A friend of ours has been to the Boghill Centre quite a few times now. He plays fiddle and had a fantastic time. His playing certainly improved after a week there. He said the food and the atmosphere was great, quite intense learning I think but they also got out and about for sessions. I should imagine that if you are travelling on your own and are also keen to improve your instrument without getting too ensconsed in the pub culture then it would be a lovely week with good companionship. Nice part of the country too!
