Welcome to our Community!
It's so nice to hear that you'd like to learn the Gaelic language and spend some time in Ireland! 😊
One of the best sites where to look for information about courses and stays is for sure the Foras Na Gaeilge page. At the bottom of the page, there are many links to organizations that promote the Irish language and provide language courses:
they provide language courses in Galway
they offer online classes, courses in Dublin, Galway and other locations. Check this page
to know more.
: they offer courses in the Gaeltach areas, those where the Irish language is commonly spoken.
Also, I invite you to check this thread of the Community,
dedicated to the study of the Gaelic language.
I hope this information helps you!
Ti auguro una buona giornata e ricorda che puoi anche scriverci in italiano se lo preferisci!
