You can access the mark by walking down the slipway by the Eggy Ferry pub from @ 3 hours before low water,depending on the tide/wind direction....the water gets deeper the further you go towards the ferry terminal,which is better for the codling as they prefer the flow,but it also gets snaggier,so expect to lose a rig or two. The whole stretch can produce codling,though if you fish the near/cleaner ground,you will increase your chances of success with greater casting distance, Usual rigs/baits will work with the majority of fish in the 2lb to 4lb bracket...
If you are looking for a longer session,you can fish from the prom near the tunnel vents and follow the tide out as it ebbs...there is a series of steps down to the beach from the prom,but take care as they can be a bit weedy/slippy. Similar to Vale Park,the action is usually best early on.
