Hike Flattop Mountain and Hallett Peak

Bear Lake Trailhead - Search Nearby - 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.

Summer, a season not to be missed in Aspen!

"I came for the winter, and stayed for the summer," is a phrase you'll often hear around town.  The weather is one of the highlights. During the day the temperature hovers in the 70's and 80's, and by evening the mercury will drop into the 60's. Arts & culture enthusiasts will be just as fulfilled as the adventure junkie during summer in Aspen.  The events calendar abounds with activities for everyone, from cultural events to athletic pursuits.

Experiencing all Aspen has to offer is as easy as opening the front door. Join us for a summer adventure that’s anything but ordinary.
