Practical Tips
- Book the Treehouse Restaurant in advance — it fills completely and walk-ins are rarely possible.
- Holy Island: always check causeway crossing times before you go. The schedule changes daily and stranded visitors are a regular occurrence.
- Alnwick Castle closes November to March. If visiting in winter, the Garden, Barter Books, and the coast remain excellent.
- The Farne Islands seal and seabird colonies are best seen April to August. Boat trips from Seahouses run weather permitting — book ahead in summer.
- Northumberland has some of England’s darkest skies. Kielder Water (30 miles west) is an International Dark Sky Park — worth a night if stargazing appeals.
Frequently Asked Questions
Is Alnwick worth visiting?
Yes — strongly. Alnwick combines a remarkable castle, an extraordinary garden, and one of the world’s great bookshops in a small town, with the best-preserved stretch of the English coastline within 25 miles. It consistently underperforms on visitor numbers relative to its quality.
Is the Alnwick Garden worth it?
Yes. The Poison Garden alone justifies the entry price for most visitors. The Grand Cascade and the Treehouse are additional reasons. Allow 2 hours minimum.
