Hike into the main area of the Lower Satellites by following the signs to the Third Flatiron. Fifty yards after walking between the A-7 and BBC Boulders, look up to your right off the trail for a large boulder. Behind this boulder to the northwest are two 10 foot high boulders standing side-by-side.
Docking Port ascends the southeast corner of the left boulder. Match on a good head-high edge, get your feet on and reach for a good edge. The hard part's over, so just climb up and over.
