Killybegs has to have the best slipway I've ever seen.
I can't see me doing this one but it's a fantastic plan. I've long intended to do a tour of the western islands - inside the general area from the Cliffs of Moher in the south, encompassing the Aran Islands, Inishbofin and Inisturk, Clare Island and possibly up into the myriad of islets and torrs to the north around Belmullet. You could kill a week in there and not see it all. The craic on the inhabited islands is fierce during the summer. I really think that it's a weather call - it's a very exposed coast...
Someday I'll do it.
