June 2, 2021

Rocky Mountain National Park is one of the crown jewel national parks. The scenery is spectacular. The crowds have grown, as they have at many national parks. “Rocky” as locals call it, is among the top 20 most popular national parks, right up there with legendary Yellowstone and Yosemite. More than 4.5 million people a year visit Rocky Mountain National Park.

So, if you join them, you will not be alone. But, you still can have a wonderful time in this beautiful place. What’s the key? Take one of these hikes in Rocky Mountain National Park.

As soon as you get a quarter mile or more away from a trailhead, the crowds will begin to thin out. Even toddlers and older folks can enjoy hikes on the beautifully maintained trails. So get out there!

Do be aware that reservations are required to enter Rocky Mountain National Park during the peak summer and fall months. A timed entry system started during the COVID-19 pandemic in 2020 and continues as a pilot program in 2021. Get more information on RMNP or make your reservation at RMNP.

Also, due to a wildfire in 2020, some trails in the park are closed. Get updates for the park and be sure to plan ahead.

Great hikes in Rocky Mountain National Park

Bear Lake

Easy. More of a stroll than a hike, Bear Lake is great for young children and people with compromised mobility. There’s a nature trail for young hikers and the young at heart. This hike is level, partially paved and it’s only half a mile around the lake. Start at the Bear Lake Trailhead. Do not consider driving to Bear Lake. You won’t find a parking place. Take the free shuttle bus (schedule)..

Nymph, Dream and Emerald Lakes

Easy. This hike to a trio of alpine lakes is one of the most popular in Rocky, so don’t count on any solitude. But, the ability to see three glacially carved lakes with spectacular views in such a short distance is worth the crowds. Bonus. You can see rare lily pads in bloom on Nymph Lake in mid-summer. Great hike for the whole family. Start at the Bear Lake Trailhead. Nymph is .5 miles up the trial. Dream is 1.1 miles up and Emerald is a 1.8-mile one-way hike. Elevation gain to Emerald Lake: 605 feet.

Alberta Falls is a great hike for the whole family. It’s just half a mile from the Glacier Gorge Trailhead and 0.8 of a mile from the Glacier Gorge bus stop. In the spring, the falls are the fullest, when the snow melts and roars through Glacier Gorge. Photo courtesy of the National Park Service.

Alberta Falls

Easy. A great hike in the spring, when the greatest volume of snowmelt is running through Glacier Gorge, this hike is a perfect, easy one for young children and older folks. Glacier Gorge Trailhead in the Bear Lake area. Get off the shuttle bus one stop before Bear Lake. The hike is only .8 miles one way. Elevation gain: 160 feet.

Copeland Falls, Calypso Cascades and Ouzel Falls

Moderate. Much like the Emerald Lake hike, this is a fun one because you see so much scenery over a relatively short distance. And you can check out a different area of the park known as Wild Basin. Parking can be difficult here because there’s no shuttle bus. Wild Basin Trailhead. Distance to Copeland Falls: .3 miles. Calypso Cascades is a 1.8-mile one-way hike and if you go to Ouzel Falls, it’s a 2.7-mile hike. Elevation gain to Ouzel Falls: 950 feet.

Lake Haiyaha

Moderate. This lake with the fun Native American name — meaning “big rocks” — can be part of a great loop hike. Start at Bear Lake. Hike to Dream Lake, then go left and hike 1.1 miles further to Lake Haiyaha. Enjoy relaxing on the giant boulders left here by a glacier. You can return the way you came for a total of 4.4 miles. Or, see new scenery and head back out to the Glacier Gorge Trailhead. You’ll pass Alberta Falls on the way out. Loop distance: 5.6 miles. Elevation gain from Bear Lake: 745 feet.

The Loch

Moderate. With its fancy name and beautiful scenery, The Loch is one of the most photographed lakes in Rocky Mountain National Park. As you hike up, you’ll see rugged cliffs and the remnants of a fast-disappearing year-round snowfield known as Taylor Glacier. One-way distance: 3.1 miles. Elevation gain: 990 feet.

Flattop Mountain

Difficult. Are you itching to do a 14-er, but you want some practice on a peak climb first? Then Flattop is a great choice for you. You’ll start at Bear Lake and will quickly leave the crowds behind as you climb higher and higher, eventually reaching an elevation of 12,324 feet. Start at Bear Lake. One-way to Flattop summit: 4.4 miles. Elevation gain: 2,849 feet. Click here for a map and information about Flattop Mountain.

Chasm Lake

Difficult. Longs Peak is the tallest in Rocky Mountain National Park. It’s also an extremely difficult and dangerous for non-experts to climb. If you want to enjoy a beautiful hike in the Longs Peak area, give Chasm Lake a try. It features great views of the sheer face of Longs Peak, known as “the diamond.” Click here for a map and more information about Chasm Lake. One-way distance from Longs Peak Trailhead: 4.3 miles. Elevation gain: 2,456 feet.

Lake Verna

Difficult. If you really want to escape crowds, locals call the west side of Rocky Mountain National Park the “wetter, better” side. Many of the trails on the west side begin near the old-west town, Grand Lake. For a very easy hike, try Adams Falls. For a beautiful, remote hike, continue on to Lake Verna. You’ll start at the East Inlet Trailhead. One way: 6.9 miles. Elevation gain: 1,809. Ambitious backpackers can get a permit to camp along the way. If you’re quite fit and are looking for a beautiful multi-day trip, you can hike above Lake Verna to Boulder-Grand Pass, then descend to Thunder Lake and hike out to the Wild Basin Trailhead. You would need permits, a bear container for your food and a ride back to Grand Lake.

Longs Peak

Extremely difficult. Not a walk-up. Like many of the 14-ers, Longs Peak has beckoned climbers for generations. But, you’ll need to be prepared. Those who attempt Longs Peak as a day climb need to have proper gear, plenty of food and water and need to start very early in the morning: by about 4 a.m. at the latest. It’s critical to be up and off the summit well before noon when summer thunderstorms roll in with dangerous lightning. Well above treeline, peak climbers don’t have anywhere to seek shelter from storms. One-way distance: 8 miles. Elevation gain: 4,855 feet. If you want to climb Longs Peak, study this information about the climb and consult with a climbing ranger at the Longs Peak Ranger Station.

Be prepared for your hikes in Rocky Mountain National Park

To hike or climb safely in Rocky Mountain National Park, you’ll need to keep an eye on the weather and bring proper gear. Some guidelines include:

  • Start early. Thunderstorms roar through the mountains nearly every day during the summer. Do not hike above treeline during a thunderstorm. Lightning can kill you. If you’re climbing high, get up and off your high point before noon.
  • Keep a close eye on children. Fast-moving streams and steep drop-offs can be dangerous. Rocky is a fun, but wild place. Don’t let children wander away.
  • Dress in layers. Wear sunscreen and a hat. Bring plenty of warm clothes and rain gear. Carry a map and a compass and wear sturdy footwear.
  • Bring plenty of food and water. Hikers in Colorado get very thirsty. And newcomers can deal with altitude sickness. Don’t let yourself get caught without enough hydration. Carry extra food and water in case of an emergency.
  • Never approach or feed wildlife: Obey wildlife closures and stay far away from any animals.
