Although it is backtracking 28 minutes to Mulranny, a perfect pair of 9 holers is Mulranny(not to be missed), followed by Connemara Isles(not near Connemara), a fun 9 holer on the water exactly on the way as the crow flies.
Plenty of enchanting, interesting scenery along the way as mentioned.
4 1/2 hours of total driving from Westport back to Mulranny, down to CI, down to Lahinch.
Both courses and the(detoured) drive highly recommended.
