Bear Lake is a popular area on the east side of the Continental Divide. From the Beaver Meadows
Entrance Station on U.S. Highway 36, head west about 0.2 miles and turn south on Bear Lake Road
(toward Moraine Park). Follow Bear Lake Road a little over 9 miles to the large parking area where Bear
Lake Road ends. Bear Lake is just west of the parking lot. The Emerald Lake trail begins southeast of the
lake; the Flattop Mountain trail begins on the east side of the lake.

The route to Hallett Peak begins along the Bear Lake lakeshore trail. Follow the Flattop Mountain Trail from
the east side of Bear Lake, and ascend Flattop Mountain on the 4.4 mile trail. From the summit of Flattop,
leave the maintained trail, and hike south toward Hallett Peak along the ridge above Tyndall Glacier. After a
level stretch, the route up Hallett becomes steep and rocky, with occasional cairns marking a route. This
route is a relatively brief scramble over boulders, leading to the small open area on Hallett Peak.
