Alnwick Castle: the Harry Potter castle and how to visit it from Edinburgh

A Percy fortress on the Scottish border

Alnwick Castle guards a crossing of the River Aln. Ivo de Vesci built the first parts around 1096 after the Norman Conquest, and King David I of Scotland captured it in 1136. William the Lion besieged it twice in the 1170s and was captured outside the walls at the Battle of Alnwick. The Percys bought the castle in 1309 and rebuilt it in stone as a major border fortress. The Abbot's Tower, the Middle Gateway and the Constable's Tower survive from that 14th century building programme.

In the 18th century Robert Adam, Capability Brown and others remodelled the castle for the returning Percy family, and between 1854 and 1865 Anthony Salvin was paid £250,000 to re-medievalise much of Adam's work. That layered interior is what you walk through today. It is a Grade I listed building and still the home of the 12th Duke of Northumberland.

• Built from about 1096, rebuilt in stone by 1157
• Percy family home since 1309
• Salvin's 19th century remodelling created today's look

The Harry Potter castle

Alnwick Castle is famous worldwide as the castle used for exterior shots of Hogwarts in Harry Potter and the Philosopher's Stone and Chamber of Secrets. The courtyards and outer walls doubled for the school's grounds, and the flying lesson and broomstick training scenes were filmed here. In season the castle runs broomstick training sessions on the very spot, which is why families plan whole trips around it.

Filming is only part of the draw. The castle has appeared in other productions including Downton Abbey, and in 2016 it drew more than 600,000 visitors a year together with the adjacent Alnwick Garden. If the film connection is your reason for coming, the Harry Potter themed day is built around it, and you can compare it with other castles in England.

Gatehouse, courtyards and the film spots

You enter through the gatehouse into the outer courtyard, where most Harry Potter filming happened. The two courtyards are open ground you can walk at will, and this is where broomstick training sessions run in season. Give the courtyards the first half hour of your visit because coach parties fill them later.

From the courtyards you can walk the walls and battlements for views over the park and the town of Alnwick. The State Rooms, richly remodelled in the 19th century, are the family's grand interiors, and the Great Kitchen is one of the castle's most talked about historic spaces. Check the day's programme on arrival, because exhibitions and activities change through the season.

• Outer and inner courtyards, the Hogwarts filming spots
• Broomstick training on the filming location in season
• State Rooms and Great Kitchen inside the keep
• Walls and battlements with park and town views

The Alnwick Garden next door

The Alnwick Garden sits adjacent to the castle and is a separate attraction with its own ticket. Its best-known features are the Poison Garden and the Grand Cascade. The two sites together received over 600,000 visitors in 2016, so the Garden is not a quiet add-on in high season.

If your tour gives you more time on site than the castle itself needs, the Garden is an easy second stop on foot. If your time is short, stay with the castle: the interiors and film locations are what you came for, and the Garden deserves a proper visit of its own.

A short season, no winter visits

The castle closes completely for the winter. The castle closes for the winter and the castle reopens in March. This matters twice over. First, you cannot plan a winter visit at any price. Second, all the Edinburgh day tours run their Alnwick stops only inside the season, so check dates before you book flights.

Hours within the season are published on the castle's own website, so check there before travel rather than guessing. Online tickets are sold as 12-month season passes at $29.40 (£22) for adults, which means a return visit in the same season costs nothing extra.

• Reopens March
• Adult online ticket $29.40 (£22), valid 12 months
• Concession $23.90 (£17.90), child 5 to 16 $15.51 (£11.60)

Quiet times and booking rhythm

The castle draws coach crowds mid-morning through early afternoon, so the first hour after opening is the calmest window, our estimate. UK school holidays are the busiest stretch, especially for broomstick sessions which fill fast.

For tour travellers the timing is fixed by the operator, not by you. The 08:15 Harry Potter departure reaches the castle early in the day, which is one reason we rate it. Every tour here offers free cancellation up to 24 hours before the start, so book early and adjust later.

From Edinburgh, the practical route

Alnwick lies south of the border on the coastal side of Northumberland, roughly an hour and a half's drive from Edinburgh by coach. The tours leave from two meeting points. Timberbush departs from Castle Terrace, the Harry Potter small-coach day from 60 High Street on the Royal Mile at 08:15. Arrive at least 15 minutes before your stated departure, and note that the Viator Holy Island and Alnwick coach has no restroom on board.

Driving yourself is possible but rarely worth it for a day trip, because the tide-dependent Holy Island crossing and Bamburgh coastal stops are what make these days special, and a driver-guide handles both. If you are building a wider border itinerary, see our castle day trips and the other castles in Scotland within reach of the same city.

• Castle Terrace departures: the Holy Island and Alnwick day and the Viator Northumbria coach
• Royal Mile departure 08:15: the Harry Potter themed day
• Arrive 15 minutes early at any meeting point

Three ways to split the day

A tour stop gives you roughly two to three hours at the castle, enough for the courtyards, the walls and either the State Rooms or the Garden, not both. The table below shows how our three routings trade castle time against the rest of Northumberland.

If you want more depth, the castle's 12-month season pass makes a second self-drive visit cheap. If you want more breadth, the Holy Island routings add a tidal crossing that no flexible schedule can guarantee. Decide which matters more before you book, because the two day shapes are genuinely different trips.

• Book the earliest departure for the quietest castle hour
• Keep one flexible hour for the State Rooms
• Season pass covers a return trip within 12 months

Read these before you go

Most people arrive knowing only the Hogwarts connection. These five points from the historical record add depth to a two-hour stop.
