2. Mills Lake Trail

Named after a founder of the park, Enos Mills, the Mills Lake Trail gives you a chance to see everything that’s quintessential about the Rockies. As you travel along this 5-mile round trip trail, you’ll hike past waterfalls, stream beds, and a glacially carved gorge.

Insider Tip: You can access the Mills Lake trailhead at the Glacier Gorge parking lot. However, space is very limited and it often fills up quickly. To avoid this hassle, consider taking advantage of the park’s free shuttle.

6. Gem Lake Trail

Gem Lake lives up to its name as a hidden gem tucked away among granite domes in the Lumpy Ridge area. However, since it doesn’t have any inlet or outlet streams, Gem Lake is actually a shallow pond that’s filled only by snowmelt and rainfall.

You can access the Gem Lake Trail using the Lumpy Ridge Trailhead. To reach the lake, you’ll climb upwards for 2 miles using several switchbacks for a total elevation gain of 1,090 feet.

Along the way make sure you take some time to appreciate the views of Longs Peak, the Continental Divide, and Estes Park. Once you’re done enjoying Gem Lake, it’s just another 2 miles back to where you started.

7. Ouzel Falls Trail

You can hike to Ouzel Falls Trail using the Wild Basin Trailhead. As you hike along the trail, you’ll get to listen to the gentle babble of the North Saint Vrain Creek.

At about 5.4 miles round trip and 950 feet of elevation gain, this is a moderately difficult hike. However, the best part of the hike is that you actually get to enjoy several waterfall views along the way, including Lower Copeland Falls, Upper Copeland Falls, Calypso Cascades, and Ouzel Falls.

8. Emerald Lake Trail

The Emerald Lake Trail is one of the best hikes in Rocky Mountain National Park because you actually get to see four lakes — Bear Lake, Nymph Lake, Dream Lake, and Emerald Lake — over a relatively short distance.

The trail is 4.1 miles round trip and has a moderate elevation gain of 744 feet. You’ll start your hike at Bear Lake. At about a half-mile in, you will reach the charming Nymph Lake.

Hike another half-mile in, and you’ll reach Dream Lake. From this point, you’ll hike deeper into Tyndall Gorge before reaching Emerald Lake.

Once you’re here, be sure to take in the incredible sight of the jagged spires of Flattop Mountain looming over the crisp alpine lake.

9. Deer Mountain Trail

Although Deer Mountain Trail is 6 miles round trip and has an elevation gain of 1,083 feet, the hike to the 10,013-foot summit is a little easier thanks to the numerous switchbacks.

Your trek to the peak is uphill almost the entire way. Fortunately, you get to do it through a forest of fresh-smelling ponderosa pines, which makes the effort more enjoyable.

Once you reach the top, you’ll enjoy incredible views of Moraine Valley and the surrounding peaks.

10. Flattop Mountain Trail

The Flattop Mountain Trail is difficult and strenuous. However, it’s still considered one of the best hiking trails in Rocky Mountain National Park because it’s truly unique. After all, how many times can you say you hiked to the top of the Continental Divide?

The trail is 8.8 miles round trip and has an elevation gain of 1,215 feet. It starts at Bear Lake and rapidly gains elevation.

Along the way, you’ll have unbeatable views of Dream Lake, Emerald Lake, and Hallett Peak. Once you reach the summit, you have the notable opportunity to stand on top of the country’s dividing line.

From the top of Flattop Mountain, you can choose to continue along a faint, rocky trail to Hallett Peak. At 12,718-feet, Hallett Peak offers phenomenal 360° views of the surrounding area.
