Park at the Cannon Cliff lot (first exit after tram going south) then walk the bike path north towards Echo Lake passing under the highway, quickly coming to a wooden bridge. Break right into the woods before the bridge following a deer trail along the ridge parallel to the drainage. Trend slightly right past three cairns until you come to the mouth where the drainage narrows and steepens. Continue up for 5-8 minutes looking left for a obvious climber trail that breaks off when the stream bed turns into wet muddy slab just past a large down tree. Follow the climbers trail as it breaks left taking you to a steep rocky gully (be careful of loose rock) which deposits you at a plateau in the woods just down and left of the trickling waterfall that is Ace of Spades. From here either continue to scramble up two steep steps above the gully to reach the Gonzo Wall or traverse directly right across the top of the slabs to reach the Joker Crag, with Wumbo wall another 200ft along the trail. For your first time expect a 20-30 minute approach to reach any of the crags. Once you know where you are going it is about 15 minutes of moving uphill.
