Wakina Gulch is closed to public access according to signs at the start so no access is available from that side.
Start at the intersection of Wakina Sky Trail and Barking Dog Trail. Head up through the trees. From there the trail will climb, but not steeply, before leveling off and hitting a couple of rocky sections, all very hikeable, though. The trail will then drop and hit some short switchbacks taking you down to Wakina Gulch.
