200m north of bridge to south stack is a prominent sea arch, with a slabby side. It is only just visible from south stack island. The routes are approached by abseiling from blocks down the outside of the arch, a sea level traverse of 40 metres leads to the routes, which are described left to right. This area can also be approached easily from the Trinity House Walls abseil followed by a sea level traverse in to the zawn. This traverse is not affected by the tide until one reaches The Flying Shed, which cannot be crossed at high tide.

The Man from Uncle HVS 5a 25m *
This takes the front face of the thin buttress to the left of the cave below Thunderbird and opposite the arch. Climb the rippled buttress by two cracks running up the face and trend around steeply left where the cracks lead. Finish back right and follow the ridge to the top.

An exciting trip up the hanging corner left of The Flying Shed, joining this route at the apex of the zawn.
Description: climb the wall left of The Flying Shed close to the arete of the zawn and directly under the hanging corner. Follow the corner to some jammed blocks, where moves right over the apex of the zawn reach The Flying Shed. Finish up this into the grass above.

A kind of counter-diagonal to Crack Eats Man Alive! with all the difficulties concentrated in the first 5m. Extremely marvellous and climbs the most beautiful rock. Start beneath a downward pointing whale’s fin on the right side of the cave.
1. 5m 6a. Gain the fin and shuffle awkwardly out and pull round into a crack. Climb the stiff crack until one can step left to a spike belay..
2. 10m. 5c. Move left onto a good hold then go left again onto the undercut wall. Climb up the arete for 5m then go right and down and around and up onto a ledge and belay as for Thunderbird.
3. 15m. 5c. Move left and go up into a groove. initially awkward moves gains the corner proper, followed by lots of scrambling to the top.

Start on the long quartz ledge, at the left hand end of the slab, under the overhangs.
1 14m 6a. Climb the obvious groove and step across the void onto a wall. Move left, peg, under the roofs, then step down around the arete. Move across to the base of a short groove. Up this, moving left to a block belay.
2 23m 5c. Climb rightwards along a quartz gangway, under a roof (peg) and move round into a groove. Follow this to a small roof, step right onto the overlap and finish up an arete.
Dave Jones and Ray Kay (AL), 15/9/87.
1 20m. 6a. Climb the wall to the obvious notch on the arête.
2 20m 6b. Traverse 20 metres left, just above the lip of the arch, passing various pegs (mostly rust free Titian) to a hanging stance on the left hand side, at a good crack and peg.
315m. 6b. Move up and lunge right to another peg. Climb up passing two more pegs to an exciting finish.
The next 2 routes lie on the front slab of the sea arch.
Fab VS 4b 30m
The left hand line of the slab. Follow a right slanting crack in good rock then climb directly to the top on gradually deteriorating ground.
A. Wainwright and J. Bonnet, 02/06/07.
