Fern Lake in Rocky Mountain National Park

“Ultimately, it is your commitment to the process that will determine your progress.” James Clear, author of Atomic Habits.

I still can’t believe my 6-year-old and 8-year-old daughters hiked the 7.6-mile roundtrip trek up to Fern Lake in Rocky Mountain National Park AND enjoy it.

We’ve been coming to Rocky Mountain National Park since they were babies. For a long time, it felt like we would never be able to hike beyond a mile or two. That’s one of the reasons I liked the Fern Lake trail when they were younger. There are several destinations along the way including Arch Rocks, The Pool, and Fern Falls. I’ve posted pictures of each below. When we had a fussy baby, or an impatient toddler, we could turn around at these points and still feel like we accomplished something.

Another reason I like the Fern Lake trail is because it tends to melt out earlier in the season compared to other higher hikes. The trail begins at 8,155 ft.

In early June, we spotted several elk and moose. Spotting three moose on a trail was a first for us. Other hikers who posted on AllTrails.com also reported ‘moose traffic jams’.

Arch Rocks

Between the animal spotting and wildflowers, the trail was wonderful even before we arrived at Arch Rocks. The journey to Arch Rocks is 1.2 miles from the trailhead.

The trail follows the Big Thompson River. In spring and early summer, it is common to spot extra waterfalls flowing in.

The pool

At 1.7 miles from the trailhead, you reach a wooden bridge that crosses over The Pool. This destination is one of our favorite 2-4 mile hikes in the park.

We continued beyond The Pool to Fern Falls which is a little under a mile and gains 400 feet of elevation.

This section of the hike gets pretty sad because a lot of the forest was damaged by wildfires.

Fern Falls

I wish I could insert a special effect that would allow you to feel the cool mist. Even a video of Fern Falls doesn’t do it justice.

We’ve never made it past Fern Falls, but after a quick snack break, we decided to continue hiking up to Fern Lake. There were small patches of snow along the way, but we were able to do it without equipment beyond waterproof hiking boots. Hiking poles would have been helpful in some spots.

Our girls love hiking in snow! We packed layers that we could easily take on and off along the trail as we went. The temperature dropped noteably right before we reached Fern Lake. We gained a total of 1,380 feet of elevation.

I love hiking to lakes in Rocky Mountain National Park, and this new-to-me lake was stunning.

My older daughter’s advice to kids who want to hike is ‘Don’t give up. Keep on trying – it will be worth it.’

On our way back down the trail, we spotted a couple moose and a elk. Can you see the elk hidding among the trees in the photo of my daughter below? When I asked her advice to other kids who want to hike she said, ‘there is still beauty on the way down’.

This Father’s Day weekend, we want to give a gold star to my husband whose ‘commitment to the process’ is starting to pay off. We appreciate him getting us out in the mountains and among the trees!

How do you get to Fern Lake Trailhead?

The National Park Service provides directions to the trailhead as:

From Beaver Meadows Visitor Center follow Hwy 36 west to Bear Lake Road (approximately 1.3 miles). Turn left onto Bear Lake Road and follow for 1.3 miles, then turn right onto Moraine Park Campground Road. After a short distance turn left at a sign indicating that Riding Stable and Trailheads are ahead. This road will take you along the edge of Moraine Park to the TH. The TH is at the end of the road.

What entrance should I use into Rocky Mountain National Park?

As of 6/16/23: NPS states that Fall River Entrance to Rocky Mountain National Park is under construction so only one lane is open to enter. Visitors are encouraged to avoid the Fall River Entrance and use the Beaver Meadows Entrance via U.S. Hwy 36.

Do I need a reservation to hike in Rocky Mountain National Park?

The Fern Lake hike is in the Bear Lake Corridor, so you must have both a pass into the park and a timed-entry permit called Park Access Plus between 5am and 6pm. The reservations can be made at Recreation.gov. Reservations typically open a month in advance. Some of the reservations open up the night before at 5:00 pm. When we are hoping to get a pass for the next day, we set an alarm on our phone so we can get on the site right at 5:00 before they all sell out. This video helps explain the system in more detail.

Where should I go if I can’t get a Park Access Plus reservation?

There are a lot of great options! Some of our favorites include:

Lily Lake, Gem Lake, Calypso Cascades in Wild Basin, Deer Mountain, Twin Sisters Peaks, or the Ute Trail.

Save the Date! August 25th is the National Park Service’s birthday and that means entrance fees are waived in all U.S. national parks including Rocky Mountain National Park.

Rocky Mountain National Park Entrance Fee

Typically, the daily entrance fee for one vehicle is $25. You can buy an annual RMNP pass for $70. Our family buys an ‘America the Beautiful’ annual National Parks and Federal Recreation Lands pass which is $80. This is a great deal for us because we go to Rocky Mountain National Park often, and we also like visiting nearby Indian Peaks Wilderness Area which is managed by the U.S. Forest Service. Seniors, members of the military, and 4th grade students may be eligible for discounts. You can learn more about these and other pass options online on the national park service’s website.
