Hike Flattop Mountain and Hallett Peak

10.3 miles 3240 ft gain  - Out-and-Back Trail

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.

Fun Hike!

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.

Otis Addition

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.

Awesome views in every direction

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

Great hike with views all around

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.

It's a pretty strenuous hike, by its really beautiful especially when you get to the Boulder fields
