Twelve days from Canterbury to the cliffs of the west of Ireland, following the saints who carried the faith across two islands.

The road runs from London and Windsor to the National Shrine of Our Lady at Walsingham, on through Salisbury, Glastonbury and Bath, then across the Irish Sea by ferry. In Ireland it turns south to Cork, west around the Ring of Kerry to the Cliffs of Moher, and north to Knock, where Our Lady appeared in 1879 — closing with three nights in Dublin and a free day before the flight home.
