Railbookers · Independent rail package
Twelve-night rail trip through Paris, London, Edinburgh, and Dublin
Railbookers offers this 13-day, 12-night independent rail package that links the capitals of France, England, Scotland, and Ireland by train. The trip begins in Paris, then moves to London for the Tower of London and Westminster, before heading north to Loch Ness, the Highlands, and Edinburgh Castle. From Edinburgh, the description says travelers take the trains through the countryside to Dublin for three nights, closing the trip with Dublin's culture and history and a local food tour built around traditional Irish cuisine. Railbookers does not publish a day-by-day itinerary, and beyond the three confirmed nights in Dublin, how the remaining nine nights split between Paris, London, and Edinburgh is not stated. As an independent rail package rather than an escorted tour, travelers plan their own sightseeing at each stop. This suits travelers who want to cover four capital cities and Scotland's Highlands scenery in one self-guided rail trip.
