Not a hypothetical guide — these are the actual trips we took, with the actual restaurants that were safe, the actual trains we caught, and nothing left as an open question.
Glasgow to Fort William to the Isle of Skye to Inverness to Edinburgh, entirely by train, ferry, and bus — with a celiac-safe restaurant pick for every stop.
City StopArthur's Seat, Edinburgh Castle, and three of the best celiac-safe dinners of the whole trip — including a 10-course tasting menu at LYLA.
