The Wall of the Waltzing Witches faces in a sort of southerly direction, on the other side of the ridge south of Munchkin Wall. Where you head right down off the ridge right at the end of the approach to get to Munchkin Wall, you turn left and head up and over to get to this wall. The routes are easier by and large, and more slab style than Munchkin. The sun hits this wall from early day to afternoon and can be hot in the summer, so plan accordingly.
From the general area description: Drive to the end of the Rose Canyon road and park in one of the large lots, there is also some parking along the road if it is crowded. I think as long as you park by a blue dumpster, you are ok. From the slabs behind the (defunct) snack bar and picnic ramada, pick up a trail(about the top and middle of the slabs, maybe a little on the left side) heading north/east(the trail will go mostly east and curve south slightly) and take it to the ridgeline(crossing several fallen trees), then follow it to a clearing/slab. For the Towers, Wall of Marching Munchkins, and Wall of Dancing Dwarves, turn right and follow a short section of well-groomed switchbacks downhill to the climbs. For the Wall of Waltzing Witches, turn left at the clearing. All trails should be well-maintained and marked with cairns. Another way to access the Wall of the Waltzing Witches is to head up the gulley between the Two main walls and go straight across the slab at the top and turn right to hike down to the wall. This is probably about a fun 5.3 free solo.
