Glad to hear you had a good visit @david_cumner !
Some wires crossed a bt here - at Plas Tan Y Bwlch it was a walking weekend aimed at Welsh learners led by Catrin Roberts who talked about history of the places we were passing through and the wild life (if you saw the Cynefiin series on S4C, one of the people who was in the Blaenau Ffestioniog episode talking about the area and who's also a Welsh tutor).
The literature course for Welsh learners was at Nant Gwrtheyrn in May with Bethan Gwanas as tutor and focusing on extracts from a selection of books by some living Welsh authors, e.g. Lleucu Roberts, Ifor ap Glyn (who also came to talk to us), Sonia Edwards, Manon Steffan Ros (who was also going to come and talk to us but unfortunatel was ill at the tine, and so her editor substituted for her), Mihangel Morgan (I've a feeling I've forgotten one of the authors), the object of course being to get plenty of practice speaking Welsh with the extracts providing a discussion topic - Bethan G was a great tutor and there was a lot of hwyl, so highly recommended depending on where you are with your Welsh (the course was classified as Uwch). Hope this helps
