We stayed at a nice aires during the heatwave recently. It’s just a 10 min drive from Killarney town out the Dingle road.
It's on the grounds of the Doughlasha Bed/Breakfast V93 RX64 in Fossa. You can book a full Irish breakfast for the next morning too.
Ideal for an overnight or two.
EHU, Fresh water, grey and black facilities on-site.
