we went down about 3 weeks ago and you could still get into the carpark as johnf says it throws up some corkers during the summer
the only downside is the smell and the flies,aye and watch out for the rats lol if your night fishing if you leave your bait out they will have it away first chance they get best to keep your box closed,never had any bother with the 2 legged ones and the cars in plain sight so you can keep an eye on it
the fish quay is also a good spot we fish behind the pub beside the flats casting slightly upriver onto clean ground,weve had flatties to about 1lb from there with plenty smaller ones
