Beginning at O'Leary / Castle Rock Trailhead, O'Leary Mountain Trail #3321 heads east, switching back steeply up a large ridge through an old growth conifer forest. The trail continues uphill, following Forest Road 3321 until it passes below a panaroramic viewpoint on Macduff Mountain. Passing the mountain, the trail drops into a saddle, then sidehills east below McLennan Mountain. The trail occassionally breaks out of forest into rock outcroppings, then hooks north to reach its terminus at Olallie Trail #3529.
