Leave Dingle town after your evening meal, not before it. The road ascends westward past Ventry, constricting above the sheer drops at Dunmore Head. Then it expands into the vista that captivates you. The Blasket Islands rest offshore like a small armada, the Atlantic shifting from silver to pewter to a muted rose, dictated by the cloud cover.
This is the event you seek. Go between the middle of June and early July, starting from Dingle at 8:30 PM with a warm layer. Make dinner reservations in town for ten, not eight. Go for the light.
