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.

Pack List

Normal Day hike gear
An Ice Axe if the trail is snowy or if you plan to descend into Chaos Canyon
Foot traction device if snow is present

Hike Flattop Mountain and Hallett Peak

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.

Hike Flattop Mountain and Hallett Peak

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.

I am from the Pacific Northwest, where the mountains meet the sea. When I eschew the trappings of the modern world and venture into the mountains I feel as though I am revived by simplicity, renewed by the power of violent geography.
