+### Optional east coast extension (Cork → Dublin via coast)
+If you have an extra day or two, the route Cork → Dublin via the east coast is worth considering: **Waterford** (Viking city, crystal heritage), **Wexford** (medieval town, good beaches), and the **Wicklow Mountains** (Glendalough monastic valley, the "Garden of Ireland"). The east coast is gentler and greener than the west — a nice contrast after the Atlantic. Currently not in the itinerary as there's no room, but if you shave a day elsewhere this is the extension to add.

+## Day Trip Option: Newgrange, County Meath
+45 min north of Dublin. A passage tomb older than the pyramids (3,200 BC) and older than Stonehenge — the chamber is aligned so sunlight floods it at the exact moment of winter solstice. Not a must-visit, but if you have a free morning on Aug 29 it's an easy detour and genuinely impressive in scale.
