Expect strong sun, wind, cool temperatures, and rapidly changing weather conditions. Carry layers, sun protection, and ample water. Get a very early start to avoid afternoon thunderstorms. Use caution when crossing snow near ledges and cornices.

The climb from Flattop to Hallett Peak offers spectacular views and a rare chance to explore the open tundra with "relative" ease. From the summit area of Flattop, head south skirting above the huge cirque that holds Tyndall Glacier. Give this formation room and the respect it deserves. Look for a faint trail marked by cairns, although it is often hard to pick out the cairns from the steep talus landscape. If you've lost the trail, just continue south, eventually bending southeast towards the summit. Take heart, it is easier to find the established path when looking down on it from the summit.

At the summit, you'll be greeted by several wind shelters. A topo map will help identify neighboring Otis Peak (12,486'), Taylor Peak (13,153'), Longs Peak (14,259'), Notchtop Mountain (12,129'), Ptarmigan Point (12,363'), and portions of the Mummy Range, Never Summer Range and Grand Lake area. Turn northeast for good views of Tyndall Glacier and gorge, and southeast for Chaos Canyon and Lake Haiyaha.
