trekking in county cork

Hi, I will be in Cork doing an English course during the month of January and I would like to explore the countryside by joining some trekking club / association, etc . Could anybody recommend me one where i don´t need to become a member ? I am a Spaniard and my English is pretty fluent.
Thank you so much

In the UK and probably also Ireland it's known as rambling, if you Google for it you should get a good deal of information

You can find a list of clubs on http://www.mountaineering.ie/
