Hike the Cooks Wall trail to House Rock. From House Rock walk uphill for 10 minutes to the Cooks summit. Walk another 5 minutes, across the ridge over flat rolling terrain, until you come to Devil's Chimney, which is the very obvious gully/cleft on your left. In order to get to the base with packs, continue to walk the main trail going west and turn left into the woods just past the gully. Make your way through the woods on faint trails that eventually lead you over and past several boulders and to the bottom of the cliff. You will have come in on the west side of Devil's Chimney; walk across the narrow corridor to the east wall, which will be climbers right. 'Hanging With Diablo' will be the farthest left line into the throat of the chimney.
