From the Fireworks Boulder in the First Boulders, follow the trail, on the left side of the boulder, straight up the hill. You will pass a boulder, the Ledges Boulder, way out left, with briars protecting the direct approach, as you hike up the hill...keep hiking up the trail and avoid the briars. Eventually the trail bears left and hits the first boulder, the Lung Buster Boulder, in this set. If you stay on the trail past Lung Buster, you'll hit the Steal Your Face Boulder followed by the Dark Corner Boulder down the hill. The last boulder below Dark Corner is the Ledges Boulder, seen from the approach on the bouldering trail on the way up the hill from the Fireworks Boulder and the main boulder seen uphill when hiking between the Unclimbed and First Boulders on the Shut In/Mountain To Sea Trail. An alternate approach and much easier to hit the Ledges Boulder, is to take a discrete trail left off of the Shut In/MST just before you see the Ledges Boulder uphill on the way to the First Boulders.
