This should be a simple park and grab but as your in the area why not continue on down to Fountainstown beach.
There's lots to do whether the sun is shining or not. Try to brave the cold Irish waters from the beach, jump in off of the rocks, go for a stroll along the coast road or enoy an ice cream while watching the waves! 
You can find space to pull in at the posted coordinates or you could drive down to the beach and walk back to GZ. Theres usually parking at the beach but it can be very busy at times.
