2 Days in Alnwick: The Perfect Northumberland Itinerary (2026)

Two days in Alnwick gives you one of the best short breaks in northern England. The castle that doubled as Hogwarts in the Harry Potter films, the contemporary Alnwick Garden with its extraordinary Poison Garden, and Barter Books — one of the great secondhand bookshops of the world — are all in the town. Add Bamburgh Castle and Holy Island within 25 miles and you have a destination with depth far beyond its population of 8,000.

Day 1: Alnwick Castle, the Garden, and Barter Books

Morning: Start at Alnwick Castle. Founded in 1096, it is one of the largest inhabited castles in England and the seat of the Percy family, Dukes of Northumberland. The State Rooms are lavishly furnished with Italian paintings and period furniture; the grounds include the Hulne Abbey ruins visible from the outer walls. Entry: adults £18.50, children £11. Allow 2 to 2.5 hours. Note: this is where the flying lesson scenes in Harry Potter and the Philosopher’s Stone (2001) and Chamber of Secrets (2002) were filmed.

Lunch: The Treehouse Restaurant in the Alnwick Garden is the most unusual lunch in Northumberland — a high-level wooden restaurant built into and around trees on the edge of the garden, with rope bridges, open fires, and a menu of seasonal British food. Book in advance; it fills quickly. Mains £16-£26.

Afternoon: Enter the Alnwick Garden (adults £16, children £9.50). The contemporary garden opened in 2001 and designed by Wirtz International has a Grand Cascade water feature (the largest of its kind in the UK), a vast Rose Garden, an Ornamental Garden, and the Poison Garden — a locked enclosure containing over 100 poisonous plants including belladonna, ricin, and mandrake, accessible only on guided tours (included with garden entry). Allow 2 to 2.5 hours for the full garden.

Late Afternoon: Walk to Barter Books on Narrowgate — one of the largest secondhand bookshops in Britain, housed in the Victorian railway station that closed in 1968. The building has been converted into one of the most atmospheric bookshops anywhere: high ceilings, an original model railway that runs along the shelves, open fires, and a cafe. This is where the original Keep Calm and Carry On poster was found in 2000 in a box of unsorted books. Free to browse. Allow at least an hour.

Dinner: Cafe Martinique on Market Street does good brasserie food in a relaxed setting — the most reliable dinner option in Alnwick town centre. Mains £14-£24. Alternatively, Brasserie 36 at the White Swan Hotel is the formal option for a special evening.

Day 2: Bamburgh Castle and Holy Island

Morning (Early): Drive 15 miles north on the B1340 to Bamburgh Castle. The castle rises 45 metres above the Northumberland coast on a volcanic dolerite outcrop — one of the most dramatically positioned fortresses in England. The interior is richly furnished; the grounds look out over a wide sandy beach. Entry: adults £15.50, children £8. Arrive when it opens (usually 10 a.m.) to have the castle and beach to yourself for the first hour. Allow 2 hours.

Mid-Morning: Walk the beach below Bamburgh Castle northward. The combination of castle overhead, Farne Islands visible offshore, and the Cheviot Hills behind makes this one of the finest coastal walks in northern England. The beach is almost always uncrowded.

Afternoon: Drive 12 miles north of Bamburgh to Holy Island (Lindisfarne). The island is connected to the mainland by a causeway that floods at high tide — check the safe crossing times before you go (posted at the causeway and on the Northumberland County Council website). Holy Island has Lindisfarne Priory (English Heritage, adults £9.80), the 16th-century Lindisfarne Castle (National Trust, adults £11.50), and the smallest distillery in England. Allow 2 to 2.5 hours.

Return: Back in Alnwick by early evening. A drink at the Dirty Bottles pub on Narrowgate — a pub with a display of dusty old bottles in the window that have reportedly not been touched since the landlord died centuries ago, according to local legend. The reality is more recent but the pub embraces the story enthusiastically.

Practical Notes

• Check Holy Island causeway crossing times before planning Day 2. The island is inaccessible during high tide and the timetable changes daily.
• Book the Treehouse Restaurant well in advance — it fills up on weekdays as well as weekends.
• Alnwick Castle closes in winter (November to March typically). Check the castle website before visiting.
• Barter Books is open every day including Christmas Day and is the best wet-weather option if Northumberland delivers its characteristic rain.
• The Alnwick Garden Poison Garden tours run at set times — arrive when the garden opens and ask at the entrance for the first available tour.

Frequently Asked Questions

Is Alnwick Castle where Harry Potter was filmed?

Yes. Alnwick Castle was used for the flying lesson and Quidditch training scenes in Harry Potter and the Philosopher’s Stone (2001) and Chamber of Secrets (2002). The broomstick training scene takes place in the castle’s outer bailey, and the location is clearly recognisable on screen.

How far is Holy Island from Alnwick?

Holy Island is about 20 miles north of Alnwick — approximately 35 minutes by car when the causeway is passable. Always check crossing times before departing: the causeway floods twice daily and visitors who misjudge the tides are occasionally stranded.
