Description

Added by Tobin Akehurst

Hike up to two very tall Rocky Mountain National Park summits. Along the route, you'll see wildlife and abundant wildflowers as well as views of Keyhole Route and Longs Peak.

Arrive at the Bear Lake Trailhead. Follow abundant signage toward Flattop Peak. Once you arrive at the summit of Flattop identify the unnamed unmaintained trail leading south toward Hallett Peak. Round the head of Tyndall Gorge and ascend the rocky slopes toward the summit by connecting short use trails. Occasional cairns mark the way and the route is very easy to follow.

A rugged loop hike is possible by way of descending from Hallett peak into Chaos Canyon to reach the trail at Lake Hiayaho.

My dad, brother and I did this a while ago! Had a great time doing it, we got up plenty early and caught the sunrise from above the treeline. Overall a very good hike, and not too many people if you get out early in the morning.

Great two peaks for a day hike in the park. An alternative loop I've done with this hike includes adding Otis to Flattop and Hallets. From Hallets, Otis is a quick 10-20 min scramble along the ridge, Flattop-Hallets-Otis (FHO) is best done as a loop, descending from Otis and down Andrew's Glacier. The Andrew's Glacier trail puts you out at Glacier Gorge so you can either hike back to Bear Lake or take the shuttle.

This is actually a really fun hike. It will take some effort to get there from Bear Lake but definitely worth it.

I did this hike last June. Its a really nice hike with beautiful views of all of Rocky Mountain National Park and Longs Peak. It was a bit chilly and windy at the top, but was worth it for some beautiful views.

Photograph Bear Lake

Bear Lake is a popular tourist destination in Rocky Mountain NP, but when the sun is low in the sky or the stars are out you'll find the big crowd are gone. The lake is beautiful at sunrise and sunset but especially photogenic in the fall or at winter's end. While it doesn't have the darkest night skies it can still serve as an excellent location to watch meteors or photograph star trails abov...

Nymph Lake via Bear Lake Trailhead

While not as popular as Dream Lake, Nymph Lake is just as beautiful. The hike to Nymph Lake is an easy hike just over 1 mile. You start from the Bear Lake Trail head and can go further on to Dream Lake and Emerald Lake if you want to. Both Dream and Emerald Lakes are also stunning and very photogenic as well. Nymph Lake is a great spot to capture the reflection of the still water and beautiful ...

Ptarmigan Lake via Bear Lake Trailhead

The hike to Ptarmigan Lake has plenty of elevation gain for mountain lovers and views for miles from the Continental Divide. If you want to reach this spot for sunrise you'll need a very early start in the morning, but that also means you won't have to use the shuttle system to Bear Lake. The last half mile of the hike is off-trail so make sure to watch your step and practice Leave No Trace Pri...

Catch a Sunrise at Dream Lake

Begin at the Bear Lake Trailhead, located at the end of Bear Lake Road, 9 miles from the entrance on Highway 36. Follow the signs to Dream Lake, passing Nymph Lake about halfway through. At 1.1 miles you will reach Dream Lake. The views of 12,713-foot Hallett Peak and 12,324-foot Flattop Mountain from the east shore of this subalpine lake are incredible, and the perfect backdrop for this aptly ...

Hike from Bear Lake to Fern Lake Trailhead

On this Rocky Mountain hike you’ll explore 4 picturesque mountain lakes and a 60 foot waterfall. Completing this hike requires familiarizing yourself with Rocky Mountain National Park’s free shuttle system. Hikes along Bear Lake Road are some of the busiest in the park. Trailhead parking lots fill up early in the morning, so avoid the trouble and use the shuttles. To access Bear Lake trailhead...
