Fantastic place but be careful it's straight into the Atlantic. I haven't been since the new quay was built but the old one was approached with respect and only in good weather. I had a Valiant 520 by the way. Anchor routine should be practised, at your straight onto a rough lee shore in any type of west wind.
Inis Oírr is grand in anything but a south easterly, and has pubs 5 minutes from quay. Inis Meáin is grand but a hike to pub.
In Cill Ronáin I park across from ferries or go into Cill Éinne. Harbourmaster there now so watch your speed going in.
Liscannor is doable and worth doing, watch out for Kilstiffin at mouth of Bay, and a lovely natural sea arch on the way beneath Hag's Head.
Enjoy it, but I wouldn't risk anything over F4 with kids.
