Achill and Westport Recommendations?

Hi there,

I'm camping for three nights at the end of August for 6 nights - 3 nights in Westport House and 3 nights in Dugort/Doogort, Achill Island.

Dugort looks a nice sandy spot, hoping to have a go there.

I was wondering has anybody any recommendations close to either area of where to fish and what species to expect?
Is there anywhere to buy bait close by too?

Thanks in advance guys,
Colin
