Doneraile Golf Club is located three miles from Cork, off the T11. It was founded in 1927 and is a pretty little nine-hole parkland course. It measures 6000 yards in length and has a par of 68, one more than the SSS. A river comes into play at a couple of the holes and, all in all, it's a very pleasant place spend some time swinging a golf club.
It's fairly inexpensive, too, and visitors are welcome at any time, though societies are encouraged to make prior arrangements. There's a practice ground, so make use of it before you head out on to the course. And, once you've finished, why don't you pop into the restaurant and bar.
