We decided to book the short flight to Inis Mor, and we had great weather that day, so all went well. We booked an early flight, I believe around 8:30am. It was pretty neat to take the very short flight, and upon landing we took a shuttle to Kilronan and rented bikes. We were actually the only people at Dun Aengus, so that was a real advantage to getting there so early. Having booked a late afternoon return flight, we even had time to bike (and then hike) out to the Worm Hole, and visit the Seven Churches site. And we still had time to look around in some of the small shops afterwards! Overall, I thought flying was the best way to maximize our one day on the island. The extra $$ was worth it in our case (2 travelers). In our case, no downsides to flying, and we were lucky to have such nice weather.

My husband and I are planning to make a day trip to Inis Mor in late June (not staying overnight). I have read several previous threads about the advantages and disadvantages of flying vs ferry. We would be staying in Galway and using the ferry from Rossaveal. It’s my understanding that either could be cancelled due to weather conditions. Has anyone experienced traveling to the island in the morning and then some type of weather event preventing your return to Rossavel? Basically, is it possible to be “stranded” on Inis Mor as a daytripper? What would the backup plan be, or is this something that really never happens? Hard to believe it would be easy to find a last minute room during the busy season.
If choosing the ferry, does it often “sell out”? Can tickets be had a couple of days out based on weather, or is that taking a risk of none being available?
Also wondering if the airplane is a better bet for weather than the ferry? As in, is it generally more likely for the ferry to be cancelled or the flight.
Thanks in advance for any expertise!
