Hi Ian!
It's great to hear you're thinking of travelling along the
Wild Atlantic Way this year!
There are a number of great articles on the Ireland.com website, including this one on
campervan holidays (which includes some useful travel tips as well as campsite locations), and this one on
camping in Ireland.
You can also search for campsite locations on the
Camping Ireland website. I've already applied filters for campervan and caravan parks that are located along the Wild Atlantic Way, but feel free to modify this to suit your needs. You'll be able to get an idea of the sort of parks these are in terms of size and capacity.
If you're looking for some ideas for your itinerary, check out these
charming towns and villages along the Wild Atlantic Way that are definitely worth a visit, or this
Ring of Kerry road trip idea.
Let me know if you have any more questions!
Alex
