Things to Do in Alnwick: The Complete Guide

Alnwick punches well above its weight for a market town of around 8,000 people. Between the castle, the gardens, one of Britain's best bookshops, and hundreds of acres of free parkland, there is genuinely enough here to fill a long weekend -- and enough to keep residents discovering new things for years. Here is what's worth your time.

Alnwick Castle

The centrepiece of the town and one of the most visited castles in England. Alnwick Castle has been home to the Percy family -- the Dukes of Northumberland -- for over 700 years. It is the second largest inhabited castle in England, after Windsor.

Most visitors will recognise it as Hogwarts from the first two Harry Potter films. The Outer Bailey, where Harry had his first flying lesson, is now home to broomstick training sessions that run daily during opening hours -- genuinely good fun for children and adults alike.

Beyond Harry Potter, the castle offers a surprising amount. The State Rooms house one of the finest private art collections in England, including works by Canaletto, Titian, and Van Dyck. The falconry displays by Domus Falconarius run twice daily and feature owls, hawks, and eagles in free flight above the castle walls. There are also regular historical re-enactments, archery sessions, and a Dragon's Quest activity trail for younger children.

The castle is open from late March to the end of October. An adult ticket costs around 20 pounds and covers entry to both the castle and grounds. Family tickets are available and worth booking online in advance to skip the queue.

Best for: If you're visiting Alnwick Castle with children, allow at least half a day. Between broomstick training, the falconry, Dragon's Quest, and the State Rooms, there's more than enough to fill a morning or afternoon.

The Alnwick Garden

Just next to the castle, The Alnwick Garden is a major attraction in its own right. Created by the Duchess of Northumberland from 2001, it has grown into one of the most visited gardens in the north of England.

The Poison Garden is the headline draw -- a locked enclosure filled with around 100 toxic and narcotic plants, accessible only on guided tours. Visitors learn about deadly nightshade, strychnine, and cannabis in an entertaining and surprisingly educational format. The tours run throughout the day and are included in the entry price.

Lilidorei is the garden's enormous play structure, billed as the world's largest play village. Opened in 2024, it features treehouses, towers, rope bridges, and slides spread across a woodland setting. It's aimed at children up to around 12 and is busy during school holidays -- arrive early.

The Treehouse Restaurant is one of the most unusual places to eat in Northumberland. Built from sustainably sourced wood around living trees and accessed via a rope bridge walkway, it serves a modern British menu. Booking is essential, especially at weekends and during school holidays.

The garden also hosts seasonal events throughout the year, including the Cherry Blossom Festival in spring, when the ornamental cherry trees in the Cherry Orchard are in full bloom. Check the website for exact dates, as they vary with the weather.

Hulne Park

This is Alnwick's best-kept secret for anyone who enjoys walking. Hulne Park covers around 3,000 acres of parkland, woodland, and river valley just north of the town centre, and entry is completely free.

The main draw for walkers is the Hulne Priory, a remarkably well-preserved 13th-century Carmelite friary set on a hilltop within the park. The circular walk from the Ratten Row entrance to the priory and back takes around two hours at a moderate pace. The route follows the River Aln through mature woodland before climbing to the priory ruins, which offer wide views across the Northumberland countryside.

The park is open to pedestrians only -- no cars, no bicycles, no dogs. This makes it unusually peaceful. It is managed by the Northumberland Estates and the walking is free year-round, though opening hours are seasonal (typically dawn to dusk).

Best for: Hulne Park is closed on certain days for estate management. Check the Alnwick Castle website or the notice board at the Ratten Row entrance before setting out.

Barter Books

Barter Books is one of the largest secondhand bookshops in Britain, housed in the former Alnwick railway station. The building itself is worth visiting -- a handsome Victorian station with a vaulted roof, an open fire in winter, and a model railway running above the bookshelves.

The stock runs to hundreds of thousands of volumes across every conceivable subject. There is a cafe inside serving decent coffee and cakes. Barter Books is also the shop that rediscovered the original "Keep Calm and Carry On" poster in 2000, before it became one of the most reproduced images of the 21st century.

It is open daily and is free to browse. Plan to lose at least an hour.

Town Centre Shopping

Alnwick's town centre is one of the best in Northumberland for independent shopping. The main streets -- Bondgate Within, Bondgate Without, and Fenkle Street -- are lined with independent retailers, galleries, delis, and gift shops.

The town holds a regular market on Saturdays in the Market Place, selling fresh produce, baked goods, and local crafts. The Alnwick Station Market runs on the first and third Sunday of each month in the old railway station buildings and is worth a dedicated visit for artisan food and drink.

For eating and drinking, the town centre has a good selection of cafes, pubs, and restaurants. The quality has improved noticeably in recent years, with several places now serving food that would hold its own in Newcastle or Edinburgh.

Bailiffgate Museum

Bailiffgate Museum and Gallery occupies a former church on Bailiffgate, just below the castle. It tells the story of Alnwick and the surrounding area through local history exhibitions, photographs, and objects.

The museum runs a changing programme of temporary exhibitions alongside its permanent collection. It is volunteer-run, relatively small, and can be covered in an hour -- but it provides useful context if you want to understand the town beyond the castle and gardens. Entry is free, though donations are welcomed.

Adventure Cinema at the Castle

In summer 2026, Adventure Cinema returns to the grounds of Alnwick Castle for a series of outdoor film screenings. Watch films on a large screen with the castle as a backdrop -- an atmospheric way to spend a summer evening. Check the Adventure Cinema website for the 2026 programme, dates, and ticket availability. Bring blankets and warm layers; Northumberland evenings cool quickly even in July.

Beyond Alnwick

One of Alnwick's great strengths is its location. The town sits at the junction of the A1 and the B1340, making it a natural base for exploring the Northumberland coast and countryside.

The beaches at Alnmouth (four miles), Warkworth (seven miles), and Embleton Bay (eight miles) are among the finest in England. Dunstanburgh Castle, reached by a spectacular coastal walk from Craster, is around 10 miles north. The Cheviot Hills and the edge of the Northumberland National Park are within half an hour's drive.
