Hidden off-route spots: The town of Saffron Walden (between Cambridge and Ipswich) has a maze and ancient church. Also, the village of Orford has a castle and excellent seafood.

Infrastructure note: The A55 in North Wales has average speed cameras; the M6 Toll is speed-camera free. In Suffolk, the A14 is dual carriageway with frequent roundabouts.

Leaving Sligo, the landscape features the Dartry Mountains and Lough Gill. Stop at Benbulben, a distinctive table-top mountain, for a short hike. The N4 then passes through the drumlin country of Leitrim and Cavan.

In Dublin, the route is urban, but the ferry offers views of Dublin Bay and the Irish Sea. Arriving in Holyhead, the A55 skirts the Snowdonia National Park. Detour to Conwy Castle (UNESCO World Heritage Site) or the Great Orme in Llandudno.

Further south, the Midlands offer flat farmlands, but hidden spots include the aviation history at the Imperial War Museum Duxford (near Cambridge) or the medieval wool churches of Long Melford.

Local commerce stops: Sligo markets (Saturday), Holyhead's fish stalls, and farmers' markets in Bury St Edmunds (Wednesdays and Saturdays).

UNESCO World Heritage Sites within reach: Brú na Bóinne (Newgrange) near Drogheda, just off the N4; the Castles and Town Walls of King Edward in Conwy; and the Jurassic Coast is too far, but the city of Bath (via a detour) is 3 hours from Ipswich.
