You step onto the Royal Mile before dawn, breath clouding in the chill, and a bus with blue‑vested guides idles at 60 High Street ready to pull you into the long, ragged spine of the Highlands. Over five days the road makes itself the story: coastal spray around Oban, the iron arches of Glenfinnan Viaduct curving through heathered slopes, the Cuillin silhouette on Skye rising like a folded fist. The itinerary moves at a Highland pace — windows framing stone castles, lochs that keep their own secrets, and a handful of short, satisfying walks to stretch stiff legs.
