Take the Portage Valley Road off the Seward Highway as if going to Whittier. A short 5 minute drive will bring you to a point where the road crosses a small creek. Immediately after the creek crossing take the right-hand turn. If snow levels are high it is common to find a small, plowed parking area. If low snow levels exist take the obvious dirt road back into the trees to the base of a large avalanche chute. The climbs are located to the west of the avalanche chute approximately 250 feet above a small creek. Hike to the base of the climbs.
