The peak lies within the San Francisco volcanic field, a landscape that Native American tribes of northern Arizona regard as sacred. The summit's fire lookout, staffed in summer, gives walkers a view over the lava flows and cinder cones of the surrounding field.

The hike is demanding and takes several hours to complete, so sturdy hiking boots and plenty of water are essential. The best time to visit is from spring through fall when weather conditions are most stable and enjoyable.

O'Leary Peak is one of the San Francisco volcanic field's landforms in Arizona, listed at 2,718.54 metres above sea level in the sources. The German text's claim of an "active-looking" cone is not supported: Sunset Crater is a separate volcanic cone nearby, and the sources give no eruption dates for either.
