An hour or so outside of Cork. The biggest town which is right next to it is called Rosscarbery. Ownahincha turning is on the top of the hill going into Rosscarbery from Cork. Easy to spot
I would say Ownahincha is separated into 2 beaches due to a rock formation and an extenstion of the dunes which the Life gaurd hut is ontop of. Both are fun but i think the easterly beach has a wider swell window and is a tad steeper which can improve the set up. Try fishing off the rocks and catching some bass :D Chat to the friendly locals and lifegaurds. There is a little car park behind the dunes which is handy as it leads to both beaches. Oh there are loads of jellyfish but they dont sting and i often surfed with seals!
Overview
Atmosphere
All the local people are sound. I stayed right on the beach front for two weeks in Summer of 2004 but typically the surf was poor as it was a rare high pressure (for ireland) system overhead. The surf only picked up to a foot or two on a couple of occasions but it was real fun and you could see the potential. If there is no surf there go over to Long Strand over the point (eastwards). Can't wait to go back again.
General
Love it. Real pretty and cool area. Got small waves but saw the potential.....Want to go back.
