Elevation: 5,150 feet. A much-less-traveled and longer alternative directly across the valley from Flattop. It takes the average hiker 2.5 hours to summit and 1.5 hours to descend. If you've already hiked Flattop and want something different, O'Malley is your next best choice.
From the parking lot walk down either of the two trails between the caretaker's cabin and Flattop's introductory steps. The trails merge at the Powerline trail. Take a right. Take your first left off of the Powerline trail. Hike down, cross bridge, walk on boardwalk and then take a quick right on a narrow sometimes muddy trail. Shortly after taking this right, the trail curves and takes you where you wanted to go when looking up from below. When you summit the first ridgeline, take a right. Keep going.
As you can see from the pictures below, awesome views await. Monitor the clock and stick to the turnaround time so you get back to the shuttle on time. If you don't want to worry about time, the Hike/Bike Combo allows you to do both at your own pace.

Looking north from O'Malley Peak this photo shows Flattop's southern profile and its elevation gain. Stand on the flat rocks in the foreground for a thrilling view. This is the point most hikers who choose O'Malley will have to turn around in order to make it back to the van by 4pm.
