pm kieran he will bombard you with about a 100 "god" shore marks up there
down at the pier in the town itself its rough bottom - have heard some lads swear by it and others totally rubbish it, never fished it though
have only ever fished out of westport itself - achill, corraun, belmullet, mullraney - all a bit out of your way
you could always head down to murrisk - 4-5 km out the road near croagh patrick - theres a few beaches nearby and a couple of sandspits with any amount of stories about bass knocking round the back of them - theres big mullet there anway
good luck
