Hi Willem,
Thank you for joining our Community, and it's great that you are bringing your instrument with you! Your itinerary seems already well thought of.
From experience, many
pubs have weekly (or sometimes nightly)
traditional sessions or jam sessions that welcome guest musicians. I'd encourage you to reach out in advance to pubs and ask if that's an option. Don’t forget to ask locals at each of your stop—they often know the best spontaneous jam spots! I have seen musicians join at the Crane or Taaffes in Galway for instance, and apparently, pubs likes
D O'Shea's in Sneem or
McCafferty's in Dungloe have sessions.
We also have previous threads from musicians who traveled to the island with useful tips
here and
here.
Let us know how your search goes and happy planning!
Antoine
