Bait fish off St Mary's Island. Get on before the causeway becomes submerged. Dont wade on if it is submerged as you can get quite a strong tidal current running over it. As the tide floods fish from the Northern side of the island into Crisps Gulley and straight out North towards Blythe Pier. As the tide ebbs move round to the east of the island, stand on the rocks to the south of the concrete pillar, casting parallel to the gulley.
