I dont know of one in clonee but for excellent facilities, Id suggest ratoath harps just up the road, or try either verona or st mochtas behind blanchardstown SC. All 5 mins away and they have astro for training.
Another one not far from Clonee is Dunboyne FC, they have two Senior sides in the LSL. Pitches are the opposite side of the Village from Clonee but they have a good set up.
