Tafwyl is the main Welsh language festival in Caerdydd and will be taking place this year on 12-14 July in Bute Park.
It’s a fabulous occasion to get along to with lots of Welsh bands and cultural activities. Here’s the link to the main website to read more:

They’re looking for volunteers to help run the event and Welsh learners are welcome. I volunteered a couple of times myself in the early days of Tafwyl and it was a great opportunity to use my Welsh and generally be immersed in a Welsh language atmosphere.
