Hi Valley Girl,
I don’t know of a class run in Porth who is the teacher?
However most classes wherever you go are run on a drop in basis therefore you don’t need to book a place, it’s just a case of turn up on the night. On the other hand occasionally some classes may be course based ie run over specific period of five or six weeks. It’s probably best you contact the teacher directly in advance just to check.
Lisa runs a class in Abercynon on Mondays details can be found here. http://nat.heminc.co.uk/salsa/.
It’s also worth occasionally popping down to Cardiff if you can make it. Details of the classes in Cardiff can be found on the front page of this website.
Good luck!
