It begins, as the best adventures do, with a letter. One envelope, one impossible invitation, and an ordinary life tips sideways into a world of moving staircases, whispering portraits and trains that leave from platforms no timetable will admit to. On December 25, 2026, that world is conjured anew as HBO’s series retelling of Harry Potter and the Philosopher’s Stone arrives on screens. But here is the secret the films never quite let slip: the magic was real all along. It was borrowed from actual castles, cathedrals, railway lines and rain-slicked streets scattered the length of Britain, and every one of them is still there, waiting to be found.
Think of what follows as a treasure map rather than a guidebook. Trace the clues north to south and you can walk the whole story yourself, from the misty city where it was first imagined to the cloisters where its corridors were filmed. Threading so many stops together is its own quiet wizardry, and Pegasus makes it painless; for the mechanics, Flight Hacks: How to Plan a Multi-Stop Trip with Pegasus shows how to turn a single ticket into a whole quest. Wands optional. Rain jacket essential.
Edinburgh: Where the Spell Was First Cast
Every enchantment has an origin, and this one was conjured in Edinburgh, scribbled into notebooks in warm cafes and cold-water flats while the haar rolled in off the castle rock. The city practically hums with it. Victoria Street spills downhill in a crooked ribbon of jewel-colored shopfronts, so like a certain hidden shopping lane that you half expect a window of broomsticks between the booksellers. In Greyfriars Kirkyard, where the fog pools between leaning headstones, a slow wander turns up names that will stop any reader cold. And rising just beyond the churchyard wall, all turrets and spires, George Heriot’s School looks every inch a castle that sorts its pupils into houses. Come at dusk, when the closes darken and the lamps stutter to life, and the veil between this world and the other feels very thin indeed. The Edinburgh travel guide handles the earthbound details, airport trams, where to bed down, and when the rain relents. For the full four rainy days across Edinburgh and Dublin, we have charted a companion journey. Fly in on cheap flights to Edinburgh and let the trail begin.
The Scottish Highlands: All Aboard the Hogwarts Express
Now the story pulls you north, the way it always does, aboard a scarlet train bound for somewhere wilder. Beyond Fort William the Glenfinnan Viaduct sweeps in a great stone arc high above Loch Shiel, and this is no trick of the screen: the Jacobite steam train still thunders across it daily in season, trailing a white banner of steam exactly as the school express does in the films. Stand on the hillside as it rounds the curve, its whistle echoing off the braes, and the years simply fall away. All around lies the country that supplied the rest of the spell, the brooding pass of Glencoe, the black mirror of the loch standing in for the water below the castle walls, and mile upon silent mile of Highland that needs no special effects at all. No stretch of the journey feels more like stepping through the page.
South again, to a city that has always kept its magic tucked just out of sight. At King’s Cross a luggage trolley melts clean through the wall at Platform 9¾, where a shop and a waiting photographer let you take the leap yourself. Slip a few streets over and the gilded Victorian arcade of Leadenhall Market becomes the shadowed lane to a certain hidden inn, while the sleek Millennium Bridge is the very span that buckles so memorably on film. The initiated go hunting for Australia House on the Strand, whose marble hall of chandeliers doubled as a goblin-run bank, and every seeker saves a full day for the greatest vault of all: the Warner Bros. Studio Tour London, out at Leavesden, where the real sets and props stand waiting, from the Great Hall to the cobbles of Diagon Alley to the shadowed edge of the Forbidden Forest. Book that one far ahead. Arrive on cheap flights to London and the whole south of the story unlocks by train, and when you are ready to swap British drizzle for Anatolian sun, From London Skies to Turkish Sun: Cities You Can Fly to Direct with Pegasus maps the direct routes onward.
Alnwick and Durham: The Castle Made Real
To find the castle itself, follow the trail into the northeast of England. Alnwick Castle in Northumberland, vast and battlemented, lent its walls and its wide green courtyard to the very first flying lesson, and in season it still hands visitors a broomstick and coaxes them off the ground. An hour south, Durham Cathedral, one of the mightiest Norman churches in Europe, opened its cloisters and chapter house to stand in for the corridors and classrooms where snow once drifted past the windows. Even stripped of every enchantment, both are places that raise the hair on your arms.
Oxford: Halls of Learning and Moving Stairs
Oxford lent the tale its scholarship and its splendor. The great dining hall was modeled on, and its candlelit staircase filmed within, Christ Church College, whose real hall and fan-vaulted steps you will know in a heartbeat. Inside the Bodleian, the medieval Divinity School became the infirmary where the injured mend, and Duke Humfrey’s Library became the hushed shelves where the most dangerous books are chained behind a rope. In the cloisters of New College stands the gnarled oak where a certain unlucky boy was turned, briefly and memorably, into a ferret. Access shifts with the university term, so check the hours before you conjure a visit.
A West Country Finale: Gloucester and Lacock
The trail ends softly, in the green hush of the west. The fan-vaulted cloisters of Gloucester Cathedral are among the most-filmed passages of the early films, corridors of pale stone you will recognize before you have taken three steps. Twenty miles on, the honey-colored village of Lacock guards the last of the secrets: Lacock Abbey, whose medieval rooms became classrooms and the chamber where a certain mirror once showed a boy his heart’s desire, and lanes so untouched they doubled for the oldest corners of the wizarding world. It is a gentle, spellbound place to close the book.
Getting There with Pegasus
The whole quest links up by rail once you land, and Pegasus flies to its two best gateways through Istanbul Sabiha Gökçen, Edinburgh for the north and London for everything south, with cheap flights to Manchester a handy third for the castles of the northeast. Compare your options on the Pegasus route map. A journey like this gathers treasure as it goes, wands and scarves, a boxed set, a jar of something from the studio tour, so an upgrade package gives you the room and the flexibility to carry it all home. And since the adventure runs through Istanbul, do not rush the transfer: a stopover on cheap flight tickets to Türkiye can slip one more enchanted city into the tale before the credits roll on Christmas morning.
