Sorry Craig, I was waiting for you to reply to John (TFC) before chipping in.
The map on the portal page is very good and has lots of reviews.
My stomping ground is mainly on the SouthWest coast in West Cork and Kerry. Some great campsites over this way. Roads not the greatest but worth the effort.
Heres a few ideas for you -
Campsites -
In Kerry I'd recommend the Flesk (Killarney), Wavecrest (Caherdaniel) & Mannix point (Cahersciveen). Be aware the roads in Kerry can be a bit challenging so only venture off the beaten track if you are a confident driver. Having said that, the N70 on the ring of Kerry is fine as long as you follow the coaches who take an anti-clockwise path on that route.
In Cork, I'd recommend Eagle Point (Bantry) or Sextons (Timoleague).
In the sunny South East our favourite site is Morriscastle strand in Kilmuckridge but it can be very busy there. There's a beautiful beach which keeps drawing us back.
Unfortunately we haven't yet wild camped so I can't advise you there but I can recommend you review our POI's for those.
Scenic drives -
The Burren, Ring of kerry & The gold coast road (in Waterford) should not be missed.
Beaches...
Plenty of beautiful beaches on the West coast and further south. Lehinch, BallyHeigue, Ventry, Caherdaniel, Barleycove, Inch Beach, Youghal, Tramore... My favourite of that lot is in Caherdaniel. Breathtaking beauty.
Mizen Head...
Not a great road but again, great view, good destination and a great beach nearby in Barleycove. Head for Crookhaven for some nice pub grub in the Crookhaven inn. A regular destination of mine when on out for spins on the motorbikes.
