Hi, there's a pier in Ros, have a look at the map here...

Good chance of mackerel or pollack at high water I'd say.
Also, the road out to the pier also has a couple of obvious spots where there's easy fishing from the side of the road for bass, flats and maybe giltheads..fish an hour either side of low water to minimise weed.
Hope this helps...
