Finch Lake (Moderate)

Birding enthusiasts will love hiking this 4.5-mile trail leading up to the shores of Finch Lake. Local and migrating birds call the swampy shores of the lake home for portions of the year.

Fern Lake (Moderate)

This 3.8-mile trail is one of the more challenging hikes due to a section of the trail with a 1,275-foot rise. The expansive views of Notchtop and Little Matterhorn are well worth the challenge.

The Keyhole on Longs Peak (Difficult)

For those looking for a real challenge, Longs Peak trail will test your hiking skills. The views from these towering mountain tops are nothing short of spectacular as you look out across the Rockies. These peaks reach over 14,000 feet and the afternoons usually brings rain showers, so plan to hike this difficult trail in the morning.

Andrew Tarn and Andrews Glacier (Difficult)

This 4.6-mile trail hike takes you to a glacier-fed lake. You must climb over 2,000 feet in elevation to a total of 13,000 feet, making this a very strenuous hike.
