Rocky Mountain National Park is one of the most beautiful places in the United States. Millions of visitors come each year to see incredible mountain scenery, waterfalls, elk, frozen lakes, go rock climbing, or to simply drive over one of the most stunning roads in the country. Living in Colorado has enabled our team to test out a larger portion of the hikes in the park. Here is our list of top hikes organized by difficulty. For each hike, we also have a link to our article with all the info you need to head out on the trails for that spot.

Best Easy Hikes In Rocky Mountain National Park
Dream Lake – Elevation: 9,905 Feet (3,019 M)
Dream Lake is simply stunning. It features incredible views of Hallett Peak, stunning trees, wildlife can often be found, and even great fishing. The trail features a gradual gain and only gets relatively steep in the last portion of the hike. This is a must do hike for anyone heading to Rocky Mountain National Park.
You’ll find many that park at this parking area and walk around Bear Lake as well. This is even simpler, but still had great views. For information on Bear Lake, see here:
Dream lake is often combined with Emerald Lake, which is on our list below in the intermediate level hikes.

Bierstadt Lake is less traveled compared to some of the other lakes in the area, but still highly trafficked. It features a simple but relatively steep trail that rises quickly to the lake where you get outstanding views of the surrounding peaks and the lake. While this lake alone is gorgeous, the same trailhead can be used in winter for access to lots of great cross country skiing.

Ouzel Falls – Elevation – 9,400 Feet (2887.07 Meters)
Ouzel Falls is located on the southeastern end of Rocky Mountain National Park and features well maintained trails along the gorgeous North Saint Vrain Creek.

Alberta Falls – Elevation: 9,400 Feet (2865 Meters)
Alberta Falls is on the way to Mills Lake, Loch Vale, and many other gorgeous lakes. We therefore had to put this on the list as one of the best easy hikes. You’ll reach the falls in less than a mile, and likely should continue on to some of our intermediate and difficult hikes if you are feeling up for the challenge.
Read our guide to Mills Lake, Loch Vale, or others to get the information to hike to Alberta Falls.

Best Intermediate Level Hikes In Rocky Mountain National Park
The Loch (Loch Vale) – Elevation: 10,190 Feet (3,105.9 M)
This hike is another one of those absolute must hikes in Rocky Mountain National Park. Getting to Loch Vale is beautiful because you pass right on by Alberta Falls, quickly get to insanely beautiful views for an amazing lunch spot, and then are right at the junction of many of the other top hikes in Rocky Mountain National Park (many on this list). So, if you are feeling really great when you reach Loch Vale, you can choose to continue on to some other awesome lakes or peaks.
Trail: Glacier Gorge Trailhead or Bear Lake Trailhead
Distance: 5.7 miles miles round trip (9.17 km)
Elevation Gain: 1,040 feet (316.99 meters)
Duration: 3-5 hours
More Hiking Information: Hiking Loch Vale
Emerald Lake – Elevation: 10,110 Feet (3,081.5 M)
As stunningly gorgeous as Dream Lake is, we highly recommend walking just a touch further and visiting Emerald Lake. The views get even more stunning as hikers sit just below massive cliffs, with an incredibly blue lake just in front. This is absolutely worth the extra effort.
This trail is also located at the end of Bear Lake Road.

Odessa Lake – Elevation: 10,055 Feet (3,064.8 Meters)
Odessa Lakes is one of the coolest lakes in RMNP due to “Little Matterhorn” which looms over the lake. The stunning surrounding mountains combined with beautiful trees make this hike really gorgeous in all seasons. This is a horse riding destination, has fishing along the Big Thompson River and at the lake, an awesome boulder field, and more. It also has multiple routes, and easy access to nearby lakes.
This lake we kept in the intermediate category, but it is just border of the hard/difficult category. We kept it here because it has less than 2,000 feet of elevation gain, but this is the hardest hike in the intermediate category. Fern Lake, another on our list, is on the way to Odessa.
Trailhead: Fern Lake Trailhead or Bear Lake Trailhead
Distance: 8.9 miles miles round trip (14.32 km)
Elevation Gain: 1,900 feet (579.1 meters)
Duration: 5-7 hours (book time)
More Hiking Information: Hiking Odessa Lake
Mills Lake – Elevation: 9,940 Feet (3,029.7 M)
Mills Lake features stunning views of Longs Peak, and easy access to many of the other hikes on our list. With rocks to lay out on, beautiful trees, and wide open views, this is certainly a top destination in the park. The trail is easy to follow, doesn’t feature too much elevation gain, and is well marked.
Trailhead: Glacier Gorge Trailhead or Bear Lake Trailhead
Distance: 5.6 miles miles round trip (9.01 km)
Elevation Gain: 780 feet (237.7 meters)
Duration: 3 to 5 hours (book time)

Lake Haiyaha features stunning surrounding peaks, deep water, and incredibly beautiful boulders surrounding the lake which make for perfect sitting areas, fishing spots, or lake jumping spots. The hike to the lake is beautiful, but the scenery within Chaos Canyon at this lake is simply stunning. This is another must do hike in this park.

Fern Lake – Elevation: 9,540 Feet (2,907.8 meters)
Fern Lake is often combined with Odessa as you have to hike passed Fern Lake depending upon your trailhead location. We love this hike because of the sections along the Big Thompson River, a gradual gain most of the way, and then easy access to the nearby Odessa Lake.
Trailhead: Fern Lake Trailhead
Distance: 7.4 miles miles round trip (11.9 km)
Elevation Gain: 1,400 feet (426.7 meters)
Duration: 4 to 6 hours (book time)

Best Difficult Hikes In Rocky Mountain National Park
Chasm Lake – Elevation: 11,823 feet (3,603.7 meters)
Chasm Lake is one of the most beautiful alpine lakes you’ll come across. The diamond rock face of Longs Peak is striking. The massive surrounding cliffs will make you feel small and insignificant. The blue water will humble you. The hike is difficult, but well worth it. It is a gradual gain nearly the entire way except for the last quarter mile where things get a bit more difficult. If you like alpine lakes, this is a must do in RMNP.
It is gorgeous in all seasons, but the last push in winter can be icy, so good microspikes are necessary.
Trailhead: Longs Peak Ranger Station – 9,405 feet
Difficulty: Hard / Difficult
Distance: 8.4 miles round trip (13.52 km)
Elevation Gain: 2,500 feet (762 m)
Duration: 6 to 9 hours (book time)
More Hiking Information: Hiking Chasm Lake
Longs Peak – Elevation: 14,259 feet (4,346 meters)
Simply put, this list wouldn’t be complete without Longs Peak on it. People will travel across the country just to climb this 14er, and it is no simple task for many. It is difficult, but stunningly beautiful, and the tallest peak in Rocky Mountain National Park. Don’t take this hike lightly, arrive early to the trailhead, and only attempt in good weather. Be sure to read our full guide on this mountain. Hikers only have to detour a little bit to also hit Chasm Lake, another hike on this list. It has class 3 hiking, meaning scrambling is required. This is not a recommended hike for the beginner, or anyone afraid of heights.
Trailhead: Longs Peak Trailhead
Difficulty: Very Difficult
Distance: 15 miles round trip (24.14 km)
Elevation Gain: 5,370 Feet (1636.8 meters)
Duration: 12 – 13 hours on average
More Hiking Information: Hiking Longs Peak
Sky Pond – Elevation: 10,900 feet (3,322.3 meters)
Sky Pond takes hikers passed Alberta Falls and Past Loch Vale, two other hikes on this list. In addition, the views at sky pond are extremely unique and striking. You’ll find this alpine lake to be special. The trail here is gradual and relatively easy until the last push where the trail gets very steep and wet due to a waterfall. This means it is slippery, and very icy in winter months.
Trailhead: Glacier Gorge Trailhead or Bear Lake Trailhead
Difficulty: Hard / Difficult
Distance: 9.0 miles miles round trip (14.48 km)
Elevation Gain: 1,780 feet (542.5 m)
Duration: 6 to 8 hours (book time)
More Hiking Information: Hiking Sky Pond
Flattop Mountain – Elevation: 12,324 Feet (3,756 M)
Flattop Mountain is one of our top hikes due to the crazy stunning views hikers experience above treeline. Early on, hikers get views of Hallett Peak and Longs Peak, but later on the views only get better.
At one point, hikers stand atop a cliff looking down at Emerald Lake, another hike on this list. They then continue heading towards the Continental Divide, and have the option to continue further to Hallett Peak or turnaround. This is also a great winter or snowshoeing hike for those that want something more strenuous.
