If Cobra is too much for you, get Mongoosed. Shorter climbers may find this harder than 5.8. Start at the bottom of the gully between Cobra and the Double Cracks block (exactly where Julie is standing in the 2nd edition guidebook photo, p. 105). Climb up a bit, using some holds on the Cobra face. Traverse left and pull over the roof (crux), then proceed to the top of the inside corner. An easier version (awkward 5.6) goes directly up the corner from the block above the tree.
BTW the next corner up the gully is short and guarded by loose rock at the bottom.
No fixed gear. Trees and gear for toprope anchor
