Triona gave us a very informative tour including a short walk down to bay where all the action takes place (under water). Didn’t matter what we asked . . Triona was able to answer. Then back to the factory for the shucking demonstration and tasting (3 absolutely fresh, large oysters per person) where we were further entertained by the owner David. Well signposted from Letterfrack – easy to find by Google Maps in any case. We strongly recommend.
