Hike Flattop Mountain and Hallett Peak
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.

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.
